Singlemode Fiber and Multimode Fiber Optic Cable Differences

ICC White Papers

When designing a fiber optic network, the first decision installers need to make is whether to use a singlemode fiber or multimode fiber. This article makes that choice easier by explaining the differences between the two, and when installers should pick one over the other.

Comparing Singlemode Fiber vs. Multimode Fiber

Let’s compare a singlemode fiber and multimode fiber to get a better understanding.

Singlemode Fiber

A singlemode fiber has a very small core size that is less than 10 µm (10 micro-inches). The core permits only one ray of light, also referred to as mode, to be transmitted usually at 1310 nm and 1550 nm nanometers. These parameters are what make less light reflection to be produced when light passes through the core of a singlemode fiber. The result is lower attenuation or the rate measured at which the signal light decreases in intensity. Also, it allows the signal to travel further. Therefore, installers prefer to use a singlemode fiber for long distance, high bandwidth applications.

OS1 Singlemode fiber core, 125 µm (micro-inches) cladding diameter and 9 µm (micro-inches) core

Multimode Fiber

Multimode fiber has a larger core size that is 62.5 µm (62 micro-inches) or 50 µm (50 micro-inches). It directs many modes at the same time, allowing additional data to pass through the multimode fiber core. The following parameters will generate more light reflections, disperse light more, and increase the attenuation. As a result, the quality of the signal reduces over long distances. Therefore, installers prefer to use multimode fibers for short distances in local area networks (LANs).

OM1 Multimode fiber core, 125 µm (micro-inches) cladding diameter and 62.5 µm (micro-inches) core. OM2/OM3/OM4 Multimode fiber core, 125 µm (micro-inches) diameter and 50µm (micro-inches) core.

What’s the difference between singlemode fiber and multimode fiber?

Since the cores of a singlemode and multimode fiber are different, the way in which an electromagnetic wave transfers its energy from one point to another is also different.

Light Propagation

Light propagation between singlemode and multimode fibers differs. Multimode fiber obtains two types — step index and grade index. Singlemode fiber has one type — step index. The light propagation during signal transmission in a singlemode fiber reduces less than that of multimode fibers.

Multimode and singlemode light propagation. Multimode Step Index and Grade Index have shortwave lasers. Singlemode Step Index has longwave lasers


Laser diode-based fiber optic transmission equipment is required for singlemode fiber. The equipment has to be precisely calibrated to transmit light into the fiber optic cable. LED-based fiber optic equipment is typically used with multimode fiber for short distance transmissions. Also, the alignment requirements for singlemode connectors used with singlemode fiber are more rigorous than that of multimode fiber connectors.

System Cost

Even though the cost of a singlemode fiber cable is cheaper than that of a multimode fiber cable, singlemode fiber cable systems are typically more expensive. The reason being singlemode fiber requires a transceiver that has a laser with a smaller spot-size and narrower spectral width, allowing it to function at a longer wavelength. In addition, the alignment between two fibers and the tolerances between two connectors has to be more precise. The end result is a higher cost for singlemode fiber interconnects.

Chart of relative cost of using multimode fiber vs. singlemode fiber system. A singlemode fiber system is typically five times greater in cost than a multimode fiber system due to the transciever cost.

VCSEL-based transceivers that are designed for use with multimode fibers are manufactured more easily into array devices. Therefore, they have a lower cost than equivalent singlemode transceivers. Even with the use of multiple fiber lanes and multi-transceiver arrays, there are substantial cost savings over singlemode technology using single or multichannel operations over simplex-duplex connectivity. Multimode fiber systems present the lowest cost and upgrade path to 100 Gigabit Ethernet (100GbE) for standards-based applications using parallel-optic based interconnects.

Which one to choose? Singlemode Fiber vs. Multimode Fiber

Distance is the most important thing to consider when deciding to use singlemode or multimode fiber. It’s typical to install multimode fibers from 300 meters to 400 meters within a data center. Singlemode fiber can run from 10 kilometers (10km) to 80 kilometers (80km), and even farther. Installers must use the proper optics for the distance required.

The illustration below shows common features between singlemode fiber and multimode fiber. Both are incompatible and cannot be mixed between two endpoints. The optics are also incompatible.

Singlemode vs Multimode Comparison Chart. Singlemode: 9 µm core, High bandwidth and lower ateenuation, APC or UPC otpions, and used in telecom and CATV networks. Multimode: 50 µm or 62.5 µm core, lower bandwidth and higher attenuation, PC/UPC polish, and used in LAN, security systems, and general fiber networks. Similarities betweeen singlemode and multimode fiber: glass fiber, can be simplex or duplex, available in LC, SC, or ST connectors


Multimode is a better choice for transmission distances up to 550 meters in data center applications and less expensive. For distances above 550 meters, singlemode fiber is best. Besides the distance, the total cost of ownership (TCO) should also be taken into consideration. Most importantly, choosing the right fiber for the network is the intelligent choice.

84,000 Feet of CAT6 Cable Pulled in Call Center

ICC Success Stories

UT – A software company in Utah hired an ICC Certified Elite Installer to install a structured cabling system that could support Category 6 (CAT6) Gigabit Ethernet (1GbE) and fiber optic 10 Gigabit Ethernet (10GbE) bandwidths. The project site was a call center, a centralized office for receiving or transmitting a large volume of telephone calls. The installer pulled 84,000 feet of CAT6 cable from the telecom room to the workstations. Plenum cable was required to comply with the National Fire Protection Association standard NFPA 90A. Two hundred (200) wall mount J-Hooks were used to help route the cables between the locations. The installer fitted over 300 furniture faceplates configured with CAT6 keystone jacks into the office cubicles. In the telecom room, the installer mounted rack mount enclosures and loaded them with LC adapter panels that could support 48 optical fibers.

Laser Light Versus LED Light Power Sources

ICC White Papers

The optical light source is a fundamental part of fiber optic systems. A fiber optic system includes an optical fiber connected to a transmitter and a receiver. The fiber optic light source is produced by the transmitter’s drive circuit synchronizing with the signals that are transmitted. The light source also allows the fiber optic network to be tested. Loss in performance can be calculated in the cable plant – the fiber, splices, or connectors. LED, halogen, and laser are a few of the many types of existing light power sources. LED and laser are semiconductor light sources. The article explains the differences between them.

LED and laser light sources can cast microscopic light beams into an optical fiber while powering up and down billions of times every second. Both light sources are required to be turned on and off quickly for the optical signals to transfer and correspond accurately and completely.

Light Emitting Diode (LED) A. FFDI Overfilled-Launch, Spot Size 100μm, Core 62.5μm

Vertical Cavity Surface Emitting Laser (VCSEL) B. Gigabit Ethernet Short Wavelength, Spot Size 35μm, Core 62.5μm

Single-mode Laser C. Gigabit Ethernet Long Wavelength, Spot Size 10μm, Core 62.5μm


Materials within the LED fiber optic light source affect the wavelengths of light that are emitted. A basic LED light source is a semiconductor diode with a “P” region and an “N” region. Current flows through the LED when the LED is forward biased. The area where the “P” and “N” regions meet emits photons as the current flows through the LED. LEDs are usually made up of a material called gallium aluminum arsenide (GaAIAs) when emitting in the window of 820 to 870 nm.

Similar to LED, laser is also a semiconductor diode with a “P” and an “N” region. However, it provides a stimulated emission rather than the simplex spontaneous emission of LEDs. Laser has an optical cavity designed for long-term stability which is much different than LED. By slicing the opposite end of the chip, the cavity is formed producing a highly parallel, reflective, and mirror-like finish.


A common source for high speed networking is a vertical-cavity surface-emitting laser, otherwise known as VSECL. It consists of two oppositely-doped Distributed Bragg Reflectors with a cavity layer. It’s a perfect choice for the gigabit networking options because it combines high bandwidth with low cost. Between 1975 and 1977, vertical light emitting laser was introduced to resolve the planarization constraints of the integrated photonics as microelectronic technology was only available at the time.

Today, lasers are widely being used for other applications, including laser printers, a computer mouse, chip scale atomic clocks, and analog broadband signal transmission, just to name a few.

Speed, Distance, Cost

When comparing an LED to a laser, the LED is a standard light source and falls short for light-emitting diodes. A laser does provide more power and function at higher speed levels than an LED. A laser also has better accuracy while channeling light over a wider distance. Nevertheless, a laser is not as commonly used compared to an LED and carries a higher price tag.

ICC Elite Installer Installs CAT6A to the Desktop

ICC Success Stories

WI – An Elite Installer located in Wisconsin was hired to install a Category 6A (CAT6A) structured cabling system. Desktop applications required the system to support 10-Gigabit Ethernet (10GbE). The installer recommended running CAT6A straight to the desktop. A seven-foot distribution rack was installed in the telecommunications room. The installer elected to mount modular blank patch panels to the rack and configure them with CAT6A keystone jacks. This option allows future moves, adds, or changes to be made quickly. To route cables vertically, double-sided finger duct panels were mounted to each side of the rack. 17,000 feet of CAT6A blue cable was pulled throughout the entire installation. In the work area, each workstation was equipped with an outlet consisting of two CAT6A data ports.

ICC Certified Elite Installer Installs CAT5e Cabling System

ICC Success Stories

FL – An ICC Elite Installer located in Jacksonville, Florida was hired to install a Category 5e (CAT5e) structured cabling system. The project site was a multi-story building. Multiple telecom rooms were available on each level to provide connectivity to different offices. Wall mount racks were installed into the rooms and mounted with CAT5e 24-Port patch panels. The installer decided to install plenum-rated cable because it produces less smoke than traditional PVC cable. In case of a fire, the plenum-rated jacket must self-extinguish and not reignite. 30,000 feet of CAT5e cable was pulled. In the work areas, most workstations were equipped with a 1-Port single-gang faceplate configured with a CAT5e modular keystone connector. In other non-office areas, like a warehouse, 12-Port patch panels were used to act as outlets. Before the installation, the installer offered their customer ICC’s 15-year performance warranty. Once the project was done, they tested and registered the system per TIA’s Permanent Link specification with ICC. ICC then issued a proof-of-warranty certificate back to the installer with a day.

What are the Differences Between MPO and MTP Cables?

ICC White Papers

With the number of network connections needed to support 10 Gigabit Ethernet (10GbE) growing in data centers, a modern solution is needed to keep patching fields from becoming too congested. Introducing ultra-high-density cabling to data centers is a vast improvement over traditional fiber cabling. Using MPO and MTP® connectors and cables will help integrate fiber into a single interface and support the next technologies of 40 GbE and 100 GbE.

MPO Female Connector

Multi Fiber Push On (MPO)

Multi Fiber Push On, also known as MPO, was originally manufactured to facilitate high-density termination and support high speed communication networks. What started as a 12-fiber single row connector, has now evolved into 8 and 16 single row fibers that have the capability to be stacked together to create 24, 36 and 72 fiber connectors while using multiple precision ferrules. The standard for these MPO styles has been established by the International Electrotechnical Commission (IEC) and the Telecommunications Industry Association (TIA). The international standard is known as IEC-61754-7 where as the TIA standard is TIA-604-5.

MT Ferrule

The mechanical transfer ferrule, a multi-fiber ferrule, is important for fiber alignment. It’s required to hold intense tolerances for precision during the molding process as this affects the shape, tolerance and material composition of alignment pins. The result will determine the alignment of the pins and holes as well as the eccentricity and pitch of the fiber.

MTP Connector

MTP connectors are designed to enhance optical signal and mechanical performance while providing lower insertion loss over MPO connectors. The ferrule of the MTP connector floats to retain physical contact on mated pairs if there is strain on the cable. The elliptical shaped, stainless steel guided pins in an MTP connector are less likely to cause damage compared to an MPO connector’s pins. The MPO connector has chamfered guided pins that can chip the ferrule and cause the material to drop into the guided pin holes or on the ferrule end face. MTP connectors are built with metal pin clamps that help center the push spring. The spring design prevents damage by maximizing ribbon clearance for 12 fiber and multifiber applications. A variety of MTP connectors are offered to accommodate a variety of applications: Type of boot, round or loose fiber cable, oval jacket or bare ribbon fiber, just to name a few.
MTP Guide Pin vs MPO Guide Pin


MPO connectors can directly interconnect with other MPO based infrastructures, due to being compliant with MTP standards outlines in IEC standard 61754-7 and TI-604-5.


Below are the four types of wiring using 12-pin MTP connector: Straight-through, cross-over, pair flipped, and universal.

Straight through, pair flipped and Universal wiring are all configured key up to key-down for mirrored signals. However, they do vary based on their uses. Straight through wiring are mostly used for patch panels. Pair flipped wiring incorporates a duplex pair-wise flip with the fiber location left to right connector and universal wiring incorporates an even/odd flip with the same left to right fiber location. Cross-over wiring is configured as key-up to key-up with unmirrored signals. Crossover uses include switches, transceivers, and electronic devices.

Type A (Straight-through) 1:1 Key up to Key down
Type B (Cross-over) Crossed Key up to Key up
Type C (Pair Flipped) Pairs Crossed Key up to Key down

What are the Differences Between Fiber Optic Speed and Distance?

ICC White Papers

With the demand for greener data centers that can support higher bandwidth at long distances steadily growing, fiber patch cables are being used for installations more frequently. In order to establish which fiber optic cable is most appropriate for the job, two primary layers must be understood first: the core and cladding.

Basic fiber cable structure: core, cladding, and insulation

The Core

At the core of an optic cable is a cylinder made of either glass or plastic. Cladding, which is what surrounds the core, is also made of glass or plastic.

The amount of light that is able to transmit through the fiber is dependent on the diameter of the outer core: The larger the core, the more light is able to pass through. Finding the diameter of the outer core is done by finding the average of the diameters of the smallest circles restricted to the core-cladding boundary. The mode field diameter is another measurement that defines the maximum intensity of light. Singlemode fiber has a larger diameter due to light entering the cladding.

There are three common core sizes: 62.5/125 (62.5 µm), 50/125 (50 µm) and 9/125 (9 µm) and they are measured in microns, which equates to one-millionth of a meter. Singlemode fiber has a narrow diameter at 8.3 to 10 microns and the diameter ratio of the core to cladding is 9 to 125 microns. Multimode fiber can come with a wide diameter of 50 to 100 microns, but the most common size is 50/125. The diameter ratio of the core to cladding for multimode fiber is 50 to 125 microns.

Fiber cable core sizing diagram: OM1 Multimode - 62.5 µm, OM2/OM3/OM4 - 50 µm, OS1 Singlemode 9 µm

The Cladding

Cladding is made of reflective material that surrounds the core. This not only helps keep light within the core, but also helps move it through the length of the fiber. Light can sometimes saturate the core as well as the cladding, so it is important that the cladding supports various refractive indexes as well as modes. Modern fibers are built with a higher refractive index than that of the cladding to ensure the quick dissipation of light.

More data is able to be transmitted through a multimode fiber optic cable because the light wave disperses into numerous paths within the core. However, the signal loses strength over long distances. Singlemode fiber optic cable, on the other hand, has a narrow sized core which decreases the amount of light reflections and increases the strength of the signal to travel over longer distances. However, less data is able to be transmitted compared to multimode fiber optic cable.

Fiber cable cores: multimode fiber signal - shortwave lasers, singlemode fiber signal - longwave lasers

The Coatings

The multiple layers of plastic that surround the fiber are called coatings. These coatings act as a buffer to preserve strength, absorb shock, and add an additional layer of protection. They come in a variety of microns, from 250 to 900.

Core-cladding Concentricity

There are a number of factors that can affect the loss of connection between two optical fibers. The most notable is core-cladding concentricity; this affects the quality of light transmission. Other factors include fiber core to fiber cladding as well as ferrule edge to ferrule bore. Having the diameter of the fiber mirror the diameter of the bore can also affect the concentricity.

ICC’s fiber patch cables are individually inspected to not exceed 1.5 microns, which helps keep the core as close as possible to the center. This inspection helps remove the possibility of misalignment and decreases optical loss within the core-cladding offset.

Bad Concentricity vs. Good Concentricity

Bandwidth versus Distance

The chart below shows the comparison between fiber optic bandwidth and distance. As the data rate in bandwidth increases, the distance decreases.

Data Rate Fast Ethernet
1Gb Ethernet
1Gb Ethernet
1000BA SE-LX
10Gb Base SE-SR 40Gb Base SR4 100Gb Base SR10

Multimode 50/125 200 meters 550 meters Not Supported 400 meters 150 meters 150 meters

This chart displays the differences between Singlemode and Multimode fiber optic cables. Singlemode OS1, covers up to 10,000 meters, which is 50 times more than what multimode can cover. Multimode comes in four different categories: OM1, OM2, OM3, and OM4. The most commonly used are the OM1 and OM2. These fibers are used to support 1Gb Ethernet applications and are supported themselves with 10 Gigabit Ethernet (10GbE) at a length of 33 meters and 82 meters, respectively. OM3 and OM4 cables, which are laser-optimized, are also supported by 10GbE but can run distances of 300m and 550m.
