OM3 and OM4 Fiber Patch Cables

Multi-mode fiber patch cable, which is composed of a fiber optic cable terminated with multi-mode fiber optic connectors at both ends, is a type of optical fiber mostly employed for communication over short distances, such as within a building or on the campus. There are four common kinds of multi-mode fiber patch cable: OM1, OM2, OM3 and OM4 fiber patch cables. OM1 and OM2 fiber patch cables are commonly used in premises applications supporting Ethernet rates of 10 Mbps to 1 Gbps. While OM3 and OM4 fiber patch cables are developed to accommodate faster networks such as 10, 40, and 100 Gbps. The following figure shows the differences between OM1, OM2, OM3 and OM4 cables on diameter, jacket color, optical source and bandwidth:

OM1, OM2, OM3 and 0M4

Compared with OM1 and OM2 fiber patch cables, OM3 and OM4 fiber patch cables are more suitable for today’s higher-speed networks. This article will give a brief introduction to the similarities and differences of OM3 and OM4 fiber patch cables.

Similarities of OM3 and OM4 Fiber Patch Cables

The first thing to note is that the connectors of OM3 and OM4 fiber patch cables are the same. The commonly used connectors are LC, SC, FC and so on. In addition, the termination of the connectors is the same as well. As for the fiber optic cable, both OM3 and OM4 fiber patch cables use 50/125 micron (“50” represents the diameter of the core, and “125” represents the diameter of the cladding) multi-mode fiber cables. Furthermore, the fibers of OM3 and OM4 fiber patch cables are all laser optimized multi-mode fibers (LOMMF), which are designed for use with 850nm vertical-cavity surface-emitting lasers (VCSELS). Last but not least, OM3 and OM4 fiber patch cables have the same aqua sheaths.

Differences Between OM3 and OM4 Fiber Patch Cables

Compared with the OM3 fiber patch cables, the cable of OM4 fiber patch cables has a lower attenuation and operates at a higher bandwidth. Both these two factors mean that less power is lost in the transmission of signal. That’s to say, the transmission distance of OM4 fiber patch cables is further than that of OM3 fiber patch cables. Furthermore, the effective modal bandwidth (EMB) of OM3 and OM4 fiber patch cables is different as well. The followings are detailed information about the EMB and transmission distances of 10G OM3 fiber patch cables and 10G OM4 fiber patch cables.

The 10G OM3 fiber patch cable specifies an 850nm laser-optimized 50 micron cable with an effective modal bandwidth (EMB) of 2000 MHz/km. It can support 10 Gbps link distances up to 300 meters.

The 10G OM4 fiber patch cable specifies a high-bandwidth 850nm laser-optimized 50 micron cable with an effective modal bandwidth of 4700 MHz/km. It can support 10 Gbps link distances of 550 meters.

Fiberstore offers both OM3 fiber patch cables and OM4 fiber patch cables terminated with different fiber optic connectors (LC/SC/ST/FC/MTRJ/MU/E2000/SMA).

Armored Fiber Optic Patch Cable Ordering Guide

Fiber optic patch cable is an important cable component for fiber optic networks, the armored fiber optic patch cables are specially designed for harsh environment in in aerospace, automotive, industrial, medical, and military applications. FiberStore provides a huge selection of armored fiber optic patch cables in any configuration, with any connectors types, cable modes, and lengths.

Armored fiber patch cable is a round, compact and very tough duplex patch cable with flexible armouring under PVC or LSZH jacket, providing exceptional crush and kinking resistance. Armored fiber patch cord is different from standard fiber optic patch cables, the very commonly used fiber optic patch cables structures is like this: fiber glass core in the center of the cable, cladding outside the fiberglass for protection, Kevlar outside the cladding, Kevlar is soft as well as very strong material, then the outside is the cable jacket. Traditional fiber optic patch cords are tender equipment, people cannot bend it too much or the fiberglass will be damaged and broken, which is not suitable for harsh environment.

Armored fiber optic patch cables are with the same types of fiber optic connectors as the commonly used types, the difference is the cable itself. Armored fiber optic cables are typically used for indoor applications, with the same outer diameter of common types 2mm or 3mm. The difference is armored fiber optic cables are with stainless steel tape just inside the cable jacket and outside the Kevlar, this stainless unit provides extra feature as well as retain all the function that a common type optical fiber patch cable can give. What’s more, armored fiber optic cords are anti-rodent, and it can be handled as electric cables. It is not easy to get damaged or cut, and it can resist an adult step on it.

What’s the Difference Between Optical Fiber Patch Cable and Fiber Pigtails

Q: What’s the difference between fiber pigtail & fiber patch cord. Can we use a patch cord as pigtail by cutting in the middle of the cable?

I find such questions now and then on the Internet, it’s true that there are still some peoples that are not familiar with but still interested in such knowledges. Keep this in mind, we would like to take this topic into the discussion by collecting opinion from related answers:

For some people, an optical fiber patch cable is ruggedise (providing additional fiber protection) and a pigtail is not (and therefore more brittle).

“I would expect pigtails while dealing with optical components, while when dealing with patch panels, equipment interconnections, etc. I would expect patch cables.” “I would also expect patchcables to be double-ended (i.e computerized at both ends) and pigtails to be single-ended (or not terminated).”

Patch cables have connectors on both ends. While pigtails have a connector on one end and bare fiber on the other.

In my opinion, i would agree all of the above comments, and also give the simplest understanding of myself: the fiber optic patch cable = fiber optic connector + fiber optic cable + fiber optic connector, while the fiber optic pigtail = fiber optic connectors + fiber optic cable. We can really use a patch cord as pigtails by cutting in the middle of the cable.

Officially speaking, fiber optic patch cable, often called fiber optic patch cord or fiber jumper cable, is a fiber optic cable terminated with fiber optic connectors on both ends. I have two major application areas: computer work station to outlet and fiber optic patch panels or optical cross connects distribution center. Fiber optic patch cables can be divided into different types based on fiber mode, cable structure, connector types, connector polishing types and cable sizes. All types of fiber optic patch cables can be found at FIBERSTORE.COM, LC patch cable is the most commonly used, other connector types include ST, SC, FC, etc. Which can be either the same types of connector on both ends, or different connectors on each end (Hybrid fiber optic patch cables).

Fiber optic pigtail is a piece of cable terminated with fiber optic connectors at only one side of the cable while leave the other side no connectors, so that the connector side can link to the equipment and the other side can be melted with optical cable fibers. Pigtail fiber optic cables are usually used with fiber optic management equipment like ODF, splice closures and cross cabinets.

Commonly used fiber optic pigtails types are FC, LC, MU, E2000, MTRJ and ST pigtail. According to the fiber mode types, there are single mode types and multimode types.

The pigtail, when separate from a line, looks like a bundle of loose, capped wires that are bound together at one end. The bound end connects to the main cable, where the individual strands of the fiber pigtail are permanently fused, or spliced, to the multicore cable. When the process is complete, the pigtail is a non-removable piece of the system.
