Multi-mode optical fiber - Data Center Cabling Solutions Blog

Multi-mode optical fiber is a kind of optical fiber mostly employed for communication over short distances, such as within a building or on a campus. Typical multimode links have data rates of 10 Mbit/s to 10 Gbit/s over link lengths of up to 600 meters, a lot more than sufficient for almost all premises applications.

Multi-mode fibers are explained their core and cladding diameters. Thus, 62.5/125 um multi-mode fiber includes a core size of 62.5 um along with a cladding diameter of 125 um. The transition between the core and cladding can be sharp, which is called a step-index profile, or a gradual transition, which is sometimes called a graded-index profile. The two types have different dispersion characteristics and therefore different effective propagation distance. Multi-mode fibers might be constructed with either graded or step-index profile. Additionally, multi-mode fibers are described using a system of classification determined by the ISO 11801 standard ?a OM1, OM2, and OM3 ?a that is in line with the modal bandwidth of the multi-mode fiber. OM4 (defined in TIA-492-AAAD) was finalized in August 2009, and was authored by no more 2009 by the TIA. OM4 cable supports 125m links at 40 and 100 Gbit/s. The letters OM are a symbol of optical multi-mode.

For a long time 62.5/125 um (OM1) and conventional 50/125 um multi-mode fiber (OM2) were widely deployed in premises applications. These fibers easily support applications ranging from Ethernet (10 Mbit/s) to Gigabit Ethernet (1 Gbit/s) and, because of their relatively large core size, were ideal for use with LED transmitters. Newer deployments often use laser-optimized 50/125 um multi-mode fiber (OM3). Fibers that meet this designation provide sufficient bandwidth to support 10 Gigabit Ethernet up to 300 meters. Optical fiber manufacturers have greatly refined their manufacturing process since that standard was issued and cables can be created that support 10 GbE up to 550 meters. Cables can often be distinguished by jacket color: for 62.5/125 um (OM1) and 50/125 um (OM2), orange jackets are recommended, while Aqua is recommended for 50/125 um laser optimized OM3 and OM4 fiber.

Here I will mainly introduce these products of OM1 to you. OM1 62.5/125 fiber patch cord is a type of OM1 Patch Cable, rich in return loss and low insertion loss, OM1 62.5/125 patch cable always apply in Fiber Optic Telecommunications and high speed transmission systems. OM1 62.5/125um Multimode Patch Cables with FC, SC, LC, ST, MTRJ or MU connectors are in huge stock and able to ship. For example, FC to FC 62.5/125 Simplex Patch Cable is one of them. Those OM1 MM 62.5/125 fiber jumpers features good quality and therefore are perfect optically tested to ensure high performance. FiberStore can customize fiber cords about length or connectors to satisfy your different requirements.

And you will find OM1 Mode Conditioning Patch Cable that is normally used in pairs. It's designed for use in Gigabit Ethernet 1000BASE-LX applications. It is fully compliant with IEEE 802.3z application standards. Mode Conditioning Cables are essential in applications where new high-speed Gigabit 1000BASE-LX routers and switches are being deployed into existing multimode plants. In FiberStore, you'll find SC OM1 Mode Conditioning Patch Cable and 10G OM1 Mode Conditioning Patch Cable and many others tpyes of OM1 patch cables.
