OM4 is a laser-optimized, high bandwidth 50um multimode fiber, which is used for next-generation 40 and 100 Gb/s applications. OM4 effectively provides an additional layer of performance that supports these applications at longer distances, thereby limiting the number of installations that truly require OS2 single mode fiber.
OM1, OM2, OM3, OM4 are different categories of graded-index multimode fiber optic cable. OM4 is not necessarily designed to replace for OM3. Despite the relatively long-standing availability of OM4. In most systems, both OM3 and OM4 are sufficient to cover the bandwidth needs at the distances of the current installation base. Despite the availability of OM4 glass, OM3 is quite capable of 40 and 100 Gb/s applications albeit at significantly shorter distances than OM4. The primary benefit of OM4 is the additional reach at extended bandwidth at an overall cost still less than that of an OS2 single mode system.
OM4 provides an opportunity to future-proof cabling infrastructure. It is completely backwards-compatible with existing OM3 systems. OM3 and OM4 are two grades of glass that can be inerchangeable within the transmission distance limitations. The additional bandwidth and lower attenuation of OM4 provide additional insertion loss margin. While the additional bandwidth and lower attenuation of OM4 provide additional insertion loss margin. OM4 users gain additional safety margin to help compensate for less-than-ideal cabling installations as well as provide margin for degradation due to moves, adds, and changes over the life of the installation.
FiberStore provide complete range of OM3 OM4 products, what is typical is the OM3 OM4 10G fiber cables, which are ideal for using in many applications such as Local Area Networks (LAN) backbones, Storage Area Networks (SAN), Data Centers and Central Offices.

Cable and 10G OM4 50/125 Mulitmode Fiber Patch Cable, their main difference are as following:
OM4 was developed specifically for VSCEL laser transmission and allows 10Gig/s link distance up to 550 meters. The effective modal bandwidth for OM4 is more than double that of OM3. For OM4 patch cable, it is 4700 MHz km while for OM3, it is 2000 MHz km.
We can custom the 10G OM3 and OM4 fiber cables with any connectors such as LC-LC, LC-SC, SC-SC, FC, MTRJ, MU, MPO/MTP etc and any cut lengths. For example, the OM4 50/125 ST-ST connectors patch cable can be customized with both simplex or duplex fibers. Of cause you can also custom the OM3 OM4 fiber patch cable with different connector type of cable length.
