OM5 – welcome to the board!

We are pleased to announce that the OM5 solutions are now available in the Premium-Line Systems product proposal.

As data processing centres have been becoming increasingly larger in recent years, the demand for higher bandwidth and higher data transfer rates is growing. Recently, OM5 was approved as a new type of high-speed Multimode fiber (MMF) for data centres. Here we’d like to consider some key features that you need to know about the OM5 fiber optic cable.

What is an OM5 cable standard?

OM5 or Wideband Multimode fiber (WBMMF), is the Multimode fiber (MMF) type that is developed to maintain wavelengths in the 850nm to 953nm range. It is considered as a new cabling solution for 40G and 100G transmission by implementing of SWDM (shortwave wavelength division multiplexing) technology.

OM5 Fiber Cable Principal Features

OM5 assures backwards compatibility with OM3 and OM4 cabling. It is also greatly cut the fiber count in 40G and 100G SWDM4 cabling. 40G and 100G transceivers operating over OM4 MTP fiber cable employ at least 8 fibers (100GBASE-SR10 uses 20 fibers), but 40/100G SWDM4 transceivers will operate only over two OM5 fibers. Multimode Optical fiber cabling channels: 



Specified effective modal bandwidth

850 nm / 953 nm

Standard distance



2000 / (n/s) MHz x km




4700 / (n/s) MHz x km




4700 / 2470 MHz x km


The OM5 fiber optic cable jacket has the specific color - lime green. OM5 fiber has the same core diameter of legacy OM3 and OM4 fiber, but it can maintain longer wavelengths above 850 nm. All the OM5 fiber solutions are guaranteed by various tests to be high quality.

It is worth recalling, that the Premium-Line fiber optic solutions meet the requirements of TIA/EIA-568 and ISO 11801 standards.
