How to Make Full Use of OM5 Fibre in 40G/100G Transmission?

How to Make Full Use of OM5 Fibre in 40G/100G Transmission?

FS Official 2018-06-21

Wideband multimode fibre (WBMMF) or OM5, is a new multimode fibre (MMF) type that is designed to support wavelengths in the 850nm to 953nm range. OM5 provides a new cabling solution for 40G and 100G transmission by using SWDM (shortwave wavelength division multiplexing) technology.

Highlights of OM5 Fibre Cable

The first highlight of OM5 is that it ensures backward compatibility with OM3 and OM4 cabling since the specifications at 850 nm are the same. The second one is that this fibre greatly reduces the fibre count in 40G and 100G SWDM4 cabling. 40G and 100G transceivers working over OM4 MTP fibre cable use at least 8 fibres (40GBASE-SR4 and 100GBASE-SR4 are dominant multimode 40G/100G transceivers that use 8 fibres now, and 100GBASE-SR10 uses 20 fibres), but 40/100G SWDM4 transceivers that will operate only over two OM5 fibres are expected to be more superior in the future. (Note: currently 40/100G SWDM4 transceivers are not available at FS, but they might be provided in the next years.)

FS OM5 Cable Solution

Lime green is the selected colour code for OM5 fibre optic cable jacket. It has the same core diameter of legacy OM3 and OM4 fibre, but it can support longer wavelengths above 850 nm. FS OM5 fibre optic patch leads can be customised based on customers’ specific applications. All our OM5 fibre cables are guaranteed by various tests to be high quality.

The connectors on each end can be made as same or different LC, SC, FC, ST, etc. connectors. And the cable length can be provided from less than 1 metre to more than 100 metres, which will well meet the needs for 400m transmission of 40G SWDM4 QSFP+ module and 100m transmission of 100G SWDM4 QSFP28 module, as well as the links on the same rack or row. Also the PVC/LSZH/OFNP cable jackets are at your choice depending on your deployment environment.
