Compare Multimode Fibre Optic Cabling
Understanding the types of fibre can be critical to the design of the network infrastructures performance, especially if you are planning a new build or upgrade of an existing fibre backbone.
As well as fibre type, the network equipment should be factored into the network design from day one. Even if you are working to short-term requirements initially, for example GigaBit connectivity, but with a plan for higher 10GigaBit network performance requirements in the medium to long-term. It is critical that you install the right performance fibre cable to meet both needs.
OM1 – core size 62.5/125 µm. This was commonly used from 1980 to 2000 and is now subject to removal from many sites due to its low data carrying capacity and distance limitations.
OM2, OM3 and OM4 core size – 50/125 µm. These have become the most popular fibre types of recent years, with OM3 being the most common 10GB link due to its high performance over common distances. However, for sites requiring multimode connectivity over longer distances, OM4 is the preferred choice, especially for sites planning on future proofing their network backbone.
We have created a quick reference guide below as a general guideline. For further information on our multimode fibre optic cabling services or to arrange a site visit please call 0116 412 0170 or email sales@ccn-systems.co.uk
