R&M guarantees 40GbE over 600m links on OM4 using Finisar QSFP+ Transceivers

First launch in R&M’s Technology Alliance Partnership Program quadruples operational length for 40G solutions and helps save up to 60%.

R&M is pleased to approve Finisar® Corporation, the world’s largest supplier of optical communication components and subsystems, as their transceiver supplier. Transceivers from market and technology leader Finisar will support R&M’s high performance optical cabling solutions. R&M’s decision is aimed at supporting organisations with data centre capital expenditure savings and the implementation of leading-edge network link architectures.


The accelerating growth of data centres around the world is pushing IT infrastructure managers to adopt costly single mode connectivity for link lengths which exceed the distance limits inherent to the IEEE 40G standard for multimode fibre cabling. Enabled by R&M’s High Performance Network Connectivity (HPNC) Solutions, a new optical solution by R&M delivers the cost-efficient way to transform current 10G data centre networks to future 40G fabrics.


Vast cost savings
The combination of R&M’s multimode fibre optic cabling system and Finisar’s QSFP+ parallel fibre-optics module enables R&M to certify an extended reach solution. R&M specifies 330 metres over OM3 cabling and 600 metres over OM4 cabling, each with four MTP®* connections in between. This innovation means that the data centre industry can more easily serve distances beyond the 100m OM3 and 150m OM4 currently specified in the IEEE 802.3ba 40GBASE-SR4 standard and also farther than the 300m OM3 and 400m OM4 specified for 10 Gb/s links in the IEEE 802.3ae 10GBASE-SR standard.


A 600m reach means virtually all fibre optic links within a data centre can be deployed using the OM4 fibre optic cabling system. The radius of fabric-based architectures that use 40G uplinks to connect the aggregation and core switching layers to 600m can be significantly increased. Network architects are now offered the flexibility to deploy less expensive multimode fibre optics instead of more expensive single mode optics. This, in turn, implies cost savings of up to 60% on 600m links compared to a single mode alternative. For lengths shorter than 600m savings, greater than EUR 9,000.- per link may be realised without making any compromises on reliability, quality and future-proofing of investments.
