36 FIBRE OPTIC CABLING Loss limitation By Lite Linke www.litelinke.com The need for low loss assemblies in data centres as network speeds and data increase As data centres are evolving from 10GbE through to 40 & 100GbE, the need for low-loss multi-fibre connectivity is vital. As network speeds increase, the optical insertion loss budgets will become more stringent than ever. Headroom between the loss budgets and system performance is reducing and so then does margin for error. No longer is it okay just to use any compatible looking assembly and hope for the best; all fibre connector losses must be factored in and specified as part of the system design and vendors taken to task over conformance. With a typical configuration, identified in Fig. 1, the end-to-end link consists of a patch cord, a cassette (which includes LC adapter at the front, an LC to MTP fan-out assembly inside and an MTP adapter at the rear), an MTP to MTP trunk cable, a remote cassette and a remote patch cord. This simple system, from switch to server will include a Data Centre In A Box All the key data centre capabilities..... .......just on a smaller scale. ENCLOSURES POWER DISTRIBUTION CLIMATE CONTROL
