R&M uses Xena Test Equipment to Validate ‘Zero Packet Loss’ at 40G Ethernet Over Extended Distances

New White Paper from R&M examines how the right cabling and transceivers can significantly increased Network performance by reducing packet loss.

October 2014: A new White Paper released by R&M documents how network performance can be significantly increased by achieving zero packet loss when transmitting at 40 Gigabit Ethernet over extended distances.

Realizing that conventional power-loss measurement methods cannot deliver all the necessary information about link performance, R&M elected to use Gigabit Ethernet test equipment from Xena Networks to verify the their performance benchmark tests for R&M’s High Performance Network Connectivity (HPNC).

Network performance can be significantly increased by reducing packet loss. Data packets consist of fixed-size frames, as well as actual data (payload), in a variety of sizes. To optimize network performance, the payload size must be maximised and the overhead minimised. However, bit errors can result in a loss of packets, which then have to be retransmitted – which means (often cumulative) delays.

The outcome of the tests conducted by R&M validated the combination of R&M’s MTP® cabling system and Finisar’s QSFP+ parallel fiberoptics module to enable ‘zero packet loss’ transmission 40G Ethernet extended-reach solution.

R&M specifies 330m over OM3 cabling and 600m 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.
