Description

This 40GBASE-XSR4 QSFP+ transceiver provides 40G short-reach multimode fibre connectivity over an MPO-12 connector at 850nm. It supports reach of 300m on OM3 and 400m on OM4 fibre, making it suited to in-rack, row and short data centre links between 40G QSFP+ ports. It is a good fit for switch-to-switch and switch-to-server runs where parallel multimode cabling is already in place.
