Complete Connect M400 Series cassette modules are designed for use across all areas of today’s data centres and within enterprise networks. As 40G and 100G ports within switches (40G-BASE-SR4 and 100G-BASE-SR4) become an integral part of most networks there is a growing requirement to be able to connect these to 10G switches and servers. Often a number of servers are located in the same rack and so presentation of multiple 10G ports within top-of-rack panels is required. M400 cassettes primarily have two functions. They enable 40G/100G SR4 trunks to be connected to existing 10G/25G ports or they enable a QSFP+ or QSFP28 port to be broken out into SFP+ or SFP28 ports.

LC presentation within 19” racks

M400 Series cassettes can be housed in either the M Series 1U or 3U housing panel and are locked into place with a simple latching mechanism. This negates the need for any tooling or specialist fibre installation skills. The M400 cassettes can then be connected to the network using M400 Series trunk cables and patch cords. The M400 Series modular cassette’s unique design enables both front and rear cassette installation.
