M400 Series: Applications

The M400 Series: from the UK’s MTP® specialists

CREATE DIRECT CONNECTIONS OR CHANNELS

40G and 100G | SR4 and PSM4

40G and 100G over multimode fibre

Connecting two QSFP+ or QSFP28 SR4 transceivers which are physically close together can be achieved using an M400 multimode patch cord. Complete Connect stock these in both OM3 and OM4 up to 20m with other lengths made to order.

40G can also be transmitted via other multimode transceivers, such as Cisco’s Bidi transceiver. These require different cables.

40G and 100G over singlemode fibre

There are two types of transceivers for 40G or 100G. One type requires duplex fibre links (e.g. LR4) and one type uses 8 fibre links and utilises the MTP (MPO) multi-fibre connector.

40GbE and 100GbE over multimode fibre

A QSFP+ or QSFP28 SR4 transceiver transmits using 4 x 10G (or 25G) channels. These are separated using an MTP to LC duplex (x4) 8 fibre multimode breakout cable. Complete Connect stock these in both OM3 and OM4 up to 20m with other lengths made to order.

40GbE and 100GbE over singlemode fibre

It is only possible to breakout QSFP+ and QSFP28 PLR4 (PSM4) transceivers. The 40G or 100G signal from an LR4 (or ER4) transceiver cannot be broken out into 4 parts. M400 Singlemode MTP – LC breakout cables are part of our standard stock.

40G MTP Modular Cassette

M400 Cassettes within housing panels

The some connectivity as above can be created using an M400 Cassette. Each cassette can breakout up to three QSFP+ (or QSFP28) ports into up to twelve SFP+ (or SFP28) ports.

M400 cassettes are available in both multimode and singlemode fibre. Complete Connect also offer breakout cassettes within our MX Series.

When to use this approach?

Typically the use of M400 MTP-LC Breakout Cassette Modules is ideal when the SR ports are split across multiple racks. One cassette located at end-of-row can be patched into a row of racks. This approach reduces rackspace requirements and also reduces cabling costs.

Splitting one 100G port to Multiple Ports

There are several different options when connecting QSFP28 100GbE transceivers to other ports.

Example: Splitting one 100G port to two 50GbE Ports

A 100G port can be connected to two 50G ports using an MTP conversion cable. 100G SR4 QSFP28 transceivers transmit over both multimode and singlemode as 4 x 25GbE channels. These channels use 8 fibre cores (4 fibre pairs) and require MTP (MPO type) connectors. The 8 fibres connected to the 100G transceiver, which include 4 Tx signals and 4 Rx signals can be directed as pairs to up to four other transceivers. In the case of connecting to two 50G transceivers then 4 fibres go to each 50G transceiver.

Rest assured, what ever your requirements, Complete Connect’s M400 Series will have the right cable.
