Deploy 40G/100G in Your Data Center

Due to the massive amount of storage is needed for high bandwidth, the demand for higher capacity of network deployment is rapidly increasing. Obviously, the conservative 2-fiber transmission is not enough to satisfied the need. And 12 or 24-fiber 40/100G Ethernet migration is quickly becoming a hot spot. This article will provide some cabling solutions for 40G/100G cost-effective and simplified migration path in data center.

10G to 40G

Take parallel optical transceiver 40GBASE-SR4 QSFP+ for example, it is structured with 12-fiber MTP connector, so it is used with 12-fiber MTP cable (only eight fibers are used, four for transmit and four for receive). The following figure shows the simplest way for migration from 10G to 40G. We can utilize 40G MTP/MPO breakout cable which has an MTP/MPO connector on one end and four duplex LC connectors on the other end. The MTP/MPO connector end is plugged into the MTP/MPO connector interface of 40GBASE-SR4 QSFP+ transceiver, while the other end is connected with four 10G SFP+ transceivers.

As for migration from 10G to 100G, we can utilize 100GBASE-SR10 CFP transceiver and 100G MTP/MPO breakout cable. The 100GBASE-SR10 CFP transceiver is structured with 24-fiber MTP/MPO connector interface. When using with MTP/MPO 24 fiber cable, the 100GBASE-SR10 transceiver only uses twenty fibers, ten for transmit and ten for receive. The following shows that one 100GBASE-SR10 CFP transceiver and ten 10G SFP+ transceivers are connected by MTP breakout cable which has 24-fiber MTP/MPO connector on one end and ten duplex LC connectors on the other end. This is the simplest cabling solution for 10G to 100G connectivity.

For 40G to 40G connectivity, we can use 12-fiber MTP trunk cable and MTP/MPO adapter panel to connect two 40GBASE-SR4 QSFP+ transceivers. We know that when deploying MTP link, we have to take polarity into consideration. Here are two cabling solutions for you. The first one uses Type A and Type B MTP trunk cable; the second one only uses Type B MTP trunk cable.

For 100G to 100G connectivity, here are three cabling solutions. The first one uses two 24fiber MTP-LC fanout cables, two 12-fiber MTP trunk cables and two MTP adapter panels; the second one uses three 24-fiber MTP trunk cables and two MTP adapter panel; the third one uses two duplex LC patch cables, two MTP cassettes and one 24-fiber MTP trunk cable. However, the third cabling solution does not use 100GBASE-SR10 CFP transceiver. It deploys ten 10G SFP+ transceivers on both sides to achieve 100G to 100G data transmission.

With the rapid development for data communication, the migration from 10G to 40G or 100G is inevitable. Then how to deploy 40G or 100G in data enter becomes the primary concern. All the transceivers and cabling assemblies presented in 40/100G connectivity solution are available in FS.COM.
