QSFP+ BiDi Modules

40G QSFP+ Bidirectional Optical QSFP+  For a cost effective and high quality solutions to upgrade an existing 10G network to a 40G network.

There is no physical difference between the 40G QSFP+ BiDirectional module (BiDi) and the 40G QSFP+ SR, both will utilise QSFP+ slots in vendor switches. Also, the 40G QSFP+ BiDi and the 40G QSFP+ SR reach distances up to 150 meters over multi-mode fibre. The difference is that the QSFP+ BiDi uses LC connector and the QSFP+ SR uses MPO connector.

Due to the difference in the connector The 40G QSFP+ Bidi is the perfect solution to an easy upgrade for 10G networks currently using 10G SFP+ SR SFP's.

For an existing 10G Network all the 10G transceivers use fibre cable with LC connectors. If you cannot upgrade the cabling the most effective route to increase Network capacity is to use New Vendor Switches with QSFP+ ports and then utilise the QSFP+ BiDi modules. This enables you to upgrade a network from 10G to 40G as crucially the LC connector of the 40G QSFP+ BiDi allows to reuse the existing cables of a 10G network.
