Cisco Compatible 40GBase-SR4 QSFP+ Transceiver Module, QSFP-40G-SR4

Our Cisco compatible 40G QSFP+ modules are some of the most popular on the market today and are in many ways comparable to their popular 10G counterpart, SFP-10G-SR. These 40GBase-SR4 modules are parallel optic transceivers which are ideal for short range reaches. These transceivers utilize MPO/MTP connectors, operate on OM3 or OM4 multimode fiber (MMF), and use 850nm lasers. These modules utilize 8 of the 12 MPO/MTP fibers to transmit data over 4 duplex (4 sending and 4 receiving) parallel channels at a rate of 10Gbps/channel resulting in 40Gbps speeds. In addition, these modules can be used in a 4x10G mode which allows the module to be compatible with existing 10G transceivers. 40GBase-SR4 modules can reach lengths of up to 100m over OM3 and 150m over OM4 fiber cable.

This transceiver module is fully Cisco compatible.
