| Cisco QSFP-40G-SR-BD Compatible 40GBASE-SR Bi-Directional Duplex LC MMF Optical Transceiver Module |
|
The 40G BiDi QSFP+ module solves the classic upgrade problem: it delivers full 40G over the same duplex LC multimode cabling already installed for 10G links. Two wavelengths travel in each direction on every fiber, so no new MPO trunks are required. Operating in the 832 to 918nm range over OM3 or OM4 fiber, the module reaches up to 100m on OM3 and 150m on OM4, matching normal SR4 distances while halving fiber count. It fully complies with the QSFP+ MSA and IEEE 802.3ba electrical specifications and provides digital diagnostics for both internal lanes. Coded for Cisco QSFP-40G-SR-BD, it is the fastest way to lift a 10G duplex plant to 40G in data centers, enterprise cores and high-performance computing networks. Related 40G QSFP products: |
