Cisco QSFP-40G-CSR4 Compatible 40GBASE-CSR4 QSFP+ 850nm 400m MTP/MPO DOM Transceiver Module.Qsfp-40g-esr4 is designed for 40 Gigabit Ethernet (40gbe) applications on multimode fiber. It complies with the qsfp-msa and ieee 802.3ba 40gbase-csr4 specifications. The qsfp-csr4 transceiver integrates four data channels in each direction with each channel to provide a total of 40 gbps of bandwidth. Each lane supports a link length of 300 meters on the OM3 multimode fiber and a link length of 400 meters on the OM4 multimode fiber. The optical transmitter consists of a 4-channel 850nm VCSEL laser, a 4-channel input buffer and laser driver, control and bias blocks.

The optical receiver consists of a 4-channel pin photodiode, a 4-channel tia array, a 4-channel output buffer and a control block. Qsfp-40g-esr4-csc qsfp plus transceivers are programmed and tested to be compatible with Cisco data center switches, routers, network cards, and other optical transmission devices for 40g Ethernet and high-performance computing networks. It is the ideal equivalent for the Cisco qsfp-40g-csr4 40gbase-csr4 qsfp-optical module.
It offers reliable, compatible 40G qsfp-optical solutions for system integrators, distributors, and end users in data center network infrastructure at a lower price.
