Cisco WSP-Q40GLR4L Compatible 40GBASE-LR4L QSFP+ 1310nm 2km LC DOM Transceiver Module.The qsfp-40g-ir4 is a high-performance, low-cost qsfp-ir4 transceiver designed for 40gbe Ethernet optical communication applications. The module complies with the qsfp-msa and ieee 802.3ba 40gbase-ir4 specifications. The qsfp-ir4 transceiver module converts the electrical data of 4 x 10.3125gb/s into a 4-way cwdm optical signal and multiplexes it into a single 40gb/s optical transmission. On the receiver side, the transceiver reuses the input light of 40gb/s into four cwdm channel signals and converts them to 4 channels to output electrical data. The central wavelengths of the four cwdm channels are 1271, 1291, 1311 and 1331 nm, respectively. The module contains a duplex LC connector for optical interfaces and a 38-pin connector for electrical interfaces.

In order to reduce light dispersion in a long-distance system, the module must use a single-mode fiber (smf). Qsfp-40g-ir4-csc qsfp-x optics 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 ideal for lower cost equivalent to the Cisco WSP-Q40GLR4L QSFP-Optical Module, providing a reliable, compatible 40G QSFP-optical solution for system integrators, distributors, and end users in the data center network infrastructure.
