Mellanox 40g Qsfp Lr4 Compatible Duplex LC Ddm Lr4 1310nm 10km 20km Dom SMFOptical Module QSFP 40G LR4
The QSFP+ 40G-LR4-10km module is a highly integrated 4x10G transceiver focused on reach, bandwidth, density, and cost for high port-count 40G systems, and client-side 40G interfaces. It is compliant with the QSFP+ MSA. It is interoperable with LR4 transceivers over a 10 km reach.
This transceiver is compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 and OTU3 C4S1-2D1 standards. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ MSA, to allow access to real-time operating parameters.
Applications: data centers, high-performance computing networks, enterprise core, and distribution layer applications.
