40G 10km QSFP+ LR4 Module 1310nm SMF DDM Duplex LC 40GBASE-LR4 2 Fiber Optical Transceiver

The QSFP-40G-SR4 optical module features an MTP/MPO interface and operates at a wavelength of 850nm, generally used in multimode applications. When used with OM3/OM4 multimode optical fibers, the transmission distance is 100m and 150m respectively, mainly used for connecting network equipment within data centers. The QSFP-40G-SR4 optical module not only enables the connection between two 40G network devices using MTP/MPO fiber jumpers, but also supports the use of MTP/MPO to LC optical fiber jumpers for the connection between 40G and 10G network devices.
