Brocade Compatible 40GBASE-SR4 QSFP+ 850nm 150m Optical Transceiver


Form Factor: QSFP+.
Wavelength: 850nm.
Digital Diagnostics Functions: Support.


FOS 40GBASE-SR4 QSFP+ optical transceiver module is a high-performance module for 40G Ethernet data links over four multimode fibre pairs. The maximum transmission distance up to 150m over OM4 MMF. The four transmitters are 850nm VCSEL (Vertical-Cavity Surface-Emitting Lasers) generating four optical 10Gbps output signals. The four receivers are PIN photodiodes detecting 4x 10Gbps optical input signals. This transceiver module fully complies with the QSFP+ MSA (Multisource Agreement).
