4x25Gb/s CWDM4 TOSA for 100 Gb/s

Currently Viewing:

The Broadcom CWDM4 TOSA is an uncooled, 4 × 25-Gb/s, 1310-nm CWDM transmit optical sub-assembly, consisting of four high-reliability, direct-modulated DFB lasers, integrated-driver ICs for the lasers, monitor PIN photodiodes, and an optical multiplexer to combine the outputs from the four lasers. These elements are packaged with an LC receptacle. The electrical interface is through flex connects. The TOSA is intended for use in QSFP28, CFP4, and other types of modules, for links up to 2 km.
Supported module specifications include but are not limited
to the CWDM4 MSA.
