The Lumentum CloudLight™ 200G QSFP56 FR4 modules built-in optical MUX and DEMUX component. This transceiver is designed with four CWDM DFB lasers (Distributed Feedback Laser) and four photodiodes. The module has four independent electrical input/output channels operating at 53.125 Gbps per channel.
It is designed in the QSFP56 form factor and the electrical interface is based on 200G CAUI-4 in module retimed interface. It is designed with DFB laser which can offer low cost, low power consumption, the high-temperature range for customers. It provides an excellent solution for 200G data transmission over up to 2 km single-mode fiber. The DDM functionality (alarm and warning features) is integrated into the design via an I2C serial interface per the Multi-Source Agreement (MSA) SFF-8665.
