400GBASE-SR4 QSFP112 PAM4 850nm 100m/OM4 Optical Transceiver Module

For 400GBASE Ethernet use in data centres as well as high-performance computing environments, the QSFP112 SR4 400G with four channels. Equipped with four 106.25Gbps lanes, the QSFP112 module is able to handle 425Gbps of throughput. It is capable of transmitting over 60 meters using OM3 MMF, or 100 meters using OM4 MMF, which has FEC to ensure the signal is protected and is suitable for applications that require short distances.
The module’s photodetector array PIN and the 850nm VCSEL technology ensure rapid and reliable data transmission. Clock data recovery (CDR) circuits are installed on both the receiving and transmitting ends to ensure signal quality on all lines. The digital diagnostic capabilities of the module are accessible through a management interface when meeting difficult circumstances. This allows users to observe the system in real-time. The most efficient high-density and ultra-fast connections between Ethernet telecom, Ethernet, Infiniband routers, switches, as well as transport devices are made available by this 400G SR4 optical module.
