The Siemon XCRR400SR4-3A1G is an OSFP (Octal Small Form-factor Pluggable) transceiver designed for 400 Gigabit Ethernet applications utilizing SR4 optics. It employs PAM4 signaling to achieve its high data rate over parallel multimode fiber. This transceiver is intended for short-reach deployments within data centers or high-density network aggregation points where 400GbE connectivity is required. Its pinned MPO/APC connector ensures secure fiber termination and optimal signal integrity. The XCRR400SR4-3A1G model specifically supports the SR4 standard, meaning it uses four transmit and four receive lanes, each operating at 100Gbps, for a total of 400Gbps.
This OSFP transceiver is compatible with network switches, routers, and servers equipped with OSFP ports that support 400GBASE-SR4 standards. It is designed for use in environments requiring high-bandwidth, short-distance optical interconnects, such as within racks or between adjacent racks in data center deployments. Ensure your host equipment's firmware and hardware support OSFP 400G SR4 modules for proper operation.
The OSFP form factor requires careful handling. Ensure the OSFP cage on the host equipment is clean and free of debris before insertion. The MPO/APC connector should be aligned and seated firmly to establish a reliable connection. Avoid excessive force during insertion or removal. The transceiver operates within standard data center temperature ranges; consult your host equipment's specifications for environmental limits.
