The Siemon XCRQ400SR4M3A1G is a 400G QSFP-DD SR4 transceiver module designed for high-density, short-reach applications within data centers and enterprise networks. It leverages parallel optics to deliver 400 Gigabit Ethernet connectivity over MPO/MTP fiber optic connectors, enabling high-speed uplinks and inter-switch links where bandwidth demands are critical. This module is engineered for environments requiring maximum port density and performance.
This module is compatible with network switches, routers, and servers equipped with QSFP-DD (Quad Small Form-factor Pluggable Double Density) ports. It is designed to meet the stringent requirements of modern high-performance networking infrastructure, supporting 400GBASE-SR4 Ethernet standards. Ensure your network equipment has QSFP-DD ports and supports SR4 optics for optimal performance.
Proper installation requires careful handling of fiber optic connectors to avoid contamination or damage. Ensure the MPO/MTP fiber cable is clean and correctly oriented before insertion. The module draws power from the host device's QSFP-DD port and does not require external power. Operating temperature range is critical for maintaining performance and module lifespan; consult the manufacturer's specifications for precise environmental limits.
