Hotswappable design and low power consumption: this optical module enables easy installation and maintenance while optimizing energy use, reducing operating costs, and minimizing downtime. 1.25 Gbps data transmission with LXSM1310 SFP optics: provides up to 1.25 Gbps transfer rate for Gigabit Ethernet needs. Longdistance capability: uses 1310 nm singlemode fiber to ensure low signal loss and support distances up to 40 km, suitable for extensive fiber networking. Twofiberinterface, fullduplex operation: in data centers, enterprise networks, or any setting requiring longrange connectivity, two fiber interfaces support fullduplex communication for enhanced efficiency. Compatibility and performance: designed around the LXSM1310 optical module with 1310 nm singlemode fiber, optimized for reliable longrange connectivity and energyefficient operation. Practical use scenarios: 1) Data center uplinks: connect servers or access switches to core switches over longer distances within the data center or campus, benefiting from reliable 1.25 Gbps throughput and easy hotswappable maintenance. 2) Interbuilding links on a campus: link buildings up to 40 km apart, maintaining Gigabit Ethernet performance with low signal loss across the fiber. 3) Remote office connectivity: extend the headquarters network to remote offices or distant sites with a stable, fullduplex, longrange fiber connection using two fiber interfaces.
