Cisco Linksys MGBLH1 Compatible 1000BASE-LH SFP Transceiver Module (SMF, 1310nm, 40km, LC) is designed to establish Gigabit Ethernet links over single-mode fiber (SMF) using LC duplex connectors up to 40 km in distance. It operates at 1310nm and consumes less than 1 W of power, providing a stable and reliable option for long-distance data transmission while optimizing energy performance.
This transceiver is widely used in data centers, enterprise LANs, storage area networks (SANs), and communication systems for ISPs to deliver solid interoperability and adaptable options with many popular switches, routers, and network interface cards (NICs). Each transceiver is tested for consistency and performance in multi-vendor operating environments.
