The Cisco MGBLH1 is a 1 Gbps SMF optical SFP transceiver designed for data transmission up to 40 km. Operating on a wavelength of 1310 nm, this module supports duplex LC connectors, ensuring reliable point-to-point,] communication.

Its compact small form-factor pluggable (SFP) design allows compatibility with most networking devices that support Gigabit Ethernet or Fibre Channel over SMF links. The BASE-LH classification signifies its capability for long-haul connectivity across extended distances without signal degradation when paired with the appropriate infrastructure and compatible cables. Designed to operate within standard temperature ranges under normal conditions, it suits deployments requiring consistent gigabit-speed network performance in aggregation or distribution layer setups where longer-distance connections are essential.

Featuring hot-swappable functionality, this SFP transceiver can be easily inserted or removed from compatible devices without interrupting operation. It facilitates cost savings as there's no need to replace entire switches when upgrading bandwidth requirements - simply upgrade the transceivers instead.
