Black Box LMC270A-SM-20K-SC Fiber Optic Media Converter
Overview
The Black Box LMC270A-SM-20K-SC is a single-mode fiber optic media converter designed to extend network connectivity over long distances. This unit bridges the gap between copper Ethernet and single-mode fiber, enabling data transmission up to 20 kilometers. It is critical for deployments requiring robust, high-bandwidth links across campuses, industrial sites, or between buildings where standard Ethernet cable lengths are insufficient.
Compatibility
This media converter is designed to interface with standard 10/100/1000Base-T Ethernet devices. It is compatible with any network switch, router, or endpoint that supports 1000Base-SX/LX fiber optic standards. The SC connector ensures compatibility with other SC-terminated single-mode fiber optic cables and patch panels.
Installation Notes
Requires a standard SC-terminated single-mode fiber optic patch cable. Ensure the transmit (TX) port on one converter is connected to the receive (RX) port on the other, and vice-versa, for proper communication. The unit draws power from an external adapter (sold separately) and does not require software configuration.
