Product description

LFC series is the newest series of media converters. The LFC-100-SFP-SM120 is a 10/100Base-Tx to Singlemode long haul 120Km reach, unmanaged Fast Ethernet media converter. The RJ-45 copper port has auto-negotiation 10/100 and MDI/MDI-X features and DIP switch settings available for LFP function, converter-switch mode, and speed and flow controls for maximum flexibility and fine-tuning of the fiber or copper link connection. LED indicators to signal the power status of the converter, UTP port speed, UTP Link, and FX port Link. Used with their compatible LFC-CH12 fiber optic chassis they can be aggregated up to 12 units in a 19" wide and only 1RU of height space only. This is the highest density attainable for unmanaged fiber media converters.

The LFC-100-SFP-SM120 Fast Ethernet media converter has a duplex LC optical connector. It also offers the optional wall mounting solution for individual converters named LFC-WMK. The converter is a bundle between the LFC-100-SFP media converter and the SFP-5120-55 optical transceiver.
