Product description

LFC series are newest series of media converters. The LFC-100-SC20A is a 10/100Base-Tx to single strand single-mode fiber, simplex SC connector, T:1310/R:1550nm type A, 20Km BiDi WDM reach optical port. Media converter is un-managed but 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.

A BiDirectional type A media converter using Tx:1310nm/Rx:1550nm MUST be always paired with a type B media converter that has Tx:1550nm/1310nm optics for an operational link. This is required for operation over a single strand of fiber optic. Please make sure you have the complementary model required for proper fiber connectivity. For type A the counterpart media converter is LFC-10-100-SC20B.

LED indicators 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-SC20A Fast Ethernet converter also offers the optional wall mounting solution for individual converters named LFC-WMK.
