The RLH 2 Channel Analog Phone DIN/wall mount Fiber Mux System provides a method of multiplexing 2 analog (POTS) channels over a single pair of multimode or singlemode fibers. This system solves the problem of limited available fiber, reduces equipment space and lowers overall equipment costs.

In addition to two analog phone lines, the system provides two 10/100 Base-T Ethernet ports. With these additional ports, the Analog Phone Fiber Mux Systems is a complete solution for transporting phone and Ethernet data over a single fiber pair.

The system uses a DIN/wall mount style housing, with our standard 24-48VDC powering options are available. Ringdown mode is also available for applications where direct connection to phones at each end is desired. This hardened, compact DIN mount system is covered by our Limited Lifetime Warranty.

Note: The FXO and FXS units normally take a few seconds to sync with each other during initial setup or when power is turned OFF then ON. Please refer to the Data Sheet for additional operating information.

A complete system requires 2 devices of either configuration:
– One FXO device paired with one FXS device for a typical phone line extension
– Two (2) FXS device paired for a ringdown hotline
Bi-Directional single fiber models require an A side and B side unit for a complete system
