TLPX-1001 / TLLX-1001     Telephone/Intercom     Click for larger TLLX-1001 Photo
For Tone-type POTS* Applications  

 Fiber Optic Telephone Application  

The TLPX/TLLX-1001 system consists of the TLPX-1001 transmitter and TLLX-1001 receiver. Both units provide a fiber optic interface between a standard tone-type telephone and the standard US telephone line (POTS*). All functions including full duplex audio, dial tone, ringing and connect/disconnect are supported. Using a pair of TLPX-1001 you can create a phone to phone intercom system.

Both multimode and single-mode fiber versions are available and connections to and from the telephone and telephone line are by means of standard modular plugs. In addition, integral LEDs  are provided on both units to continuously indicate the presence of the off-hook condition as well as the presence of operating power making system troubleshooting simple.
