Fiber Optic AES Transmission System

The Litelink AES fiber transmission system consists of the AT-8001
transmitter and the AR-8001 receiver. The system converts conventional AES/EBU digital audio signals into modulated light for transmission over a fiber optic cable resulting in error free and interference free transmission over distances of several miles. The AT-8001 transmitter provides AES3 and S/PDIF loop through signals. The AR-8001 produces two AES3 outputs and two S/PDIF outputs.

Both multimode and single-mode fiber optic versions are available and installation requires simply plugging in the various cables. There are no user adjustments. Integral indicators also show the presence of digital audio signals as well as operating power making system troubleshooting simple.

A system, would include
    One AT-8001-1 AES Fiber Transmitter
    One AR-8001-1 AES Fiber Receiver
    Two  PS-1205 US power supplies
For multimode fiber (~2-miles max), USA power supply.  Other versions are available for single mode fiber, and other countries such as  EU (European Union), UK (United Kingdom), AU (Australian)  at slightly higher cost.

Equipment can also be mounted in a 1U rack.   DIN Rail option is also available.
