TC1705
Multi-Interface Sync/Async Fiber Optic Modem (RS232/422/485/V.35/TTL)

The TC1705 is the ultimate "configure-it-as-you-need-it" multi-interface fiber optic modem. Ideal for applications requiring multiple interfaces, high data rates or full handshaking, it supports synchronous and asynchronous data rates up to 256Kbps.

It supports most popular electrical interfaces including RS-232, RS-422, RS-485 (2-wire or 4-wire), RS-530, V.35 and TTL. Electrical interfaces are modular and can be easily changed before or after installation.

Diagnostics are extensive and include a built-in Test Signal Generator, local & remote loopback tests and LEDs for Power, Alarm, Tx, Rx and all applicable control signals. The Test Signal Generator verifies both device and fiber optic link operation. It is available single mode or multimode and distances up to 80km are typical. Power redundancy is standard. Optical redundancy is optional.
