TC1705 Stand Alone
The TC1705 is the ultimate "configure-it-as-you-need-it" 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.
Distances up to 80km* are possible depending on various factors including electrical interface, optical transmitter, number of fiber optic connectors and fiber type and quality. Power redundancy is standard. Optical redundancy is optional.
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.
Available for multimode (850/1300nm) or single mode (1300/1550nm), the TC1705 is compatible with all popular sizes and types of fiber optic cable. Fiber optic connectors are ST or FC. Electrical connectors are DB25 female. Power is standard 12VDC, optional 24VDC, -48VDC, 125VDC or 115/230VAC with an external power cube.
The TC1705 is available in two versions: TC1705R Rackmount Card for installation in a 19" rack assembly (TCRM192 or TCRM196) or TC1705S Standalone version. Standalone or rackmount versions can be mixed or matched on either end. There are two optional versions (Model TC1705T) for extreme temperature applications (-20° to 70°C & -40° to 80°C).
