The TC1700 High Speed Fiber Optic Modem is intended for applications requiring high data rates and handshaking.



The TC1700 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 asynchronous data rates up to 256Kbps and synchronous rates up to 2.5Mbps.  It supports most popular electrical interfaces including RS-232, RS-422, RS-449, RS-530, V.35 and TTL.  Electrical interfaces are modular and can be easily changed before or after installation.

Distances up to 30km* 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 and optical redundancy is optional.

Available for multimode (850/1300nm) or single mode (1300/1550nm), the TC1700 is compatible with all popular sizes and types of fiber optic cable.  Fiber optic connectors are ST or FC.  Electrical connector is DB25 female.  Power is 12VDC (standard), 24VDC, -48VDC, or 115/230VAC with an external power cube.

The TC1700 is available in two versions: PC Card for installation in a 19' rack assembly (TCRM192 or TCRM196), wall mount, or standalone "Pizza" box.  Standalone or rack mount versions can be mixed or matched on either end.  An extreme temperature version (-20 to 70C), Model TC1700T, is also available.
