Typical LT1710 application

Description

The LT1710 is the ultimate "configure-it-as-you-need-it" fiber optic modem. Ideal for applications requiring high data rates, it supports asynchronous data rates up to 10Mbps and synchronous rates up to 5Mbps.

It supports most popular electrical interfaces including 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 (1300nm) or single mode (1300/1550nm), the LT1710 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 12VDC (standard), 24VDC, -48VDC, 125VDC or 115/230VAC with an external power cube.

The LT1710 is available in two versions: LT1710R Rackmount Card for installation in a 19" rack assembly or LT1710S Standalone version. Standalone or rackmount versions can be mixed or matched on either end. There are two optional versions (Model LT1710T) for extreme temperature applications (-20° to 70°C & -40° to 80°C).
