MODEL LT1100

RS-232 Async/Sync Fiber Optic Modem

Async Data Rates up to 64Kbps
Sync Data Rates Up to 128Kbps
Selectable Internal Clock
Multimode or Single Mode (850/1300/1550nm)
Multiple Troubleshooting LEDs
Sturdy Compact Metal Case

Applications
Typical applications include linking remote terminals or printers to host computers, tail circuits to existing multiplexers and extending data communications links. Fiber Optic Modems are also ideal for connecting data communications devices in harsh manufacturing or outdoor environments where EMI or RFI interference, ground loops and lightning are prevalent.

Description
Pocket Rocket modems are designed for local and campus networks up to distances of approximately 5 km multimode and 30 km single mode. Distances can vary depending on the size and type of fiber optic cable, number of connections and type of fiber optic connectivity device(s) used in a given network.

Because of its versatility, the LT1100 is ideal for connecting a variety of either synchronous (internal or external clock) or asynchronous communications devices to a host computer. Featuring switch-selectable internal clock rates, it is a medium speed, low cost synchronous RS-232 fiber optic modem.

The LT1100 supports external synchronous data transmission up to 128 Kbps and all popular internal clock rates, including 2.4K, 4.8K, 9.6K, 19.2K, 38.4K, 64K and 128K. It supports asynchronous data rates up to 64 Kbps. It is available for both single mode (1300/1550nm) and multimode (850/1300nm) formats. Fiber optic connectors are ST or FC. Electrical connectors are DB25 female.
