The TC1100 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 TC1100 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.

An extreme temperature version (-20C to 70C), Model TC1100T, is also available.

Typical Application (Application Questions)

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.
