Applications

The TC1880 Micro Multiplexer provides a cost effective method for connecting large numbers of async or sync terminals, printers and status collecting devices. It is often used in harsh environments where EMI/RFI interference and lightning conditions may exist. The TC1880 can also be used to extend up to eight telephone lines to remote locations with Model TC1900 RS-232 or Fiber Phone Extenders.

Description

Packaged in a remarkably small pocket-sized unit, the TC1880 RS-232 Fiber Optic Multiplexer offers the lowest per-channel cost of any comparable fiber optic multiplexer currently available in today's marketplace. Using a fan-out cable adapter, the TC1880 can be configured for up to 8 Async channels, up to 4 sync channels or combinations of both.

Configurations can be easily changed in the field by replacing the fan-out adapter. For example, a user could multiplex four channels of asynchronous data and two channels of synchronous data simultaneously over one duplex fiber optic cable.

The TC1880 is compatible with all popular sizes and types of fiber optic cable. It supports data rates up to 56 Kbps and is available single mode (1300/1550nm) or multimode (850/1300nm).

Fiber optic connectors are ST or FC. Electrical connectors are DB25 female. Power is 12VDC or optional 24VDC or 115/230VAC with an external power cube. An extreme temperature version (-20°C to 70°C), Model TC1880T, is also available.
