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 115/230VAC with an external power cube.
An extreme temperature version (-20°C to 70°C), Model TC1880T, is
also available.
