Description
The remarkably small (2" X 4") TC1880 "Micro"
RS 232 Fiber Optic Multiplexer is extremely useful for connectivity
applications including linking or extending 4 or 8 asynchronous or
synchronous terminals, printers and status collecting devices. It can also
be used to extend up to eight telephone lines to remote locations with the
Model TC1900 RS-232 Phone Extender.
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. It supports data rates up to 56 Kbps and is available
single mode (1300/1550nm) or multimode (850/1300nm).
Configurations can be easily changed in
the field by replacing the fan-out adapter. For example, a user could
multiplex four channels of async data and two channels of sync data
simultaneously over one duplex fiber optic cable.

Typical Application
(Application Questions)
The TC1880 Micro Multiplexer is a simple and
cost effective method for connecting large numbers of async or synchronous
terminals, printers and status collecting devices. It is typically used in
harsh environments where ground loops, EMI/RFI interference and lightning
conditions may affect transmission signal quality.
