Application
The LT1880 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.
Description
Packaged in a remarkably small pocket-sized unit,
the LT1880 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 LT1880 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 LT1880 is compatible with all popular sizes
and types of fiber optic cable. It supports data
rates up to 38.4 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
LT1880T, is also available.
