The TC8108 Fiber Optic
Multiplexer, maximizes user flexibility by offering field interchangeable
interfaces, modular expandability from 8 to 64 channels and power/optical
redundancy. It supports most popular interfaces including RS-232, RS-422,
TTL, RS-485* and Dry Contact Relays. It supports data rates up to 38.4
Kbps*. Power redundancy is standard, optical redundancy is optional. Both
feature automatic switchover.
Each TC8108 unit consists of an 8-channel base unit
and up to seven optional 8-channel add-on PC Cards. These PC Cards can be
“Stacked” (in 8-Channel increments) up to 64 Channels. A 128-Channel version is
possible by using a fan-out cable to expand each RJ-11 port into two RS-232
Async channels. For units with more
than 24 Ch., the TCRM191 Rackmount Card Cages are required.
Because the electrical interfaces are modular, they are interchangeable at any
time--before or after installation. A user can mix up to four different
interfaces (in 2-Channel increments) on each 8-Channel card. Each PC expansion
Card is identified by a card number defined by a front panel DIP switch.
Diagnostics are extensive and include Local and Remote Loopback, 22 LEDs, and a
Test Signal Generator. LEDs include “Tx”, “Rx”, “Alarm”, “Vcc”, “RxA”, “RxB”, &
“PWR”. Individual “Tx” and “Rx” LEDs are provided for each channel. The
built-in test signal generator verifies both device and fiber optic link
operation. This feature benefits users by helping technicians verify that both
local & remote devices and the fiber optic link are operating normally. No
other test equipment is required for link and device verification.
The TC8108 is compatible with all types and sizes of multimode (850/1300nm) or
single mode (1300/1550nm) fiber optic cable. Fiber optic connectors are ST or
FC; electrical connectors are RJ-11. Power is 12VDC or 115/230VAC with an
external power cube. An extreme temperature version (-20° to 70°C), Model
TC8108T, is also available.
Fiber optic connectors are
ST; FC is optional. Electrical connectors are RJ11. Power is 9 to 12VDC or
115/230VAC with a power card (Model TCRMPS-01) or a power cube.

Typical Application (Application Questions)
is an inexpensive, reliable and flexible method for connecting
large numbers of printers, terminals and status collecting devices.
It is often used in harsh environments where EMI/RFI interference,
ground loops or lightning conditions may exist. The TC8108 can also be used
to extend telephone lines to remote locations with the Model TC1900
RS-232/Fiber Phone Extender.
