Description
The
TC8800 is a 4-to-28 Channel Telephone Fiber Optic Multiplexer
that converts 2-wire FXS
(foreign exchange subscriber) to fiber
optics on the telephone side
with ring down capability and FXO (foreign
exchange office) on the PBX
side. In addition to the telephone
channels, it can also
support RS-232, RS-422, RS-485, TTL, and Dry
Contact interfaces. Each
telephone and data channels can be mixed
and matched up to a maximum
of 28 channels (seven cards). The
interfaces are divided up in
increments of four channels per card.
Since the TC8800 digitizes
the analog signals (PCM), voice quality
does not degrade over
extended distances. Distances up to 30km* are
typical over single mode
fiber, 4km over multimode fiber.
Diagnostics
LEDs for each channel includes Tx, Rx, FXO, FXS, Ring,
VccA, VccB, PWR A and PWR B.
Power redundancy is standard, optical
redundancy is optional.
Fiber optic connectors are ST or FC. Electrical
connectors are RJ-11. Power
is standard 115/230VAC; Optional 24VDC
or -48VDC. The TC8800
requires the TCRM197 19” Rackmount Card
Cage with one power card.
The
TC8800 is based on modern FPGA (field programmable gate
array) technology. As a
result, it benefits users by enabling optimum
flexibility, low current
consumption, high reliability and maximum
MTBFs.

Typical Application (Application Questions)
The
TC8800 is frequently used to
link/extend telephone lines
between two building. It is
also
used in harsh environments
where
ground loops, EMI/RFI
interference
and lightning conditions may
occur.
