Description
The TC8520 Telephone,
Ethernet & Data Fiber Multiplexer multiplexes various combinations of 2-wire
Analog POTS or 2/4-wire 600 Ohm Analog, 1 Ch. 10/100 Ethernet and optional
Serial Data channels over single mode or multimode fiber.
The TC8520 supports distances to more than 100 km and offers a two-way, "one
fiber" communication option to maximize fiber cable usage. Optional redundant
power and optics include automatic switchover for maximum reliability.
Setup, diagnostics and control is accessed via Serial Terminal, Telnet
management ports. Diagnostics include LED indicators, dry contact alarms and
local and remote loopback.
The Ethernet port auto-negotiates at 10/100 with full 10Mbps throughput and rate
control in increments of 32Kbps. It is IEEE 802.3/802.3u/802.3x compliant.
The TC8520 converts 2-wire FXS to fiber optics on the telephone side with ring
down capability and FXO on the PBX side. Because the TC8520 digitizes the analog
signals (PCM), voice quality does not degrade over extended distances. Serial
interface options are RS-232, RS-422, TTL, Dry Contact.
The TC8520 is available as standalone unit or rackmount card. The rackmount card
fits into TCRM191
or
TCRM195
19" Rackmount Card Cages. Fiber optic
connectors are ST, FC or SC. Standard power is 12VDC and includes built-in
redundancy. Optional power sources include 24VDC, -48VDC, 125VDC or 115/230VAC
with an external power cube. High temperature (-20°C to 70°C) and extreme
temperature (-40°C to 80°C) versions are also available.

Typical Application
(Application Questions)
Typical
applications include extending SDH/SONET backbones and adding Telephone
Voice, Ethernet and Serial service to existing fiber optic links. Service
Providers use the TC8520 as an efficient, cost effective method to provide
their customers withTelephone Voice, Ethernet and Serial connections. The
two-way "one fiber," option can double usage of existing fiber optic cable
plants.
