Applications
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.

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.
