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 with Telephone Voice,
Ethernet and Serial connections. The two-way "one fiber," option can
double usage of existing fiber optic cable plants.
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 rack-mount card. The
rack-mount card fits into
TCRM191 or
TCRM195 19"
Rack-mount 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.
