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 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.
