Optimux-108L
Fiber Multiplexer for 4 E1 and Ethernet

Fiber Multiplexer• Four E1 channels and Fast Ethernet link multiplexed over a fiber optic link

Transmitting Any• Various fiber interfaces: multimode, single-mode (up to 120 km), and/or
single-mode over single fiber

Traffic over Fiber• Management via dedicated Ethernet port, SNMP management station, Telnet orWeb Server• Transparent clocking

The Optimux-108L multiplexer combines
four E1 channels and an optional Ethernet
link over a fiber optic uplink.
A pair of Optimux-108L units provides asimple and cost-effective solution forconnectivity over distances of up to120 km (74.5 miles).

Optimux-108L is available in two productversions. The default is a fully-managed
unit with the management Ethernet port.
Optimux-108L may also be ordered withbasic management capabilities(Optimux-108L/BM). The latter unit isequipped with DIP switches.

UPLINK INTERFACESMANAGEMENT

POWER

Optimux-108L features a variety of built-in
optical uplink interfaces including:

Optimux-108L may be ordered with twodifferent power supplies:•850 nm VCSEL (Vertical Cavity Surface
Emitting Laser) for multimode fiber

A fully-managed Optimux-108L can beconfigured and managed remotely or
locally via the Ethernet management port
using:•1310 nm LED for multimode fiber••

1310/1550 nm laser diode or long haul
laser diode for extended range oversingle-mode fiber••

Single fiber (SF1, SF2 options) using a1310 nm and 1550 nm laser diodetransmitter with WDM technology,
which enables the laser to transmit thesignal at a different wavelength thanthe receive signal
Single fiber (SF3 option) using SC/APC(Angle-Polished Connector)
technology, with a 1310 nm laser
diode for single wavelength operation.

TRIBUTARY INTERFACES
Optimux-108L has four balanced or four
unbalanced E1 tributary channels.
Each of the four signals of the tributaryinterface is transmitted independently,
ensuring that each channel can be set to adifferent clock source.

•Wide-range AC/DC power supply
that can be connected to either an
AC power source (100 to 240 VAC),
or to a DC power source (-40 VDCto -125 VCD)•-48 VDC on-board power supply(-40 to -57 VDC).

SNMPv1 management station•Web Server•

Telnet.

An Optimux-108L/BM can be managed
remotely using one of the following:•Remote OP-108C card in an
LRS-102 or Megaplex-4100 chassis•

Fully-managed Optimux-108L unit•

Optimux-108 unit.

DIAGNOSTICS
Optimux-108L features comprehensive
test and diagnostic capabilities that
include local and remote loopbacks on theuplink interface and on each E1 tributarychannel. The loopbacks can also begenerated via the corresponding
LRS-102/OP-108C or MP-4100/OP-108Ccard or Optimux-108 units.
In Optimux-108L/BM, local and remoteloopbacks can also be generated using thelocal DIP switch of the local or remote
Optimux-108L unit.
To facilitate system diagnostics,
Optimux-108L features LED statusindicators, AIS alarm recognition, and LOS
alarm recognition on the optical link andon E1 channels 1 to 4.

PHYSICAL
Optimux-108L is a compact standalone
unit, available in a plastic or metal
enclosure. The optional rack-mountadapter kits enable installation of one ortwo (side-by-side) units in a 19-inch rack.
TYPICAL APPLICATIONS
Optimux-108L transparently extends TDM
and Ethernet services over fiber links.
Optimux-108L serves mobile operators for
2G/Wimax backhauling over fiber (SeeFigure 1).
Carriers and service providers can use
Optimux-108L for TDM and ETH
aggregation to PDH/SDH/SONET with clear
migration to IP networks over fiber.
Enterprises, utility and transportationcompanies may use Optimux-108L for
TDM and ETH services in P2P/Star
topologies over dark fiber.
