Optimux-108, Optimux-106
Fiber Multiplexer for 4E1/4T1 and Ethernet or Serial Data

• Four E1 or T1 channels and Fast Ethernet link multiplexed over a fiber optic link
• Various fiber interfaces: multimode, single-mode (up to 120 km), and/or
single-mode over single fiber, using SFP optical modules

Fiber Multiplexers,Transmit Any Traffic
over Fiber• Automatic link backup with optional hot-swappable second main link
• Power redundancy with optional second wide-range power supply• Management via ASCII terminal, dedicated Ethernet port, SNMP management
station, or a Web-based remote access terminal

The Optimux-108 and Optimux-106
multiplexers combine four E1 or T1
channels and an optional Ethernet linkover a fiber optic uplink.
A pair of Optimux units provides a simple
and low-cost solution for connectivity overdistances of up to 120 km (74.5 miles).

For transmission reliability, an optional
modular second link provides automatic
backup upon link failure. An optional
second power supply provides power
redundancy for failsafe operation.
Each of the four signals of the tributaryinterface is transmitted independently, sothat each channel can be set to adifferent clock source.

Optimux-108, Optimux-106
Fiber Multiplexer for 4E1/4T1 and Ethernet or Serial Data•

MARKET SEGMENTS ANDAPPLICATIONS
Typical users of the Optimux-108/106
fiber multiplexers for 4E1/4T1 andEthernet or serial data include
transportation and utility companies,
government and universities, Internet
Service Providers (ISPs), and carriers
extending data and voice from SDH
networks or backhauling cellular traffic.
Figure 1 and Figure 2 illustrate
Optimux-108/106 in typical applications.

•Optimux-108/106 can be ordered with anadditional Ethernet user port (VLANtransparent), or with a V.35 interface inplace of the Ethernet user port.

Optimux-108/106 operates withOP-108C/106C modules of LRS-102 andMegaplex-4100 access nodes.

MANAGEMENT AND SECURITY
Optimux-108/106 can be configured andmonitored locally using an ASCII terminal
connected to the control port or remotely
via the Ethernet management port using:•RADview-EMS running in a
Windows or Unix environment•Web-based remote access terminal•Telnet.

To enhance security, a password tocontrol access to the Optimux-108/106
management functions can be specified.
In addition, the security of the site can beenhanced by limiting remote management
to specific management terminals ornodes.

RESILIENCYUPLINK AND TRIBUTARIES
Optimux-108/106 supports a variety ofbuilt-in optical uplink interfaces including:
850 nm VCSEL (Vertical Cavity Surface
Emitting Laser) for multimode fiber

Note: Available with FC/PC connector only.

•1310 nm LED for multimode fiber•

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

Single fiber (SF4, SF5 options) using a1310 nm and 1550 nm long haul laser
diode transmitter with WDM
technology.

Optimux-108 can be ordered withbalanced or unbalanced E1 tributaryinterfaces. Optimux-106 has balanced T1
tributary interfaces.

INTEROPERABILITY•

Single fiber (SF3 option) using SC/APC(Angle-Polished Connector)
technology, with a 1310 nm laser
diode for single wavelength operation

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 than
the receive signal

Two independent power supplies can beinstalled to Optimux-106/108 forredundancy.
In the uplink redundancy option,
Optimux-108/106 supports fully automatic
switching between the main and thebackup link.
TIMING AND SYNCHRONIZATIONThe uplink interface features only internaltiming mode.The clock of each E1 channel
is independent for each channel andtransferred transparently.

MONITORING AND DIAGNOSTICS
To facilitate system diagnostics,
Optimux-108/106 features LED statusindicators, alarms generation andrecognition, and dry contact closure uponlink failure.
Optimux-108/106 features comprehensive
test and diagnostics capabilities that
include local and remote loopbacks on theuplink interface and on each E1/T1
tributary link. A local loopback can also be
activated on the optional V.35 user port.

The V.35 interface supports internal,external, and loopback timing modes.
