Optimux-134, Optimux-125
Fiber Multiplexers for 16 E1/T1 and Ethernet• Up to 16 E1/T1 links, full bandwidth 100 Mbps Ethernet traffic and high-speed
data multiplexed into fiber optic uplink• 34/25 Mbps or 134/125 Mbps operation modes• Single-mode, multimode, single-mode over single fiber, SFP-based interfaces• Range of up to 110 km (68 miles)• Optional additional hot-swappable power supply and uplink for redundancy

High-speed TDM andEthernet services
multiplexed over fiber

Optimux-134 and Optimux-125 provide asimple, flexible, and cost-effective solution
for transporting multiple E1/T1 links,
high-speed data and Ethernet over an E3
copper or fiber link, to distances of up to110 km (68 miles).
Each product features twolicense-activated operation modes:•In 34/25-Mbps mode, the units multiplex
up to 16 E1/T1 links, Ethernet traffic in
granularity of 8/6 Mbps and high-speed
data into a fiber optic or E3 uplink.

•In 134/125-Mbps mode, the units
multiplex up to 16 E1/T1 links and100 Mbps Ethernet traffic into afiber optic uplink.

The fiber optic link is available withsingle-mode, multimode, and single-mode
over single fiber interfaces.
In 34-Mbps device operation mode, theOptimux-134 uplink is compliant with E3
standards for coax interfaces and works
with 3rd party devices. The Optimux-134/125
uplink with fiber interfaces is proprietary
in both device operation modes.

Optimux-134, Optimux-125
Fiber Multiplexers for 16 E1/T1 and Ethernet

The unit multiplexes up to 16 E1/T1 links.
In 34/25-Mbps operation mode, the data
rate of the TDM ports can partially be
replaced (user-selectable) by the10/100BaseT user Ethernet traffic or by
an optional high-speed data V.35 interface(see Table 1).
UPLINK INTERFACES
Various interfaces (based on SFPtransceivers) are available for both theactive and the backup uplinks (see Table 1and Ordering Options):•

Electrical via coax (SMB) connector(34 Mbps mode operation only)•1310 nm short or long-haul laser and1550 nm long-haul laser interfaces forextended range over single-mode fiber•

Single fiber interface using WDM
technology, with the laser transmit
signal at a different wavelength thanthe receive signal (1310 nm and1550 nm).

UPLINK REDUNDANCY

V.35 INTERFACE

Upon link failure, the unit automaticallyswitches to an optional second uplink as abackup.

The Optimux devices can be supplied withone V.35 (2048/1544 kbps) channel that
replaces channel 16 by user activation.
The V.35 interface can only be used in
34/25-Mbps operation mode.

E1/T1 INTERFACE
Optimux-134/125 multiplexes 16 E1/T1
channels. The E1/T1 interfaces comply
with the ITU-T G.703. Line coding is HDB3
or B8ZS, respectively. A pair of LEDsmonitors loss-of-signal and AIS on each
E1/T1 receive line.
FAST ETHERNET INTERFACE
Optimux-134 and Optimux-125 feature
fast Ethernet ports enabling a full100-Mbps Ethernet connection in addition
to the capacity of the 16 E1/T1 channels.
The Optimux devices are supplied with a
10/100BaseT Ethernet USER port. This
port is activated via a software key. The
license can be purchased for 8/6-Mbps
granularity to work in 34/25-Mbps
operation mode, or for full bandwidth towork in 134/125-Mbps operation mode.

TIMINGThe Optimux devices transmit each E1/T1
channel separately so that the clock ofeach E1/T1 channel is independent.
Devices operating in 34/25 Mbps mode
support internal and loopback timing
modes. The 134/125-Mbps operationmode uses only internal timing.

TYPICAL APPLICATIONSDIAGNOSTICS

PHYSICAL

Private Networks
In private networks, Optimux-134/125
shares campus services such as Ethernet,
voice, data and video in P2P (Figure 1) andStar topologies over dark fiber.

Optimux features comprehensive test anddiagnostic capabilities that include local
and remote loopbacks on the uplinkinterface and on each E1/T1 port. A local
loopback is also supported on the optional
V.35 user port.

Optimux-125 is a compact, 1U-high unit.
Optimux-134 is available in a 1U-highversion with balanced E1 interface, andRJ-45 connectors, or a 2U-high version
with unbalanced E1 interface, and BNC or
IEC-169/13 connectors. The units with
IEC-169/13 connectors are equipped with
DIP switches to disconnect GND from theRx signal).

Optimux-134/125 establishes TDM andEthernet connectivity between the remotebranches and headquarters foreducational, financial, military sectors.
Traffic Backhaul Application
Optimux-134/125 transparently backhauls
TDM and Ethernet traffic over fiber orcoax uplink (see Figure 3).
Optimux devices connect cellular basestations to controllers. This solution meetsthe requirements of cellular backhaul
applications by providing TDM andEthernet traffic for CDMA and GSM
connectivity.
The Optimux units backhaul WiMAX traffic
from remote locations over dark fiber links
at a distance of up to 110 km (68.3 miles).

To ease system diagnostics, Optimux
features LED status indicators and AIS
alarm generation and recognition.
The devices also feature dry contact
closure upon link failure. An optional alarm
port is available with dry relay contacts for
major and minor alarms.
MANAGEMENTThe Optimux units can be configured andmonitored with a number of managementand diagnostic tools. An ASCII terminal
provides local management. Remotemanagement and diagnostics can be
performed via Telnet, a RAD Web-basedmanagement application or an
SNMP-based management application. The
products working in 34/25-Mbps
operation mode can be managed byRADview, RAD's SNMP-based management
application.

All the units can be mounted in a 19-inchrack.
POWER
The wide-range AC/DC power supply canbe connected to either an AC powersource (90 to 260 VAC), or a DC powersource (-40 to -125 VDC). The units canalso be ordered with a +24 VDC (20 to72 VDC) power supply.
A second power supply can be ordered for
power redundancy.

Uplink Interface (SFP)
Table 1 specifies the uplink interfaceoptions. To order uplink interface fromRAD, refer to the SFP Transceivers Data
Sheet at www.rad.com.
It is strongly recommended to order thisdevice with original RAD SFPs installed.
This will ensure that prior to shipping, RAD
has performed comprehensive functional
quality tests on the entire assembled unit,including the SFP devices.
Notes: 1. When ordering redundant SFPs, theymust be identical.
2. Single-fiber SFPs should always be used opposite
the reciprocal single fiber SFP. For example,SFPs-10A should be used opposite SFP-10B.
3. RAD cannot guarantee full compliance to productspecifications for units using non-RAD SFPs.
4. Optimux-134, Optimux-125 are supplied with
two SFP sockets, the transceivers must be orderedseparately.
