Optimux-1553
Fiber Multiplexers for 3 E3/T3 over STM-1/OC-3
• STM-1/OC-3 terminal multiplexer for grooming high-order legacy traffic (TDM)
over SDH/SONET networks
• Up to three E3 or T3 data channels multiplexed using a single hot-swappable card
Any Traffic over Fiber
• Optional 1+1 redundant network interface (single-ended MSP/APS); 1+1
protection of E3/T3 tributaries and power supply for complete carrier-class
hardware redundancy and serviceability
• Plug-and-play operability
Optimux-1553 is a unique STM-1/OC-3
terminal multiplexer for transport of
high-order legacy PDH traffic over
SDH/SONET. Three E3 or T3 tributary
channels are mapped into a standard
channelized STM-1/OC-3 uplink, extending
the local loop up to 80 km (50 miles),
while creating a transmission layer fully
compatible with regional and national
SDH/SONET networks.
The Access Company
Optimux-1553
Fiber Multiplexers for 3 E3/T3 over STM-1/OC-3
Power supply and uplink modules in
Optimux-1553 can be backed up and are
field-serviceable. Uplink 1+1 single-ended
MPS/APS redundancy is supported in
compliance with the G.841 and
GR-253-CORE standards. Power supplies
are also backed up and are
hot-swappable. These features ensure
that Optimux-1553 has no single point of
failure, and is fully compatible with carrier
class requirements.
Optimux-1553 is available with either
coaxial or fiber optic short/long haul uplink
interfaces.
Setup, control, status monitoring, and
diagnostics information can be performed
using one of the following methods:
The unit provides high availability, and
high-quality performance monitoring of
the traffic path, from the SDH/SONET
network to the customer premises.
•
ASCII terminal connected to the DB-9
control port
•
Telnet host via the dedicated Ethernet
port
The simplicity, compact size and low
power consumption of Optimux-1553
allow easy rack installation on both
customer premises and telecommunication
facilities.
•
Network management station (NMS)
running RADview-EMS, RAD’s
client-server CORBA-based SNMP
network management application. NMS
is connected via the dedicated
Ethernet port
•
RAD’s Web-based remote access
terminal application, via the dedicated
Ethernet port
•
TFTP for software update and remote
configuration, via the dedicated
Ethernet port.

Notes: 1. For copper cables (coax interface), a range of 135m is attainable when using RG-59 B/U (at 78 MHz, in accordance with the square root frequency law).
2. The ranges specified above were calculated according to the following typical attenuation rates (with a 3 dB margin):
ƒ 3.5 dB/km for 850 nm multimode
ƒ 0.4 dB/km for 1310 nm single mode
