Optimux-45,
Optimux-45L
21 E1 or 28 T1 over
T3 or Fiber Multiplexers
Optimux-45 and Optimux-45L are manageable
multiplexers that provide a highly cost-effective
and simple solution for transporting multiple E1
and T1 links, as well as a combination of E1 and
T1 (according to ITU G.747), over a standard T3
electrical signal or fiber link. They provide
flexible solutions to meet the specific
requirements of a broad range of applications.
The Optimux-45 is an add and drop multiplexer,
enabling it to support a wide range of
applications. When deployed in a ring
application, the Optimux-45 provides a complete
path protection mechanism that prevents any
service failure, even if a fiber link is damaged or
disconnected.
Optimized for E1/T1 line quantity
To improve the price/performance ratio of the
product, partial assemblies with four, eight or
12 ports are available, reducing the price
significantly in nodes requiring only a small
number of E1/T1 lines.
The Optimux-45 supports both balanced and
unbalanced interfaces:
• Balanced version has RJ-45 connectors and
supports up to 28 T1 channels (balanced
100 Ω), up to 21 E1 channels (balanced
120 Ω) or mixed E1 and T1 channels
• Unbalanced version has up to 21
mini-BNC connectors and supports up to 21
E1 channels (unbalanced 75 Ω)
The Optimux-45L is a low cost version of the
Optimux-45 with Telco connectors as the user
interface. The Optimux-45L is optimized for
point-to-point or point-to-network applications
only. This unit provides low cost connectivity of
21 E1 or 28 T1 lines or any combination of E1
and T1.
All versions are non-modular and offer
redundant power supply, enhancing system
reliability. In addition, an optional secondary link
provides backup using automatic switchover
upon main link failure.
Supports both electrical and optical
interfaces
The products’ main link supports both electrical
and optical interface options. The electrical
interface has BNC connectors in conformance
with G.703 standards.
The optical interface supports the following
options:
• 850 nm for multimode fiber
• 1310 nm for multimode fiber
• 1310 nm and 1550 nm laser for extended
range over single mode fiber
• 1310 nm and 1550 nm long haul
• Single fiber option (WDM)
• Single fiber/wavelength option
To facilitate system diagnostics, the Optimux-45
and Optimux-45L feature LED status indicators
as well as AIS alarm generation, and recognition
and dry contact closure upon link failure. In
addition, setup, control and diagnostics can be
performed through a supervisory port using an
ASCII terminal, Telnet host, Web terminal, or
from an SNMP management station via a
dedicated management port (Ethernet or
RS-232).
Standards Compliance
The Optimux-45 and Optimux-45L conform to
ITU G.703, G.747, G.823, G.824, ANSI T1.107,
ANSI T1.404, RFC 3895, and RFC 3896.
The SNMP management application offers:
• RADview-PC running in a Windows
environment
• RADview-HPOV for HP OpenView UNIX
platforms
The T3 link via an optional clock interface can
be locked onto an external station clock.
The products support various performance
statistics on the E1, T1 and T3 lines.
The Optimux-45 and Optimux-45L are available
as compact 1U-high units for mounting in a
19-inch rack.
• Multiplexes up to 21 E1 or 28 T1
channels over a single T3 (45 Mbps) or
fiber link
• Cross connect capabilities for drop-and-
insert and ring applications
(Optimux-45 only)
• Simultaneous multiplexing of E1 and T1
channels (according to G.747 standard
recommendations)
• T3 transmission over coax, fiber optic
or wireless
• Multimode or single mode fiber
• Single fiber (WDM) and single
fiber/wavelength option
• Range up to 110 km (69 miles)
• Optional secondary link provides
automatic backup
• Optional redundant power supply
• Full management support (SNMP and
Telnet) by RADview ASCII terminal, Web
terminal or Telnet host
• E3, T1 and T3 statistical support
