FIBER MULTIPLEXERS

Optimux-45, Optimux-45L

Multiplexers for 21E1/28T1 over Fiber or T3

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,

AIS alarm generation and recognition, as well as

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.

Management options

The Optimux-45 and Optimux-45L feature

flexible management capabilities, including local

management via an ASCII terminal (RS-232). In

addition, remote management can be performed

either inband using the network or user ports,

or out-of-band using a dedicated management

port.

Advanced FCAPS (Fault, Configuration,

Administration, Performance, Security) and

diagnostic tools are provided by RADview-EMS,

RAD’s carrier-class element management

system, via an SNMP-based GUI. When working

in ring topology (Optimux-45), the application is

managed via RADview-EMS.

The Optimux-45 and Optimux-45L also support

a variety of access protocols, including CLI over

Telnet, SNMP, Web server, and TFTP.

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.

• Cross connect capabilities for drop-and-

insert and ring applications

• Multiplexes up to 21 E1 or 28 T1

channels over a single T3 (45 Mbps) or

fiber link

• Simultaneous multiplexing of E1 and T1

channels (according to G.747 standard

recommendations)

• T3 transmission over coax, fiber optic

• Range up to 110 km (68 miles)

• Optional redundant power supply

• Full management support for fault,

configuration, performance, and

security via RADview – RAD's network

management system

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, Optimux-45

provides a complete path protection mechanism

that prevents any service failure, even if a fiber link

is damaged or disconnected. In addition, the

Optimux-45 can provide ring connectivity over

microwave radio links.

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

100Ω), up to 21 E1 channels (balanced

120Ω) or mixed E1 and T1 channels

• Unbalanced version has up to 21 mini-BNC

connectors and supports up to 21 E1 channels

(unbalanced 75Ω)

The Optimux-45L is a low cost version of the

Optimux-45 with Telco connectors as the user
