Description
Fully compliant Optimux-45 M13 multiplexer integrates up to 28 T1, 21 E1, or combinations of T1 and E1 circuits (according to ITU G.747) over a standard T3 electrical signal or fiber link. The Optimux-45L M13 multiplexer is a low cost version using Telco clamps as the user interface.
The Optimux-45 M13 multiplexer can support a wide range of applications and topologies, including campus ring, drop-and-insert for cellular backhaul, point-to-point over wireless links, and point-to-point over SDH/SONET. The maximum range is 110 kilometers (69 miles). In addition both the Optimux-45 M13 multiplexer and Optimux-45L M13 multiplexer can serve as cost-effective alternatives to high-speed ADMs or large DACs. Alternatively, the Optimux-45 and Optimux-45L can be used in conjunction with equipment such as large DACs, which do not support tributaries lower than STM-1/OC-3.
Both the Optimux-45 M13 multiplexer and Optimux-45L M13 multiplexer have a redundant power supply, enhancing system security. An optional secondary link provides automatic backup, ensuring transmission reliability.
Further Product Information
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.
Wide range of applications and optionsThe Optimux-45 M13 multiplexer has internal cross connect capabilities that enable 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. In order to improve the price/performance ratio of the product, partial assemblies with four, eight or 12 ports are available, thus reducing the price significantly in nodes where only a small number of E1/T1 lines are needed.
The Optimux-45 M13 multiplexer 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 M13 multiplexer is a low cost version of the Optimux-45 with Telco (Champ) 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 interfacesThe 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 haulsingle fiber option (WDM)
- single fiber/wavelength option
Advanced management, control and diagnosticsTo facilitate system diagnostics, the Optimux-45 and Optimux-45L feature LED status indicators as well as AIS alarm generation, recognition and dry contact closure upon link failure. In addition, the Optimux-45 and Optimux-45L M13 multiplexers 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).
The SNMP management application offers:
- RADview-PC/TDM running in a Windows environment
- RADview-HPOV/TDM 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 T3, T1 and E1 lines.
The Optimux-45 and Optimux-45L M13 multiplexers are available as compact 1U-high units for mounting in a 19" rack.
