• Optimux-XLE1 provides a simple, flexible and cost-effective solution for transporting multiple E1 links and Ethernet at distances up to 110 km (69 miles). Two versions of the multiplexer are available: modular and non-modular.

Modular Version

• The modular version of the Optimux-XLE1 integrates up to 12 E1 channels or up to four Ethernet LANs over a single E3 link. This provides an easily upgradable solution, flexible enough to meet the specific requirements of a broad range of applications.

• The modular version supports one fixed 10BaseT Ethernet port and three additional plug-in channel modules. Available channel modules are:

• Dual channel E1
• Quad channel E1
• 10BaseT Ethernet.

• Modules can be combined in various ways, ranging from four Ethernet ports to a single Ethernet port with up to 12 E1 channels.

Non-Modular Version

• The non-modular version supports 16 E1 channels, and is designed for applications requiring the full E3 bandwidth for multiple E1 connectivity.

General

• Various optical interfaces are available:

• 850 nm for multimode fiber
• 1300 nm for single or multi mode fiber
• 1300 nm and 1550 nm laser diode, long haul laser or WDM laser for extended range over single mode fiber

• Two Optimux-XLE1 units can be connected over a single fiber (SF) using the WDM technology. (The transmit signal is at a different wavelength than the receive signal.)

• All critical components can be automatically backed up. This ensures there is no single point of failure. An optional second link provides backup, using automatic switch-over upon link failure. An optional second power supply provides power redundancy and fail-safe operation.

• Ethernet data is transmitted using a built-in bridging function. The bridge operates at "almost wire-speed" (8.4 Mbps) and supports up to 10,000 addresses.

• Optimux-XLE1 transmits each of the E1 channels independently, such that the clock of each E1 channel is independent. The E1 interface can be 75( unbalanced or 120( balanced.

• A single station clock module can be ordered to facilitate external clocking.

• To facilitate system diagnostics, Optimux-XLE1 features LED status indicators, AIS alarm generation, recognition and dry contact closure upon link failure. In addition, the Optimux-XLE1 setup, control and diagnostics can be performed via:

• A supervisory port using an ASCII terminal
• An SNMP management station via the Ethernet ports
• A dedicated separate Ethernet management port.

• The SNMP management application offers the following options:

• RADview-PC/TDM running in a Windows environment; or
• RADview-HPOV/TDM for UNIX platforms.

• Optimux-XLE1 is available as a compact 1U high unit for mounting in a 19" rack.

• It is possible to add a redundant link to an existing unit or to replace the link modules by ordering E3 coax, multimode, or single mode AMC-101 modules.
