Optimux - XLT1 provides a simple, flexible and cost-effective solution for transporting multiple T1 links and Ethernet at distances up to 60 km (36 miles).

Optimux - XLT1 integrates up to 12 T1 channels and up to four Ethernet LANs over a single fiber optic link. This provides an easily upgradable solution, flexible enough to meet the specific requirements of a broad range of applications.

The RAD Optimux-XLT1supports one fixed 10BaseT Ethernet port and three additional plug-in channel modules. Available channel modules are: Quad channel T1 10BaseT Ethernet.

Modules can be combined in various ways, ranging from four Ethernet ports to a single Ethernet port with up to 12 T1 channels.

Various optical interfaces are available: 850 nm for multimode fiber 1300 nm for single mode fiber 1300 and 1550 nm laser for extended range over single mode fiber.

Two Optimux - XLT1 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).

Where required, 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 switchover 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 6 Mbps and supports up to 10,000 addresses.

Optimux - XLT1 from RAD transmits each of the T1 channels independently, such that the clock of each T1 channel is independent.

To facilitate system diagnostics, Optimux - XLT1 features LED status indicators, AIS alarm generation, recognition and dry contact closure upon link failure. In addition, the Optimux - XLT1 setup, control and diagnostics can be performed via a supervisory port using an ASCII terminal. Telnet can also perform these operations via the Ethernet ports or a dedicated separate Ethernet management port.

The SNMP management application offers the following options: Java-based Web management running on Netscape or Microsoft Explorer RADview - PC running in a Windows environment RADview - HP for HPOV UNIX platforms.

Optimux - XLT1 is available as a compact 1U high unit for mounting in a 19" rack.

Multiplexer with built-in Ethernet port. Note: All channel modules should be ordered separately (see below).
 

*	Specify power supply AC for 115/230 VAC 48 for -48 VDC 24 for 24 VDC
R	Specify R for second redundant power supply (same type as first)
#+	Specify Link interface  (# for connector type, followed by + for optical wavelength)

 

#	ST for ST type connector SC for SC type connector FC for FC type connector
+	85 for 850 nm, multimode 13 for 1300 nm, single mode 13L for 1300 nm, single mode, laser diode 15L for 1550 nm, single mode, laser diode SF1 for transmit 1300 nm, receive 1550 nm SF2 for transmit 1550 nm, receive 1300 nm
Note:	for single fiber connection (WDM) one of the devices has to be ordered with SF1 interface and the other with SF2 interface.
