Optimux-4E1L ( OP-4E1L ) multiplexer from RAD
Optimux-4E1L ( OP-4E1L ) is a multiplexer that combines up to four E1 channels over a single coax or fiber optic E2 link. A pair of Optimux-4E1L units offers simple and low-cost connectivity of four E1 channels at distances of up to 120 km/74 miles (see Figure 2).
Optimux-4E1L ( OP-4E1L ) from RAD offers various optical interfaces:
850 nm for multimode fiber LED
1310 nm for multi mode fiber LED
1310 and 1550 nm laser for extended range over single mode fiber
1310 and 1550 nm laser for single fiber – WDM (Wavelength Division Multiplexing) operation.
1310 nm laser for single fiber/single wavelength operation
Optimux-4E1L ( OP-4E1L ) transmits each of the E1 channels independently, such that the clock of each E1 channel is independent of the clock of any other E1 channel. The E1 interface can be 75Ω unbalanced or 120Ω balanced (see Ordering secion of product data sheet).
Optimux-4E1L ( OP-4E1L ) can operate opposite an Optimux-4E1 standalone unit or an OP-4E1 card for the LRS-24 19-inch rack with central SNMP management. This option provides a compact, cost effective central solution (see Figure 1).
To facilitate system diagnostics, Optimux-4E1L ( OP-4E1L ) features LED status indicators, AIS alarm generation, recognition and dry contact closure upon link failure. Configuration, monitoring and maintenance can be performed using an ASCII terminal or a SLIP connection to an SNMP management station.
Optimux-4E1L ( OP-4E1L ) SNMP management supports:
RADview-PC running on PC/Windows
RADview-HPOV running on an HP OpenView UNIX platform.
Optimux-4E1L is available as a compact 1U high half 19-inch unit, which can be mounted in a 19-inch rack.
