E3 Multiplexer

RAD’s Optimux-34 E3 optical line multiplexer multiplexes up to 16 E1 or T1 channels along with Fast Ethernet traffic over a single E3 link. Transmitting over single-mode fiber or multimode fiber as well as E3 coax, the Optimux-34 E3 optical line multiplexer can multiplex aggregate bandwidth up to 34 Mbps for distances up to 110 kilometers (69 miles). Flexible bandwidth management features enable the user to configure both the number of E1/T1 ports and Ethernet bandwidth simultaneously.  

 

The Optimux-34 E3 optical line multiplexer is used to extend E1/T1 lines from an SDH/SONET backbone as well as to fan out E1 lines from an E3 port in cellular backhaul applications over radio. In addition, the Optimux-34 E3 optical line multiplexer offers a low cost alternative to larger and more costly add-drop multiplexers or DACs units.

 

As an option, the Optimux-34 E3 optical line multiplexer can be equipped with an SFP transceiver, redundant links and power supplies, ensuring transmission reliability and fail-safe.

• Easy LAN connectivity

• Flexible bandwidth management enabling the addition of low cost Ethernet bandwidth instead of E1 links

• Offers cost-effective support of new services with minimum investment

The Optimux-34 E3 optical line multiplexer provides a simple and cost-effective solution for transporting multiple E1 or T1 links, as well as data and Ethernet, for distances up to 110 km (69 miles).

Optimux-34 E3 optical line multiplexer supports up to 16 E1 or T1 channels. A single 10/100BaseT Ethernet user port is optional. The bandwidth available for the Ethernet port can be adjusted by the user in gradations of 8 Mbps. The configuration options are:

- 16 E1/T1 only

- 12 E1 and 8.448 Mbps for Ethernet

- 12 T1 and 6.176 Mbps for Ethernet

- Eight E1 and 16.893 Mbps for Ethernet

- Eight T1 and 12.352 Mbps for Ethernet

- Four E1 and 25.334 Mbps for Ethernet

- Four T1 and 18.528 Mbps for Ethernet

- 32 Mbps for Ethernet only (E1 version)

- 25 Mbps for Ethernet only (T1 version)

 

The main link interface of the Optimux-34 E1 version can be either a standard coax E3 interface or a fiber optic interface. In the Optimux-34 T1 version, only a fiber interface is available.

 

The following optical interfaces are available:

- 1310 nm and 1550 nm laser for extended range over single mode fiber

- 1310 nm and 1550 nm long haul for extended range over single mode fiber

- Single fiber option

Ethernet transmission utilizes a single integrated 10/100BaseT LAN port. The Ethernet port can operate in half or full duplex mode, and supports auto-negotiation and transparent VLAN forwarding. IEEE 802.3x flow control and backpressure are also supported.

 

The Optimux-34 offers redundant power supply and secondary link options, enhancing system reliability. The optional secondary link provides backup using automatic switchover upon main link failure.

 

The Optimux-34 E3 optical line multiplexer devices transmit each of the E1 or T1 tributary channels independently. The E1 interface can be 75Ω unbalanced or 120Ω balanced. The T1 interface is 100Ω balanced.

 

The E3 interface clock in the Optimux-34 E1 version can be locked onto an external station clock. To facilitate system diagnostics, all products feature LED status indicators, AIS alarm generation, recognition and 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 or Web terminal, or from an SNMP management station via the Ethernet port or the dedicated management port (Ethernet or RS-232).

 

The SNMP management application offers:

- RADview for Windows environment

- RADview for HP OpenView UNIX platforms

All products are available as compact 1U-high units for mounting in a 19-inch rack.
