Optimux-4E1, Optimux-4T1

E1/T1 Optical Line Multiplexers

Product Summary
Optical line multiplexers are cost-effective devices for extending multiple voice and data circuits over fiber optic links. RAD’s Optimux-4E1 optical line multiplexer and Optimux-4T1 optical line multiplexer can transmit four E1 channels or four T1 channels, respectively, up to 120 kilometers (75 miles) over optical fiber. Typical users of optical line multiplexing equipment include transportation and utility companies, Internet service providers (ISPs) and carriers extending data and voice from SDH/SONET networks or backhauling cellular traffic.

As an option, the Optimux-4E1 multiplexer and Optimux-4T1 optical line multiplexers can be equipped with redundant links and power supplies, ensuring transmission reliability and fail-safe operations.

Benefits

  • Low cost, long distance E1/T1 connectivity
  • Large range of optical options available; can be used in any fiber optic network
  • Compact size reduces co-location costs
  • Single fiber (WDM) option reduces fiber optic cable costs

  • System diagnostics include LED indicators, dry contact and recognition alarms, and AIS alarm generation
  • Setup, control, and diagnostics can be performed via Telnet, ASCII, SNMP management, and the RADview management system
  • Available as a standalone or inserted as a module in an LRS-24 chassis (Optimux-4T1 only)

Further Product Information

Multiple voice and data circuits over one link

The Optimux-4E1 and Optimux-4T1 optical line multiplexers combine four E1 links or four T1 links (respectively) over a fiber optic link. A pair of Optimux-4E1 or Optimux-4T1 units offers simple and low-cost connectivity for four E1 or T1 channels at distances up to 110 km (69 miles).

An optional secondary link provides backup using automatic switchover upon link failure, and an optional secondary power supply provides power redundancy and fail-safe operation.

Reliable E1/T1 transmission

The Optimux optical line multiplexers transmit each of the E1 or T1 signals independently, so that the clock of each E1 or T1 channel is independent of the clock of any other E1 or T1 channel. The E1 interface can be 75Ω unbalanced or 120Ω balanced. The T1 interface is 100Ω balanced.

Various optical interfaces are available:

  1. 850 nm for use with multimode fiber
  2. 1310 nm for use with multimode fiber
  3. 1310 nm or 1550 nm laser for extended range over single mode fiber
  4. single fiber option

Also available are the card versions with central SNMP management, for mounting in the rack. These provide a compact, cost effective central solution working opposite standalone Optimux-4E1 and Optimux-4T1 optical line multiplexers.

Configuration, monitoring and maintenance operations can be performed via a supervisory port, using either an ASCII terminal, Telnet host, Web terminal or an SNMP management station. This is done via a dedicated Ethernet port in the Optimux-4E1 and Optimux-4T1.

The SNMP management supports:
- RADview for PC
- RADview for HP OpenView UNIX platforms

To facilitate system diagnostics, the Optimux optical line multiplexers feature LED status indicators, AIS alarm generation, recognition and dry contact closure upon link failure.
