Simple, space-saving & cost-effective DS3 or Ethernet extension and delivery over optical fibre

Deliver T3, E3, STS-1 or Ethernet signals quickly and cost-effectively with Telect's optical-electrical converters. Choices include T3 or Ethernet modules, protected T3 module sets for additional redundancy, and single-fibre T3 modules that send and receive signals through a single connector. 

Wall-mount systems include one module and a mounting bracket, and require a power supply (see below) if a 48V source is not readily available. 

Features 

  • Deliver DS3s 50km and Ethernet 30km over single mode fibre
  • Extend cross-connects across large offices, campuses, buildings, or in building risers
  • Rapidly deploy DS3 or Ethernet service to remote customers
  • Extend DSL service to additional customers quickly and simply
  • 1RU chassis provides advanced functionality in minimal space
  • Wall mount systems include one module and mounting bracket
  • Mounting brackets suitable for EIA/WECO
