Media Converters
|  |
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-fiber 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 50 km and Ethernet 30 km over single mode fiber
- 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
