Product Description

Dual Channel C37.94-to-T1 Fiber Service Unit

The new C37.94-to-T1 FSU is designed to convert any application devices with standard IEEE C37.94 compliant Short-Haul Fiber signals to an electrical T1 signal. The FSU allows for the conversion of up to two C37.94 output devices. The C37.94 fiber interface comes also with a non-standard Single-mode LED as an option for longer distances. The FSU is manufactured for wall/panel mounting, however, a rack mounting option will be available with 1RU (1.75”) 19” rack mount chassis.

The C37.94-to-T1 FSU is the perfect cost-effective solution to transport protective relaying devices or any industrial application devices reliably over an existing communications network, DS-1 Line or Leased T1 service.

C37.94 SHF Data Channels Over T1

  • Provides two independent IEEE C37.94 SHF Data Channels over industry standard DS1 signal

Easy Connection to Existing Network

  • Connect your protective relaying devices to a SONET or Multi-Service platform or Leased T1 line without the need for expensive channel banks or access gateway device

Cost-Effective Solution

  • Low cost solution to interface C37.94 compliant protective relaying equipment to existing communications network via T1 interface

C37.94 FIBER INTERFACES

  • Available in either Multi-mode or Single-mode fiber interface for either short or long distances

Rugged Design

  • Designed for harsh environments such as substations or exterior equipment buildings for wall mounting or with optional 1RU 19” rack mount chassis

User-Friendly Configuration

  • No software needed to configure the unit making it easy to configure through front panel switches
