Product Description

Symmetric High Bitrate DSL Fiber Service Unit

The new SHDSL-FSU (Symmetric High bitrate DSL Fiber Service Unit) is standalone device that serves as a media converter between electrical ITU-T G991.2 SHDSL signals and optical IEEE C37.94 fiber protocol signals. It is designed to enable modern C37.94 equipped application devices to communicate over legacy copper pilot wire infrastructure. The C37.94 fiber interface also comes with a non-standard single-mode LED as an option for longer distances between the application device and the FSU.

The C37.94-to-SHDSL FSU is the perfect cost-effective solution in a single stand-alone platform to transport protective relaying devices or any industrial devices reliably over existing long copper lines. The FSU unit is capable of switching or distributing SHF/TDM payload between individual HDSL ports.

C37.94 SHF Data Channels Over SHDSL

  • Provides single IEEE C37.94 SHF Data Channel over up to four industry standard SHDSL signals.

Easy Connection to Existing Copper Lines

  • Connect your protective relaying devices over existing long copper lines without the need for expensive communications devices.

Performance

  • The SHDSL signals can be conveyed over a single twisted pair, or 2 or 4 pairs (M-pair working). Using multiple pairs as oppose to single pair improve performance by increasing reach and payload bandwidth.

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.

User-Friendly Configuration

  • User-friendly configuration using pre-programmed profiles DIP-switches, or the Windows-based user interface.
