907 Plus Media Converter

FIBER OPTIC MEDIA CONVERTERS

The new 907Plus is a singlemode multiplexer that extends the capabilities of standard 907 motherboards with an added video channel, galvanically isolated data channels, and a comprehensive, integrated diagnostics network. System expansion is even easier with a rapidly growing family of compatible daughtercards and media converters. A diagnostics add-on card is now available that offers end-to-end performance monitoring and identification for multi-card systems via an Ethernet connection at the console and Graphical User Interface (GUI) software.

Expansion cards may be stacked on the motherboard to add up to 48 data channels in a variety of formats, including RS-232, RS-485 / 422, TTL, Ethernet, CANBus, analog sonar, hydrophone, audio, and Tritech ARCNET. Depending on transceiver options, optical power budgets are typically 20-26 dB with 10 km or more of singlemode fiber.

Features

  • Available as a pressure tolerant model, rated for 3000 or 6000 PSI
  • Ethernet diagnostics daughtercard available with standard Graphical User Interface (GUI) or Microsoft .NET library for customer GUI development
  • Replaceable SFP transceiver with built-in diagnostics
  • Higher data bandwidth available versus standard 907
  • I2C bus supports diagnostic communications with expansion cards and media converters
  • Galvanically isolated serial data channels

Benefits

  • Isolated data channels provide more robust interface to external equipment
  • Supports a wide range of optical options including CWDM for combining up to 4 separate 907 systems on a single fiber or several 907s with media converters
  • No motherboard data channels are disabled when expansion cards are added
  • Diagnostics monitoring allows early identification of potential problems
