Optical Time Domain Reflectometer (OTDR)

Launched in September 2012 at ECOC this is a world class OTDR that does NOT require mirrors or reflectors.

 

  • A revoutionary Central Office OTDR that can see through 1:128 splitters without reflectors or mirrors.
  • Locates faults in PON networks in less than 1 minute
  • Eliminates manual fault finding processes
  • Simple to use, pass / fail or detailed fault analysis
  • Identifies all customer affected by a fault

This OTDR features UTEL's revolutionary Advanced Reflection Detection technology. This enables it to reliably detect ONT reflections through 128 splits without needing test wavelength reflectors to be fitted at the ONTs. The OTDR operates at 1650nm and incorporates 1310/1490/1550 nm cut-off filtering enabling the real time testing of live PON networks. The OTDR is also fitted with a UTEL Optical Control Bus port which enables it to directly control multiple Optical Test Access Switch modules.

Optical Switch

The roll out of Optical Fibre networks has introduced a new testing dilemma - or lack of test options.

We are pleased to be involved with the new range of Optical Test products being launched this year by UTEL.

These include a fully specified Optical Time-Domain Reflectometer (OTDR), an Optical Test Access Switch and an intelligent Optical Distribution Frame (ODF).

A fully configurable solution where switches can be set up an a cascade fashion to build a switch as large as required.
