The Fast Light OTDR

As an R&D organisation, UTEL has a reputation for stretching the technical envelope of what is deemed possible. In the development of our OTDR we have applied the latest micro-electronic and laser technology and have succeeded in creating a truly revolutionary measurement platform with a 43 dB dynamic range. The basic OTDR trace is further enhanced and digitally cleaned of noise using advanced mathematical processing techniques. This enables the Fast Light OTDR to clearly see reflections, which until now have been buried in the noise floor of our competitors OTDRs.

The Fast Light OTDR probe has been specifically developed to enable the cost effective central office testing of fibre PONs. The probe utilises a revolutionary new high performance OTDR which controls an associated Optical Test Access Switch.

Specially designed and optimised for Central Office based testing of FTTx and PON/GPON fibre Networks.
