Fibre OTDR

Overview

The Fast Light OTDR probe has been specifically developed to enable the cost effective central office testing

of fibre cable systems both point to point and point to Multipoint (PON's).

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 technology and have succeeded in creating a truly revolutionary

measurement platform with a high 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, from ONT's on PON network. The OTDR with its high dynamic range is ideal for

monitoring long distances fibres , providing clear accurate fault locations , plus also dynamic degradation

information to allow preventative maintenance.
