The FX80 power meter is designed to test passive optical networks (PON). It is used to
simultaneously measure all optical signal levels between the Optical Line Terminal (OLT) and
the Optical Network Unit/Terminal (ONU/ONT) on Gigabit B/E/GPON type networks. It can be
connected onto the PON network at any available access point along the Optical Distribution
Network (ODN). The access point can be at the OLT (central office - CO, head end or subheadend or remote hut), Fiber Distribution Point (FDP 1 or 2/splitter (if connectorized) or at
the ONU/ONT (customer premises - CP).ÊFigure A typical passive optical network (PON) with
possible points of measurement shows a typical passive optical network (PON) with the three
possible locations for measurement].
The unit passively monitors 1310, 1490 and the optional 1550 nm RF video downstream and
upstream PON optical power levels for compliance to standards. The measurement results
can be transfered to a PC or uploaded to the cloud using a Fiberizer Cloud account.
The operator is assumed to have received basic training in fiber optics and related testing
and measurement practices.
