Handheld OTDRs

Two new testers designed specifically for the system maintenance of passive optical networks (PONs) have been added to the Yokogawa AQ1200 Series of handheld optical time-domain reflectometers (OTDRs).

The new AQ1200B and AQ1200C OTDR carry out measurements at the maintenance wavelengths of 1625 nm and 1650 nm, respectively, and are optimised for in-service PON testing of FTTx access networks. Each single-wavelength model incorporates a 1310/1550nm cut filter to reject unwanted in-service signals, and will carry out accurate measurement through high-port-count (1 x 32 or 1 x 64) splitters.

Options include a choice of three different optical power meters, including one for PON applications, a 1625 or 1650nm light source function, a 650nm (red) laser for visual fibre inspection, and an Ethernet PING test function.
