Handheld OTDRs for network maintenance

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 1625nm and 1650nm, 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 1625nm or 1650nm light source function, a 650nm (red) laser for visual fibre inspection, and an Ethernet PING test function.
