735041-New

4-wavelength model for installation and maintenance of LAN and FTTH with support for both multimode and single mode fiber. Dynamic range is specified when measuring 50GI fiber.

Accompanying the rapid proliferation of FTTH is a growing need for detection of reflective events arising from short distance mechanical connections. The AQ7275’s short event dead zone enables detection of closely spaced events in cables installed in offices and customer premises.

The new High Dynamic range model (735034) can achieve the dynamic range of 40 dB. This high dynamic range is effective in measuring a transmission line consisting of long fiber cables and a splitter with a large loss.
