The AQ7275 is one of the best selling OTDRs in the world. Model lineup has been expanded to a total of 9 models to choose from with a dynamic range of up to 45dB . Wavelength capability spans from 850nm (MMF) to 1650nm (SMF). An impressive 0.8m event dead zone makes this model an excellent choice for FTTH and metro, core networks.
Enhancements include a PON option allowing accurate event analysis after a 1×32 splitter with significantly reduced undershoot effects. Also unique to the industry is a built-in section of launch fiber to eliminate the need for a separate launch box.
Latest standard features includes the convenient capability to display a fiber connector inspection probe using one of the unit's standard USB I/O ports.
Yokogawa's OTDR has improved to suit your changing needs:
- Wide Range of Modules Available
- Enhanced support of FTTH to Metro, Core Network
- High Dynamic Range (45dB)
- Short Dead Zone (0.8 m)
- Optional built in Dummy Fiber

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. |
Meets a broad range of measurement needs from FTTH to Metro, Core network.
Event Dead Zone 0.8 m
| 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. |
 |
High Dynamic Range up to 43 dB (45dB typical)
| 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. |  |
Quick Startup within 10 Seconds
Now measurements can be started quickly upon arrival at the site. 10 seconds to power-up from completely OFF to fully ON! With such a fast power-up time, battery life can be extended by turning the power off while not in use at the job site without any concern about the power-up time when the next job is ready. It’s ready when you’re ready!
