Yokogawa has extended the capabilities of its AQ7280 series optical time-domain reflectometer (OTDR) with the introduction of three new modules. The modules widen the application range of the fiber-optic test system.

The three modules include:

  1. The AQ7283E, for OTDR measurements at 1625 nm over traffic-bearing fibers. The module leverages a filter that eliminates the shorter wavelengths used for data transmission so they do not interfere with OTDR testing.
  2. The AQ7283J for testing at the 1383-nm water-peak of optical fibers aims to meet the needs of fiber-optic cable manufacturers and technicians who want to determine if deployed fibers will support CWDM, for example, in cable television applications. Low-OH fiber is better suited to CWDM, Yokogawa points out.
  3. The AQ7282G targets fiber-to-the-home (FTTH) network installations that require measurement at 1490 nm. The module can measure three wavelengths – 1310, 1490, and 1550 nm – via a single port. Yokogawa positions the AQ7282G as a cost-effective alternative to the four-wavelength AQ7283K module.

The company also has released an upgrade for its AQ7282M module, which can now be equipped with a multi-mode stabilized light source that emits at 850 and 1300 nm for an extended range of tests.
