Noyes C850 from AFL Telecommunications is a full-featured QUAD OTDR in a compact case with a large transflective touch screen display suitable for both indoor and outdoor operation. The C850 offers built-in auto test functionality when used with another C850 or the C840 QUAD Certification Tester. The C850 features MM and SM OTDR capabilities, both single-mode and multimode Optical Light Sources (OLS), Visual Fault Locator (VFL, 650 nm), and an Optical Power Meter (OPM). As an OTDR, the C850 supports Full Auto, Expert (manual) and Real-Time test modes, simultaneous dual and single wavelength testing, and Event and Pass.

Two C850s or a C840 Tester and C850 can be used together to perform Tier 1 dual wavelength MM (850/1300 nm) and SM (1310/1550 nm) auto tests of one or two fibers in one or both directions; and measure both loss and length of the fibers and compare to industry standards (TIA/ISO/EN), applications and user-defined thresholds values to certify the fibers. The user may test two fibers at two wavelengths bi-directionally and store the results into the main unit. Featuring rich file naming, the Job setup wizard allows the user to define both the cable and fiber end locations, creating easily identifiable trace files, which are managed into Job and Cable folders.
