The FOT-700 Fiber-Optic Tester can be configured for a variety of test applications including multimode fiber LANs, singlemode telephone networks, and fiber-optic CATV systems. An automatic dual-wavelength recognition feature eliminates testing problems caused by erroneous wavelength selection. Up to 1000 dual-wavelength readings can be stored in the FOT-700, and a built-in RS-232 port simplifies data downloads for analysis and reports in EXFO's ToolBox software.
The FOT-700 supports L-band (1570 to 1610 nm) testing. Measuring optical loss at 1625 nm provides out-of-band testing at a wavelength that corresponds to the worst-case attenuation for signals transmitted in the L-band. Testing at 1625 nm is important because telecommunications service providers are now using the L-band window to increase transmission capacity beyond the 1550 nm window.
