FTE7800 36/35dB OTDR with CWDM Channel Analyzer-OCA

The FTE-7800 is a true multi-tasker with all the features and applications found in much higher priced test equipment. This is a dual wavelength OTDR, Eight Channel CWDM Channel Analyzer, Stable Light Source, Broadband Power Meter, Visual Fault Locator and Video Inspections Scope all in one handheld unit weighing just 2 pounds.

The OTDR has a 36/34dB (1310/1550) dynamic range and a short 1 meter dead zone. The Channel Analyzer has a 1/4 second refresh rate while scanning the top eight CWDM channels on the ITU grid (1471-1611nm). For flexibility the channel numbers are selected in wavelength or frequency and the information is displayed in graph and table mode on the 4 inch, high brightness color LCD. This unit can store up to ~500 OTDR traces, 1,000 CWDM scans, 10,000 LTS measurements and 50 Video Scope images.

Tests can be downloaded via the USB PC or USB flash ports and documented with the included Cert-Soft certification software to create professional reports. The video scope helps ensure connector cleanliness and integrity prior to connecting to the fiber optic port. The onboard Help system guides new users through operation and assists in setting test parameters. The FTE-7800 is housed in a rugged metal enclosure with a robust protective boot.
