Professional Data Management

Analyze extensive data with the optional RS-232 interface. This option comes with all the necessary applications to download, view, export or print your data in table or graph form. Develop your own programs and control the meter from a remote location with the control codes. Tailor the FOT-90A to your testing needs.

Signal Detection at 2 kHz

Accelerate fiber identification with this handy feature by locating fibers carrying a 2 kHz signal, even through a 3 mm jacket. A special adapter facilitates this operation while ensuring that you don’t overbend the fiber.


Three-Way Powering

The FOT-90A features three complementary power sources for extended operation. When the rechargeable NiCd battery runs low, the unit automatically switches to the 9 V alkaline battery backup. An AC adapter/charger is also supplied for continuous operation.

An Ideal Complement

Temporarily connect unterminated fibers directly to the FOT-90A with EXFO bare fiber adapters. These adapters are user-friendly, will not bend or put excessive pressure on the fiber and offer the highest precision available on the market today.
