Fiber identifiers are handheld fiber optic test instruments for detecting optical signals transmitted through a fiber without disrupting live traffic. They are used in installation, maintenance, rerouting, or restoration to isolate a specific fiber.

The OFI-400 is a rugged, hand-held and easy-to-use fiber optic test instrument designed to detect and measure the core power levels of optical signals on single-mode optical fiber without disrupting raffic on that fiber. The OFI 400 C is designed and calibrated for use with 250µm, 900µm, ribbon, 2 mm and 3mm jacketed optical fibers.

 

The Noyes Fiber OFI 400 Optical Fiber Identifier detects signals transmitted through singlemode fiber without disrupting traffic. This fiber optic tester features a two-position head, multiple tone signal detection and set reference. Measure/display fiber core or relative power on a backlit LCD during installation, maintenance, rerouting or restoration.
