Optical Fiber Identifiers

AFL’s optical fiber identifiers (OFIs) are rugged, easy-to-use test instruments that detect the presence of signals on optical fibers. An OFI is an important tool for field technicians – assuring that live fibers are not disconnected and providing the ability to trace fibers from end to end.

OFIs are simply clamped onto a fiber, where they induce a safe macro-bend and allow a small amount of light to escape. Units use this light to detect the presence of network traffic, test tones or CW signals and indicate the direction of the signal.

AFL offers several OFIs in order to meet the needs of every customer. Our newest OFIs (OFI-BI and OFI-BIPM) are some of the most sensitive units on the market, making it the ideal choice for detecting any type of single-mode fiber – including bend insensitive SM fibers.

Our full featured OFI includes a touch screen, positive stop trigger and several easy to select options. These identifier can be used with multimode or single-mode fibers – including bend insensitive fiber, bare fibers, ribbon fiber and up to 3mm jacketed fiber. The –BIPM model includes an integrated optical power meter. Not only can you identify live fibers and trace fibers, you can use this tool to check power levels as well. These units can also be customized for ONU detection.
The OFI-400 Series are 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 is designed and calibrated for use with 250µm, 900µm, ribbon, 2 mm and 3mm jacketed optical fibers.
The OFI-200 is a rugged, hand-held, and easy-to-use fiber optic test instrument designed to detect optical signals transmitted through a single-mode fiber without disrupting traffic on that fiber. It allows technical personnel to unambiguously identify a specific fiber and eliminates the risk of accidental disruption of revenue service.
