Facebook X LinkedIn Email
Fiber optic test equipment supplier AFL was awarded “Signal Identifying Apparatus for an Optical Fiber,” US Patent No. 7916983. The patent covers the company’s optical fiber identifier (OFI) technology for detecting the presence or absence of an optical network terminal on fiber-to-the-premises (FTTx) fibers. It is the first patent for the company’s Noyes Test and Inspection Div. The technology allows users to test passive optical network fibers at an external distribution cabinet without disconnecting fibers or disrupting services. It is commercially available in AFL’s OFI-FTTx fiber identifier. AFL is based in Spartanburg, S.C.

Glossary
optical fiber
Optical fiber is a thin, flexible, transparent strand or filament made of glass or plastic used for transmitting light signals over long distances with minimal loss of signal quality. It serves as a medium for conveying information in the form of light pulses, typically in the realm of telecommunications, networking, and data transmission. The core of an optical fiber is the central region through which light travels. It is surrounded by a cladding layer that has a lower refractive index than...
