AFL Noyes OFI-200B Optical Fiber Identifier Live Traffic Fault Locator

AFL Noyes OFI-200B Optical Fiber Identifier Live Traffic Fault Locator is a fiber-identification device that detects signals on active fiber without interrupting service, enabling technicians to confirm whether a link is carrying traffic before performing maintenance or splicing work. It provides traffic direction recognition and signal presence verification, allowing users to determine the direction of live signals and to verify quickly whether a fiber path is active, which helps isolate faults and reduce service outages. The OFI-200B is part of AFL's Noyes Optical Fiber Identifier family, a line of field-tested instruments designed to identify live traffic on fiber networks and support non-destructive fault locating across telecom and data-center installations. As with other OFI models, this device is used in the field to minimize disruption during maintenance by confirming signal presence and direction without disconnecting fibers, a key capability for network technicians working on active links.
