Handheld Optical Fiber Identifier

This handheld optical fiber identifier combines the capabilities of conventional fiber identifiers with advanced features for efficient network maintenance and testing. It allows non-destructive signal detection at any point on single-mode and multi-mode fibers, making it ideal for construction, troubleshooting, and maintenance tasks. The optical fiber identifier also integrates an optical power meter module and a red-light visual fault locator (VFL) for enhanced functionality.
