how to operate optical fiber identifier

The Live Fiber Identifier allows you to detect traffic and measure signals anywhere onsinglemode fibers without having to disconnect them . It also lets you check for signal presence before rerouting or maintenance , perform continuity tests and verify cable labeling. Based on non-destructive macrobending technology,the fiber identifier doesn’t disrupt traffic,damage or overstress the fiber,enabling efficient,accurate and reliable data acquisition

BD-IF400D Optical Fiber Identifier is an important tool for optical maintenance, which is used for nondestructive
fiber identification project. Meanwhile it also has Visual Fault Locator module with fault location function.

Useing the macro bending technology on line for nondestructive testing, BD-IF400D Optical Fiber Identifier can measure the signal direction and power and avoid misoperation resulting in interrupted lines.

—Build in VFL function.The output power of BD-IF400D Optical Fiber Identifier is 10 mW.

—Low battery monitoring function, when battery power is insufficient to issue instructions to remind users to change batteries.
