The fiber identifier is an essential tool for fiber optic maintenance, which is often needed during maintenance, installation, wiring and restoration without interrupting business. It is used for lossless fiber optic identification work, and can find and separate a specific fiber optic cable under the condition of detection at any position of single-mode and multi-mode optical fiber. By injecting a 1310 or 1550 optical signal with a specific modulation signal into the optical fiber at one end, it is identified on the line by the identifier, and can also indicate the business.

Shinho's new upgraded version of high-precision fiber identifier instrument is mainly upgraded on the display screen. The high-definition display screen can accurately display the direction of the identified light source, which is clearer and more intuitive. At the same time, it is more sensitive to the loss of optical fiber. The optical fiber direction and loss value identified by traditional fiber identifiers are often unclear. The upgraded fiber identifier solves this problem well, making the customers feel better.
