What is Optical Fiber Testing Tools?

In order to meet the increasing demand for network, many network operators have begun to build faster and more stable optical fiber network. In order to build an optical fiber network, in addition to the use of high-quality st to lc fiber adapter, fiber optic cable attenuation, fiber access terminal box, after the completion of fiber installation, also need to use some testing tools. Some common fiber testing tools are described below. 

Red Light Pen

Red light pen is a kind of detection tool of optical fiber, which is mainly used to detect the connectivity of optical fiber and locate the fault point of optical fiber. Usually, in order to avoid the abnormal operation of the network after the optical fiber connection, the red light pen is used to detect the connectivity of each optical fiber patch cord before connecting the mode conditioning patch cord. If the red light is always on, it means that the optical fiber connectivity is good and can be used. In addition, when the network failure is caused by fiber breakage and bending, the red light pen can be used to detect the fiber optic patch panel, which can quickly and effectively find out the fault 8 port fiber patch panel, which can help people to timely replace the broken lc to lc multimode fiber patch cable and keep the network smooth.

Optical Fiber Microscope

Optical fiber microscope is a kind of fiber testing tool to detect the contamination of fiber connector end face. It can enlarge the image by 400 times. Nowadays, there are two kinds of common optical fiber microscope on the market, one is hand-held optical fiber microscope, the other is desktop optical fiber microscope. The hand-held optical fiber microscope can be used to detect the end face of the fiber connector of FC / SC / LC single mode fiber patch cord, and the desktop optical fiber microscope can be used to detect the end face of optical fiber connector of MTP / MTRJ / MPO / LC / SC multimode fiber patch cord.

Optical Fiber Power Meter

Optical fiber power meter is an optical fiber testing tool used to measure absolute optical power and relative loss of optical power of a certain section of optical fiber. In general, the optical fiber power meter is usually used with a stable light source. It can measure the loss of optical fiber patch cord, check its continuity and detect the transmission quality of optical fiber link. It can be used in optical fiber communication, optical fiber laboratory and other fields. Optical fiber power meter is more accurate than OTDR in optical loss measurement.

Laser Stabilized Light Source

Laser stabilized light source is a kind of optical fiber testing tool used with optical power meter to measure the relative loss of optical fiber power. In optical fiber communication, light source is needed to measure fiber loss, connection loss and optical receiving sensitivity, and laser stabilized light source is a light source that emits known power and wavelength to optical fiber system, so laser stabilized light source should be used when measuring fiber loss, connection loss and optical receiving sensitivity.
