>> Optical Loss Media
- To measure the total loss across the fiber, including weld and connector loss. It is also used to identify faults, such as breakages and measure the optical reflectance attenuation.

Optical Loss Measurement Methods
Currently, the loss of optical fiber welds is usually determined through two main methods: measuring the loss with an Optical Power Meter and an OTDR Optical Reflectometer
>> By Optical Power Meter
 * Measurement purposes: Power meter uses insertion loss measurement method. This method will help users know the exact loss of fiber optic cable.
 * The necessary equipment: optical power meter, optical light source (you can use converter, SFP optical module, etc.), 2 adaptors (connector), 2-wires connection (connecting wire must have core diameter and sheath corresponding to the fiber to be measured).
>> By OTDR Optical Reflectometer
 * Measurement purposes : OTDR optical Reflectometer applies the method of measuring the return loss loss. This is a method that allows the user to evaluate the return loss by measuring the reflected power of the optical fiber.  
 * The necessary equipment: OTDR optical reflex meter capable of measuring the entire length of fiber with several sets of wires, fiber coupler, fiber cutter, liquid to match fiber extracts, buffered fiber coils, fiber optic pliers, etc.
