Hybrid Conversion Optical Fiber Coupler , LC To SC Fiber Adapter Low Insertion Loss

FA-AD-SP1LP-P , Plastic Hybrid Conversion Fiber Optic Adapter LC-SC Simplex For Singlemode Fiber

Insertion loss is a very important parameters for fiber optic adapter. But not all fiber adapter in the market has same performance so their insertion loss may be different.

To ensure two fiber cores contact and mating to be a line is the key point to ensure the excellent connection quality of the adapter, it mainly depends on the physical properties of the optical fiber, precision of the adapter pin and the assembly precision of the adapter . Meanwhile , the optical properties of the fiber and the polishing quality of the end face also have a direct affect on the optical performance and reliability of the adapter.

Insertion loss is the attenuation of the optical power caused by the adapter to the system (i.e., the relative reduction of the output power of the optical adapter with respect to the input power). The insertion loss is mainly caused by the deviation between the two optical fibers. If the two fibers are connected in a straight line, the deviation is zero, the insertion loss is minimized. But in the actual adapter mating, this is unlikely, because the fiber core and cladding of the fiber core and cladding with different pin holes are not concentric, concentricity of the outer diameter and pin hole are with error and it will cause the lateral deviation between fibers. The longitudinal gap and the end surface quality are also cause insertion loss. In recent years, the commonly use of UPC end face is better to solve the problem of vertical gap. In this way, the ferrule and the fiber end are with spherical polishing treatment, which makes the two pin meshing together under external force, and makes the contact point of the fiber deformation and become flat, forming full contact of the fibers and reduce the vertical clearance of optical fiber connector.

In the actual connection of optical fiber system, influence from the above factors may exist at the same time. In order to reduce the insertion loss, we should try to avoid the influence of the above factors.

Fiberall fiber optic adapter is with low insertion loss and small concentricity error, the changeability after 500times mating is 0.2dB only so it can avoid loss very well.
