Fiber optic connector grinding quality standards

Fiber optics have the ability to transmit efficiently, such as "television", "computers", "communication equipment" and so on can be increased by fiber optic signals. Because the principle of optical fiber is used to carry out long-distance information transmission. In fiber optic signal transmission in the quality of the connector assembly is very important, because in the data transmission will be on the connector end face grinding, why grinding? Because the connector end face grinding will improve the transmission performance, transmission efficiency faster, so the quality of the connector end face grinding is very critical, then how to determine the quality of the connector end face grinding? If the signal transmission anomaly, it will lead to data rate data bit error problem, because the quality of the echo reflection determines the fiber optic system speed and clarity and other system transmission problems. Commonly used connectors are generally denoted by PC, SPC, UPC, and APC, and the type of connector endface is generally described by these English acronyms, related to the design of the return reflection. Connector butt loss value. The general connector butt loss value is specified as <0.5db, but the general expectation has become <0.3db, because inaccurate fiber butt connection will cause the connection is not in place, as well as the connector end face grinding quality will affect the connector butt loss value. Whether the connector end face apex offset connector end face apex refers to the fiber core and connector after grinding the higher point of the measured distance between the connector, if offset will lead to the connector docking loss value and the quality of the echo reflection. In short, the transmission performance is good, fast efficiency of the fiber, its connector grinding quality must be very good.
