Apc Fiber Connector

With an apc connector the angle directs the light off into the side walls of the fiber where it is absorbed by the fiber jacket.

Apc fiber connector.

Considered by some to be the modern replacement of the sc connector. The fc connector is a fiber optic connector with a threaded body which was designed for use in high vibration environments. Differences between upc and apc connector. An optical fiber connector terminates the end of an optical fiber and enables quicker connection and disconnection than splicing the connectors mechanically couple and align the cores of fibers so light can pass.

See the below images for better understanding. With upc connectors any reflected light is reflected straight back towards the light source. The uses of apc connectors. The difference is that single mode lc connectors have it in apc upc polishing type while multimode lc fiber connectors have upc polishing only.

So why then is the apc connector so important in fiber optics. Another more obvious difference is color. Its introduction was less successful in part due to initially high license fees. Like illustrated in the following picture.

It is commonly used with both single mode optical fiber and polarization maintaining optical fiber fc connectors are used in datacom telecommunications measurement equipment and single mode lasers they are becoming less common displaced by sc and lc connectors. In digital applications there is no issue using pc and apc connectors as light can get though in an on off manner. Upc connectors are not exactly flat however. Apc connectors feature a fiber endface that is polished at an eight degree angle.

They have a slight curvature for better core alignment. The best feedback examples from my previous blog came from people experienced with fttx and radio frequency rf applications. Because of the angle the reflected light does not stay in the fiber core but instead leaks out into the cladding. The main difference between upc and apc connector is the fiber end face.

Apc connector is a type of fiber connector that minimizes backreflection due to a 5 to 15 angle polish applied to end faces. The advance in analogue fiber optic technology has driven demand for it to replace more traditional coaxial cable copper. Upc connectors are polished with no angle. The main difference between apc and upc connectors is the fiber endface.

These connectors also feature a low 0 25 db connector to connector typical loss. What are apc connectors. Sc apc connector is commonly used in applications that are much more sensitive to return loss and requires for high precision signal such as fttx fiber to the x video delivery through rf signal wdm wavelength division multiplexing applications and analogue equipment like cctv. Better connectors lose very little light due to reflection or misalignment of the fibers.

Each connector package includes a fiber connector cap and plastic boot.
