Fiber Optic Apc Connector

Fiber optic lc connector with apc upc polishing type.

Fiber optic apc connector.

Apc connectors are also commonly used in passive optical applications both gpons and passive optical lans due to the fact that many of these systems also use rf signals to deliver video. Better connectors lose very little light due to reflection or misalignment of the fibers. As you can see in the above you can learn that lc fiber connectors has apc and upc polishing types. Introduction to different connector types.

Because of the angle the reflected light does not stay in the fiber core but instead leaks out into the cladding. Each connector package includes a fiber connector cap and plastic boot. What are apc connectors. Whenever a connector is installed on the end of fiber loss is incurred.

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. 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. And it is hard to claim that one connector beats the others when your specification needs to consider cost and simplicity not just optical performance. These connectors also feature a low 0 25 db connector to connector typical loss.

However significant insertion loss can result when mating to different styles and because of this we recommend that fc apc connectors be mated only with other fc 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. Here the words upc and apc are related only to the fiber optic connectors and have nothing to do with fiber optic cables. To put it simply pc upc and apc refer to the polish styles of the ferrules inside the fiber optic connectors just as the following figure shows the ferrule is the housing for the exposed end of a fiber designed to be connected to another fiber or into a transmitter or receiver.

Apc fiber connector can only be used with single mode fiber and it is green. Like illustrated in the following picture. It is clear that all of the connector end face options mentioned above take a place in the market. 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.

Future higher speed passive optical networks and other wdm applications that will use higher wavelengths via singlemode fiber will also likely require the reduced return loss of apc connectors.
