Fc Pc Fiber Connector

Threaded fc pc connectors are designed for high vibration environments.
Fc pc fiber connector. The flat fiber connector is not suitable for single mode fiber cables with a 9µm core size thus it is essential to evolve into physical contact pc connectors. It is commonly used with both single mode optical fiber and polarization maintaining optical fiber. The tip is slightly curved to ensure only the fiber cores make connection during mating not the ferrules themselves. The pc stands for physical contact because these connectors allow the surfaces of two connected fibers to be in direct contact with each other.
Non angled versions may be denoted fc pc or with specialized designations such as fc upc or fcu to denote an ultra quality polish on the fiber end face. What is the difference. Thorlabs offers fc pc connectors with 2 0 mm narrow keys and ceramic ferrules. The parts are typically identified by adding apc angled physical contact to the name.
The pc is similar to the flat fiber connector but is polished with a slight spherical cone design to reduce the overall size of the end face. This helps to decrease the air gap issue faced by regular flat fiber connectors resulting in lower optical return loss orl with less light being sent back towards the power source. Pc fiber connector the physical contact is polished with a slight spherical design to reduce the overall size of the end face which helps to decrease the air gap issue faced by flat fiber connectors. So a return loss of 40 db means 0 01 of the light is reflected back 50 db means 0 001 and 60 or higher means just 0 0001 of light is reflected back into the light source which is why just apc connectors handle the demands of multi play services.
This is not much use for single mode fiber cables with a core size of just 8 9 µm hence the necessary evolution to physical contact pc connectors. Pc and upc are flat connectors with a straight polished fiber. For example an angled fc connector may be designated fc apc or merely fca. This difference is especially important when sending rf signal as opposed to digital data.
O fc pc ferrule connector physical contact most common of the fc connectors. Corning s fc adapters are available in a wide range of hybrid adapter styles to fit almost any. Fiber connectors are not all the same. Radiused zirconia ferrules to ensure low loss.
Our smaller bore connectors 30128c3 and 30140e1 accommodate our small core multimode fibers. Our larger bore connectors accommodate our large core fiber series and are ideal for optogenetics applications. Common types of fc connectors for example. Fc pc connector the fc connector is a fiber optic connector with a threaded body which was designed for use in high vibration environments.
The fc pc single mode connectors on this page feature a pre radiused 20 mm ceramic ferrule that minimizes back reflections. But it is since the decibel scale is not linear. Keyed 2 00mm 25 40 db return loss pm sm or mm fiber. As well as the different physical types such as sc fc and e2000 there is a big difference between apc and pc or upc connectors.
Fc connectors are used in datacom telecommunications measurement equipment and single mode lasers.
