Thorlabs offers fc pc connectors with 2 0 mm narrow keys and ceramic ferrules.
Fc pc fiber connector.
Pc and upc are flat connectors with a straight polished fiber.
Threaded fc pc connectors are designed for high vibration environments.
Our fc pc connector features a patented nod spacer element for greater reliability and ease of assembly.
Our larger bore connectors accommodate our large core fiber series and are ideal for optogenetics applications.
The parts are typically identified by adding apc angled physical contact to the name.
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.
Our smaller bore connectors 30128c3 and 30140e1 accommodate our small core multimode fibers.
O fc pc ferrule connector physical contact most common of the fc connectors.
It is commonly used with both single mode optical fiber and polarization maintaining optical fiber.
Fiber connectors are not all the same.
The tip is slightly curved to ensure only the fiber cores make connection during mating not the ferrules themselves.
What is the difference.
Radiused zirconia ferrules to ensure low loss.
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.
The fc pc single mode connectors on this page feature a pre radiused 20 mm ceramic ferrule that minimizes back reflections.
Fc connectors are used in datacom telecommunications measurement equipment and single mode lasers.
The pc stands for physical contact because these connectors allow the surfaces of two connected fibers to be in direct contact with each other.
But it is since the decibel scale is not linear.
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.
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.
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.
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.
We also provide an fc fiber coupling adapter family to support fc pc interconnection.
Keyed 2 00mm 25 40 db return loss pm sm or mm fiber.
Corning s fc adapters are available in a wide range of hybrid adapter styles to fit almost any.
For example an angled fc connector may be designated fc apc or merely fca.
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.
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.
