it is unfair to say that one connector beats the others because it depends on of your particular needs, high application systems should use APC connectors but with fewer quality systems it is okay if you use UPC. It could be caused by absorption, bending or air gaps between components. Typical return loss in these connectors in single mode applications is -40. The difference between ferrule end faces results in different performances regarding the connectors losses, which are: Optical Return Loss : Also called back reflection, refers to the light that is reflected right back into the source that generated it, which. The curvature makes them look dome-shaped. This percentage of reflected light is expressed in a negative dB value (the higher the value, the better). Insertion Loss : It is the light loss that happens when a fiber component is inserted into another one to create a fiber optic link. PC, APC, and, uPC.

From Fiber Optic Precision Cleaning. And as the names suggest, all the polishing styles are different. UPC An extended polishing is given to these connectors end faces, which results in a better surface finish. PC, UPC and APC are acronyms for: P hysical, c ontact, u ltra, p hysical, c ontact. That convex shape locates the fibers at the highest point of the surface, which reduces air gaps between them. Their optical return loss is about -50 dB or higher. With the collaboration of Edward. Insertion loss can also be caused by a tiny particle of dust trapped between the connector end-faces. APC connectors handle multi-play systems which are why they are mostly employed in Radio Frequency (RF) applications, like catv or Distribution Antenna Systems. Choosing the right connector Choosing the right connector for a network depends on the network design and function. single mode or multimode fiber hamina

They are also used in optical passive applications, such as PON networks architectures or passive optical LANs. An important thing you have to keep in mind is tha t APC and UPC connectors cant be mated together because doing so will cause poor performance or may damage the connectors. PC, simplex, multimode connector, LC aPC, simplex, single mode connector or SC/. Insertion Loss Connectors Nominal Reflection Create your own infographics Typical insertion loss In PC, UPC and APC connectors should be less than.3dB. A ngled, p hysical, c ontact, they refer to the way the connector ferrule, the tiny ceramic structure that holds the fiber, is polished. In simple words, they are end-face configurations that are present in numerous connector types. They are also implemented in telephony and data systems. So a return loss of -40 dB means.01 of the light is reflected back, - 50 dB means.001 and -60 or higher means just.0001 of light is reflected back into the light source, which. APC Its ferrule is polished with an 8-degree angle that end-face brings the fibers tighter and reflects light at an angle into the cladding instead of reflecting it directly to the light sources, which causes its Optical. single mode or multimode fiber hamina
