![]() This widely implemented Fiber Connector can be installed in about 45 seconds without consumables and offers best-in-class optical performance as a field-termination solution additionally, the high-precision ceramic ferrule multimode connectors guarantee a 0.1 dB typical/0.5 dB maximum insertion loss per connector pair for exceptional network productivity. Furthermore, our fiber optic cable connectors are manufactured of superior quality materials, delivering reliability that you can depend on.Īnother popular Optical Cable Connector that Fiber Savvy supplies is the Corning UniCam Fiber Connector. It is of particular importance to minimize these characteristics especially for long distance networking, as they can negatively impact functionality. However, there are two negative characteristics of fiber connectors to be considered: attenuation and reflection. This eliminates the air gap at the point of connection, resulting in minimal signal loss. Most Fiber Cable Connectors are spring loaded so that the fiber faces are pressed together when the connectors are mated. Our selection includes PC, UPC, and APC Fiber Optic Connector polish types. We also supply MIL-SPEC Fiber Cable Connectors for harsh, rugged environments including military applications. The most popular versions include, push-on Square Connectors (SC), snap-in Lucent Connectors (LC), and twist-on Straight Tip Connectors (ST). Whereas for those applications which high precision optical fiber signaling matters, APC should be the optimum alternative, but for less sensitive digital systems, UPC and APC can both perform equally well.Fiber Optic Cable Connectors are used to connect two runs of fiber optic cable. It is generally accepted that all of these connector options capture a place in the current market, and we cannot say anyone is better than the others since whether to choose UPC or APC in fact depend on your particular need. So, it actually depends on the real circumstances and various factors. However, when choosing the right connector for your specified application, factors like cost and simplicity should also be considered seriously, not just optical performance. The important point is that APC and UPC connectors cannot be mated, in case to cause poor performance or to destroy both connectors. Future higher-speed passive optical networks and other WDM applications that will use higher wavelengths via single mode fiber will also likely require the reduced return loss of APC connectors. With APC connectors being used by most cable companies, other FTTX providers in outside plant applications, and passive optical applications (both GPONs and passive optical LANs). UPC connector return loss should be -55dB or greater, while APC connector return loss should be -65dB or greater. This causes some differences in return loss, which is a measurement of reflected light that is expressed as a negative dB value ( the higher the value, the better). However, the angled end-face of the APC connector causes reflected light to reflect at an angle into the cladding versus straight back toward the source. With UPC connectors, any reflected light is reflected straight back towards the light source. UPC connectors are not exactly flat however, they have a slight curvature for better core alignment. So, it is essential for a connector with low back reflection and it could endure repeated coupling and decoupling without ORL degradation, which evolves the new type of connectors (APC).ĪPC connectors feature a fiber end-face that is polished at an 8-degree angle, while UPC connectors are polished with no angle. When the connectors are repeatedly coupled and decoupled, the ORL will starts to degrade. Usually the blue color UPC connector is used for single-mode fiber and beige color UPC connector is used for multimode fiber.Īlthough, UPC connectors have a low insertion loss, but ORL really depends on the surface finish of the fiber. UPC fiber connector can be used with both single-mode fiber as well as multimode fiber. UPC connectors do have a low insertion loss, but the back reflection will depend on the quality of the fiber surface and, following repeat mating/un-mating, it will begin to deteriorate. This UPC results in lower back reflection (ORL) than a standard PC connector, ORL values in (UPC) type of connectors is <-55dB, allowing more reliable signals in digital TV, telephony and data systems, where UPC today dominates the market. The UPC connector is built on the convex end-face attributes of the PC, but with an extended polishing method, which creates an even finer fiber surface finish known as Ultra Physical Contact.
