The largest loss comes from the connector. The last thing you want to do is cause permanent transmitter damage-especially with higher-cost singlemode equipment.Īnother important point: Cable loss is typically the smallest contributor to system attenuation. Not only does mating cause poor performance because the fiber cores will not touch, but it can also destroy both connectors. One thing that should be noted is that APC and UPC connectors cannot and should not be mated. 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. That is why we see APC connectors being used by most cable companies and other FTTX providers in outside plant applications.ĪPC 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. For example, in higher optical wavelength ranges (above 1500 nanometers) like those used for RF video signals, reflected light can adversely impact the signal. Some applications are more sensitive to return loss than others they call for APC connectors. Our FiberExpress Fusion Splice-On Connectors exceed standards when it comes to insertion loss.įiber Express Fusion Splice-On Connectors: Insertion Loss Fiber Typeįiber Express Brilliance Universal Connectors Fiber Type In fact, insertion loss on Belden’s FiberExpress connectors is the same for UPC and ACP singlemode connectors. Achieving low insertion loss is typically easier with UPC connectors due to less air gaps than APC connectors however, manufacturing techniques have improved significantly to create more precise angles on APC connectors and bring insertion loss closer to that of UPC connectors. Insertion loss is what we use to determine loss budgets. Remember, return loss is different than insertion loss, which refers to the amount of optical power lost through a connector or cable length. Industry standards recommend that UPC connector return loss should be -50 dB or greater, while APC connector return loss should be -60 dB 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). The angled endface of the APC connector causes reflected light to reflect at an angle into the cladding vs. What does this difference mean in terms of performance? With UPC connectors, any reflected light is reflected straight back toward the light source. UPC connectors are blue while APC connectors are green. Another more obvious difference is color. UPC connectors are not exactly flat, however they have a slight curvature for better core alignment. APC connectors feature a fiber endface that is polished at an eight-degree angle UPC connectors are polished with no angle. The main difference between APC and UPC connectors is the fiber endface. Ever wonder what the difference is between ultra physical contact (UPC) and angled physical contact (APC) singlemode fiber connectors and which one to use? As usual, the answer is, “It depends.”
