We’ve covered fiber insertion loss testing in depth in many blogs, so by now you should know that it is the loss of signal that happens in a channel due to the length of the cable and any connectors, splices or splitters. But there is one aspect of insertion loss that has appeared to cause some confusion—the fact that TIA standards specify a maximum fiber connector loss of 0.75dB. If the design calls for multiple connection points and this value seems too high for your channel, it’s probably because it is.
