Excess loss is the ratio of the optical power launched at the input port of the splitter to the total optical power measured from all output ports. Signal loss within a system is expressed using the decibel (dB), which is a measure of signal power attenuation.ġ. Here is a table of typical losses for splitters. Insertion loss testing of the optical splitter is very important to ensure compliance to the optical parameters of the manufactured splitter in accordance with the GR-1209 CORE specification. The following picture shows an optical splitter used in a PON system. Optical splitters play an important role in FTTH (Fiber to the Home) networks by allowing a single PON network interface to be shared among many customers. When the splitter has two inputs and four outputs, it is called a 2x4 splitter. Likewise, there are 1x4 splitter, 1x8 splitter, 1x16 splitter, 1x32 splitter, and so on. For example, a splitter with a 1x2 certain ratio configuration means that it has one input and two outputs. Optical splitters, including FBT (Fused Biconical Taper) couplers and PLC (Planar Lightwave Circuit) splitters, are common passive optical devices that split the fiber optic light into several parts by a certain ratio. In this tutorial, we are going to introduce optical splitter loss testing with optical power meter and light source. There is something different between testing an optical splitter and a patch cable although both of them use an optical power meter and light source to test. If you ask on reddit about DIY PC difficulties, you get meme LEGO postings, instead of usefull informations.Optical splitters are usually used in passive optical networks (PONs) to distribute fiber to individual homes or businesses. Not sure if your idea is that great, since modular PSUs are fine if you know basics about DIY PC building.īut I dont blame anyone that doesnt know basic stuff like this. Mixing cheap cables with high end PSUs for optical reasons or using thin cables because they are easier for cable management could easily create issues for the manufacturers with RMA for OCP/ripples/or even hot cables, with 100% user fault. While I do think it would be great to have standardized pin layouts, it would require every different manufacturer to change their maybe better layout and tooling for no reason. ![]() Then you got the whole quality difference in cables and the used AWG - again a cost/budget decision and the efficiency and quality of the power delivery changes with different cables. Some PSUs use them, some are meant to be cheap and not have them. Some cables have capacitors and such to reduce ripple. Considering we still don't have a standard for front panel connectors (for what reason, I couldn't tell you since they are the most annoying connectors in a PC), I don't see this happening any time soon.Ĭommon sense and reading (if you are new to PCs) will prevent stupid mistakes like this. ![]() The only thing that could every solve the problem is if a standard was created for the PSU that all manufactures agreed to use. ![]() Why would every company communicate to make sure they all had different connectors when they all already put big warnings in the manual about it? Would be nice if psu manufacturers had different arrangements of those 6 pin connectors so a cable from one company wont physically fit in a psu from a different company.Ī lot of them are keyed differently, but some might end up the same because competing PSU manufacturers aren't going to waste time communicating about this when it's the customer's fault for not reading the manual.
