I was looking for RJ45 data/data splitters but had trouble finding one designed for the correct purpose (having 1 at each end of a long network cable to connect two 10/100 Mpbs devices without running 2 long cables). I came across https://www.telephonewreckers.com.au/rj45-data-data-splitter but wasn't sure if it met this purpose so I called Telrex to explain the intended purpose and they confirmed that this item is intended for that purpose (the guy I spoke to was great). The item works perfectly and was priced very competitively. I'm really happy with my purchase!
