![]() ![]() The copper was stretched during the conductor straightening process. Note the exposed copper at the end of the conductors. Pass-through RJ45 8P8C plug in process of termination. Reduce termination mistakes (crossed conductors, etc.).The intent of this style of modular plug was to: These devices are relatively new to the scene. Pass-through RJ45 8P8C plugs have been around for about 15 years. This style of RJ45 8P8C plug takes time, experience, and patience to work with. ![]() However, not all installations are so simple and quite a few installers complained about the “guess, cut, fit, retry” method often associated with putting on 8P8C plugs. You plug one end into your PC and other end into your switch/router and off you go. For most people, buying a simple pre-terminated and factory made Ethernet patch cable worked great. Top this off with the desire to network computers together to share files more easily (and the invention of the Internet) and now everyone was looking to get in the Ethernet game. Manufacturers like Apple, HP, IBM, and more came up with affordable desktop computers. Ethernet wiring became more and more pervasive in the ensuing years. Solid nosed (otherwise called “standard”) 8P8C RJ45 Ethernet plugs have been around since 1995, designed for the original Cat5 Ethernet cable that ran at 100Mb/s (long since deprecated and replaced by Cat5e). Solid nosed standard RJ45 8P8C terminated In other words, buckle up because we are about to get deep in this and really flush out the truth. Finally, we will explain (all in one place) what the challenges are around terminating these annoying pieces of plastic onto Ethernet cable and define some best practices not only borne of my experience but also rather extensive BICSI and Fluke Networks training. We will parse through what the real issues are, and why they have shaped up this way to become such a persistent source of anxiety for newbies as well as experienced installers. The answer is far more complex than you might expect (isn’t it always?) and involves a discussion that goes far beyond just the pass-through style RJ45 8P8C connector plug. As it turns out, there is typically a kernel of truth in any urban legend or rumor. Typically, the question is followed by real life or anecdotal information about others who have had trouble with non-working or even damaged network devices. Written by Don Schultz, trueCABLE Technical Manager, Fluke Networks Copper/Fiber CCTT, BICSI INST1, INSTC, INSTF CertifiedĪ question that keeps coming up is “Do pass-through RJ45 connector plugs not work as well as the standard solid nosed kind?” We also get asked if pass-through RJ45 connectors pose any additional particular troubles with power over Ethernet (PoE). ![]() Terminating Pass-Through RJ45 Connectors onto Solid Copper Ethernet Cable - A Really Bad Idea? ![]()
