Electrician & Construction Professional, CN CoterieWell, you can always use a connector to join two lengths of RJ45, but if you don't have a crimping tool, that's basically your only option. -
QuestionWhat are the picture representations of the color codes while in the RJ45?
Community AnswerThe colors are arranged in a similar fashion so that the computers know what they are sending/receiving. The lines don't specifically carry an arranged data line, but there are data+, data-, data2+ and data2+ in there. Wikipedia would help you with that. Fun fact: as long as the colors match at both ends you should be fine, if you messed up a color. However, the pairs ARE twisted still. There are two extra pairs in the cable which aren't used until cat6, with Gigabit. You can do perfectly fine without the extra pair for c5 and 5e. -
QuestionHow do I determine how many centimeters to cut when trying to crimp one?
Community AnswerYou can use the length of the RJ-45 connector itself. I use the width of my thumb. You will figure out a way that's good for you have you have done a few. Make sure the individual wire pairs maintain their twist right up to the crimp mechanism in the connector. If you have too much of the twisted wires showing prior to the crimp put both hands a foot down the cable and with one hand grip the cable loosely and gently slide the cable cover towards the crimp. The neoprene cover will stretch a little and make a nice looking crimp job. -
QuestionIs it really necessary to have one meter of cable for crimping the wires?
Community AnswerNot really, but usually, one meter of spacing fits perfectly.

QuestionWhat is the difference between CAT5e and CAT6e?
Community AnswerCAT6e cabling has higher performance specifications and is about 20% more expensive than CAT5e. -
QuestionCan I make my own color coding?
Community AnswerThe wires in a cat5 cable are arranged in twisted pairs to a specification that prevents crosstalk between pairs. If you use a different sequence, you will likely end up with a lot of data loss due to crosstalk.

QuestionWhat colors are used in LAN cables?
Community AnswerWhite and orange, white and green, white and blue, white and brown. Wires are twisted type we have to straighten the wires and connect with RJ-45 pin. -
QuestionWhat are the uses of the network cable?
Community AnswerEthernet cables are used to connect hard-wired network devices (computers, printers, game consoles, etc.) to a central point instead of using WiFi.
-
QuestionAre the ends of the Rj45 cable waterproof?
Community AnswerThey aren’t “waterproof” per se, but if subjected to accidental exposure to water, they should more than likely be perfectly fine to use after they are sufficiently dried. Never plug in or use a wet or damp Cat5 or Cat6 cable, as many devices run power through the cable (Power over Ethernet or PoE). This small amount of power is still enough to give you a shock, or fry your equipment.

QuestionHow much do I strip when crimping Rj45?
Community Answer1 inch of shielding, individual wires are not stripped, and extend 1/2 inch from shielding.
-
QuestionDo the two ends of the wires use the same specification of arrangement?
Community AnswerYes. The wires must be in the same order at both ends and not mirrored. The order specified by the Cat standards ensure minimal crosstalk between wires.
-
QuestionI don't have to strip those colored wires?
Community AnswerNo you don't, just follow the colour code guidance above. The colors are arranged in a similar fashion so that the computers know what they are sending/receiving.

QuestionOn the top side of the ethernet connector, should I see the cable ending or does it not matter as I used the crimping tool? The tip of the cables on the top side of RJ-45 is not in: is it a problem?
Bluecar5556Community AnswerThe wires ideally shouldn't be exposed outside of the connector. what the tutorial doesn't seem to mention is to ensure the cable jacket is past the strain relief in the connector. It's the rectangle portion where the wires come in. The crimp tool will also crimp the strain relief down, thereby retaining the cable at the jacket, preventing it from being pulled out by the strongest portion of the cable: the jacket.
