How to make Cat5,Cat5e,Cat6 networking cable


First you need to prepare the following accessories:

Cat5 or Cat5e or Cat6

Bulk RJ45 Crimpable Connectors

RJ-45 Crimping tool


There are two kinds of Ethernet cables you can make. Straight Through and Crossover. STRAIGHT THROUGH - Ethernet cables are the standard cable used for almost all purposes. It is suggest you duplicate the color order as shown below. Note how the orange pair is not alongside as are all of those other twos. This setup allows for longer cord runs.

CROSSOVER CABLES -- The intention of a Crossover Ethernet cable  is to directly connect one computer to another computer (or device) without going through a router, switch or hub.

Action 1: Here's how to make a standard cable: cut into the plastic sheath 1 inch from the end of the cut cable.


Step two: Unwind and pair of the similar colors.

3: Crunch the wires regarding the fingertips and straighten them out as shown. (The cord colors make to form a straight through standard cat 5 cable as described above. )
Step four: Use scissors to create a straight cut across the wires 1/2 Inch from the cut sleeve to the end of the wires.
Step 5: Push the wires into the connector. Note the positioning of the blue plastic safeguarding. Also note how the wires go right to the end.


Step 6: CRIMPING THE CABLE... carefully place the connector into the Ethernet Crimper and piece of cake down on the handles securely. The water piping splicing tabs on the connector will pierce into all the eight wires. May locking bill that holds the blue plastic sleeve in place for a tight data compresion fit. When you remove the cable from the crimper, the cable is just about to use.

Step 7: Make sure to test the cables before installing them. An inexpensive Ethernet cable tester does this quite nicely.

The PLC Splitters work in PON


Most PON splitters are 1X32 or 2X32 or some smaller number of splits in a binary sequence (2, 4, 16, 32, etc. ). Couplers are basically symmetrical, say 32X32, but PON buildings doesn’t need but one fiber connection on the central office side, or maybe 2, so one is available for monitoring, testing and as a spare, so the other fibers  are cut off. Couplers work by busting the signal equally into all the fibers opposed to this of the coupler, splitters add considerable loss to a FTTH link, constraining the space of a FTTH link compared to typical point-to-point telco link. When designing a fiber optic network, here are guidelines on loss in PON couplers.

The splitter  can be housed in a central office or a pedestal in the neighborhood near the homes served. Some typical pedestal has connections to the central office, splitters and fibers out to each home in a sealed fencing. The main benefit of PONs is that this pedestal is passive -- it does not require any power as would a switch or node for fiber to the curb.

Below is the payout of a typical PON network with the equipment required at the central office, fiber distribution hub and the home. This drawing shows the venue of the hardware used in creating a complete PON network  and becomes the network vocabulary.
