Discount cat5e: Connectors
The most common and regularly used Ethernet connector is RJ45 also known as the 8P8C- 8 position 8 contact plugs.
Most of the time rj45 connectors are used to terminate twisted pairs with a T568A and T568B pin-out. Now T568B is the standard pin-out if its the same on both sides of the wire. If one side Is t568A and the the other is T568B, then this is called cross over. Cross over cables are rarely used today, but before auto Medium Dependent Interface/ Medium Dependent Interface Crossover became popular, crossover cables are required to connect devices such as computer to computer via Ethernet cable. The feature of Autocross which automatically correct errors in cable selection, making the distinction between Straight through and Crossover unimportant.
Rj45 connectors are commonly used in Computer networking, and almost all today's network communication are carried over by cat5e (Category 5 Enhanced) and Cat6 (Category 6) cables with rj45 connector crimped and terminated on both side.
Even though cat6 offers superior connection and networking speed than cat5e, it is still not as popular as cat5e. one of the reason being, cat6 cables are not flexible, which means if bended or incorrectly installed, it's performance will be greatly discounted. The distinction between cat5e and cat6 will be discussed in another day.
Lastly, there are two types of Rj45 plugs, Western Electric/Stewart Stamping (WE/SS) and Tyco/AMP. It is hard to tell and distinct these two types of connectors, because they look similar. However, Tyco/AMP type connector cannot be interchangeable with WE/SS. Reason being their sizes are different, Tyco connectors have smaller spaces between contacts, so if you use a WE/SS crimper, it will damage or maybe even crush the connector. The most popular type of connector today is WE/SS, but still becareful when choosing connect and hand crimper or crimping machines to avoid possible conflicts.
There are so many RJ45 Connector maufactures here within USA and oversea such as China. Prices varies from 10 cents each to perhaps 50 cents each depends on the brand and manufacturer, and many of them offer huge discount when you buying bulk, some give discount on pricing while others may offer free shipping, so shop around before you purchase.
Discount cat5e: material costs
While ebay or some other online seller sell their 50 feet cat5e for 12 dollar each, how much does it cost to make a 50 feet cat5e in reality?
Let us check the material cost:
Cat5e bulk cable 1000 feet price varies from - 70-100 bucks shipping included, typically its about 70 dollars per 1000 feet with shipping. Of course oversea companies do sell them for less, but they do not sell in small quantities.
RJ45 connectors: if you google them or search on ebay, you will find the cost roghly 3 dollars to 4 dollars for 10 pack, im talking about the 50 micron gold rj45 male connectors.
Now crimping tools can be find on some manufactures websites, or simply once again google, it costs about 30 dollars to 40 dollars.
calculation 7cents per feet x 50 feet = 3 dollars and 50 cents, assuming 30 cents per rj45 connector its 60 cents, 3.50+.60 = 4.10 cents, and that is your material cost to make a 50 feet cable.
lastly, shipping, one of the most headaching thing you have to think about, if you plan to sell your cable. US priority mail charges 4 dollar and 75 cents per lb, and ups charges 5 dollars for ground shipping, now if people are not going to buy a 5 dollar cable with a 5 dollar shipping.
Discount cat5e: wikipedia
Now there are a lot information available on Wikipedia.com
this link has alot information regarding cat5e, and their ping out standards: http://en.wikipedia.org/wiki/Category_5_cable#Individual_twist_lengths
here are some stuff from that page, i did not write any of these:
Category 5 The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. These documents specified performance characteristics and test requirements for frequencies of up to 100 MHz. Category 5 cable includes four twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs (this latter form of interference is called crosstalk). It is most commonly used for 100 Mbit/s networks, such as 100BASE-TX Ethernet, although IEEE 802.3ab defines standards for 1000BASE-T - Gigabit Ethernet over category 5 cable. Cat 5 cable typically has three twists per inch of each twisted pair of 24 gauge copper wires within the cables.
Category 5e Cat 5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. It was formally defined in 2001 as the TIA/EIA-568-B standard, which no longer recognizes the original Cat 5 specification. Although 1000BASE-T was designed for use with Cat 5 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BASE-T. Despite the stricter performance specifications, Cat 5e cable does not enable longer cable distances for Ethernet networks: cables are still limited to a maximum of 100 m (328 ft) in length (normal practice is to limit fixed ("horizontal") cables to 90 m to allow for up to 5 m of patch cable at each end, this comes to a total of the previous mentioned 100m maximum). Cat 5e cable performance characteristics and test methods are defined in TIA/EIA-568-B.2-2001.
Connectors and other information The cable exists in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking and is suited for reliable connections with insulation piercing connectors, but makes unreliable connections in insulation-displacement connectors. The solid form is less expensive and makes reliable connections into insulation displacement connectors, but makes unreliable connections in insulation piercing connectors. Taking these things into account, building wiring (for example, the wiring inside the wall that connects a wall socket to a central patch panel) is solid core, while patch cables (for example, the movable cable that plugs into the wall socket on one end and a computer on the other) are stranded. Outer insulation is typically PVC or LSOH. Cable types, connector types and cabling topologies are defined by TIA/EIA-568-B. Nearly always, 8P8C modular connectors, often incorrectly referred to as "RJ-45", are used for connecting category 5 cable. The specific category of cable in use can be identified by the printing on the side of the cable.[1] The cable is terminated in either the T568A scheme or the T568B scheme. It doesn't make any difference which is used as they are both straight through (pin 1 to 1, pin 2 to 2, etc); however mixed cable types should not be connected in series as the impedance per pair differs slightly and could cause signal degradation. The article Ethernet over twisted pair describes how the cable is used for Ethernet, including special "cross over" cables.
Bending radius Most Cat.5 cables can be bent at a radius approximately 4 times the diameter of the cable
Discount cat5e: how to make
Now if you are someone who wants to make alittle cash on the side by making and selling cat5e cables go ahead. I'll provide the information on how to make them. Now materials you need: Bulk Cat5e cables, some sort of measure device, Scissor, and a sharp razor blade, two rj45 connectors, boots are optional, and crimping tool.
First decide how long you want your cables to be, measure it then roll it with either hand or a reel. Cut the cable end that is still connected to the bulk. Now stick the two ends of cables out and carefully use the razor blade to cut off the skin, make sure you dont damage the 4 pairs of twisted wires inside, remember if it is your first time, cut off more skin, 1 inch or so.
now follow the pingout and sort the cable with either ur hand or tools. Bring all the wires together and trim them to even length. now insert the wire into the rj45 connector, make sure your wires reach the end of the connector, then lastly use the crimping tool to crimp and wallaah, you have just made your first cat5e.
If you need more information feel free to google, there are many tutorials out there, and remember the cheapest way to get discount cat5e in bulk is ordering in large quantities

Discount cat5e
Now before we begin the discussion of Discount cat5e, i think we should know what cat5e is first. Cat5 cable also known as cat5 is a four pairs of twisted cable type designed for high signal integrity. There are shields, and none shielded cat5s, but most Ethernet cat5 are none shielded. Shielded means there is a metal wrapping around the connector for superior connection, but of course the price is much much greater. As technology advances generally cat5 has been replaced by enhanced cat5s, or cat5e.
normal cat5e usually uses RJ45 connector, with 50 micron gold for better connection. Cat5e has 4 pairs of twisted cables inside, colors are : brown, white brown, green, white green, blue, white blue, orange, and white orange. now 568b has become the standard pinout for cat5es but there is also 568a, known as crossovers.
Now lets get into the topic of discount cat5es, yes there are many cat5es out there for low prices. however, the question is, are they really worth the money? Now, no business man with the right mind would sell an item below its cost. which means the so called discount cat5es materials are cheap to begin with. now ask yourself one question, would something cost 1 cent has the same quality as something that costs a dollar?? Most of the time, the answer is no.
And cat5es are no exception, Many cheap cat5es are None-OEM- ORIGINAL EQUIPMENT MANUFACTURE. Which means they could've manufactured the cables themselves with low cost. Whether if you are an office, or just some one who needs an ethernet cable, Something that breaks easily is not the item you want. With OEM cat5e manufactures, u get the technical support and if it breaks they fix it. Usually they only cost a dollar or two more than the NONE-OEM manufactures.
Now before you buy Discount cat5e Cables, ask yourself could the few dollars you save now come back and cost you more?
