There are several specifications of Ethernet RJ-45 connection over twisted pair: 10Mbit(Ethernet), 100Mbit (Fast Ethernet), 1Gbit (Gigabit ethernet) or 10Gbit ethernet.
Ethernet is officially standardized by IEEE standard 802.3. It was originally developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Nowdays ethernet over twisted pair (RJ-45 connection) runs at 10Mb, 100Mb, 1Gb or 10Gb per second. Ethernet uses a bus (very old coaxial cable) or star topology (standard UTP cable ewuipped with RJ-45 connectors).
Ethernet RJ45 connection and cable
Almost every ethernet network use Unshielded Twisted Pair (UTP) cable ended with RJ-45 connectors. Category 5 (CAT5), Category 5e or Category 6 (CAT6) cables are widely used, but other variations are available. EIA/TIA specifies RJ-45 connectors - properly called 8P8C - (ISO 8877) for UTP (unshielded twisted pair) cable. Crimping the RJ45 cable is easy.
Fast Ethernet
100BASE-TX (IEEE 802.3u) was introduced in 1995 and remained the fastest version of Ethernet before the introduction of Gigabit Ethernet. It runs on UTP data or optical fiber cable in a star wired bus topology, similar to 10BASE-T where all cables are attached to a hub. Fast Ethernet RJ-45 connected devices are generally backward compatible with existing 10BASE-T systems. The segment length for a 100BASE-T cable is limited to 100 metres. 100BASE-TX runs over two wire-pairs inside a Category 5 cable or above. Like 10BASE-T, the active pairs in a standard connection are terminated on pins 1, 2, 3 and 6.
Gigabit Ethernet
1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over copper wiring. The Gigabit RJ45 connection requires, at least Category 5 cable (the same as 100BASE-TX), but Category 5e cable (Category 5 enhanced) or Category 6 cable may also be used and is often recommended. 1000BASE-T requires all four pairs to be present and is far less tolerant of poorly installed wiring than 100BASE-TX.
10Gbit Ethernet
10GBASE-T (IEEE 802.3an-2006) is a standard released in 2006 to provide 10 Gbit/s connections over unshielded or shielded twisted pair cables, over distances up to 100 metres. Category 6a cable is required to reach the full distance and category 6 may reach a distance of 55 metres. The line encoding used by 10GBASE-T is the basis for the slower 2.5GBASE-T and 5GBASE-T standard, implementing a 2.5 or 5.0 Gbit/s connection over existing category 5e or 6 cabling. Cables which will not function reliably with 10GBASE-T may successfully operate with 2.5GBASE-T or 5GBASE-T if supported by both ends.

There are two standards for network RJ45 cable wiring: EIA/TIA 568A and EIA/TIA 568B. Both are correct. You may use either of them to crimp the Ethernet RJ45 network cable.

7 | BI+_D4 | Bi-directional+ | White with brown strip | BI+_D4 | 7 |
8 | BI-_D4 | Bi-directional- | Brown with white stripe or solid brown | BI-_D4 | 8 |
Note: It is very important that a single pair be used for pins 1 and 2; 3 and 6, 4 and 5, 7 and 8. If not, performance will be degraded.
How to wire your own RJ-45 Ethernet cable
The ethernet cable wiring is simple. You must have some RJ-45 connectors, UTP cable, Rj-45 Modular Connector Crimper and a hand. The ethernet cable,connectors and Connector Crimper are available at local computer store or most electrical centers.
Pull the cable off the reel to the desired length and cut.

Inside the ethernet cable, there are 8 color coded wires. They are twisted into 4 pairs of wires. One wire in the pair is a solid colored and the other is a primarily white with a colored stripe. Start on one end and strip the cable jacket off (about 2-3cm) using a stripper or a knife. The insulation of cable wires must remain intact!
Untwist the pairs and align the wires in the correct order (see the EIA/TIA 568B or EIA/TIA 568A pinout above ). Flatten the wires and trim the ends of the wires, leaving approximately 12-14 mm in wire length. Check the correct order, flattness and tightness of wires bundle.
Hold the RJ-45 connector (clip down) and carefully insert wires into the connector.
Each wire should be inserted as deep as possible (to the front of the RJ45 plug).
Check the wires order once again. Carefully hold the wire and firmly crimp the RJ-45 with the modular connector crimper.
Repeat the above for the second RJ45 connector of cable.
That's all. Test the Ethernet cable.
What if your Ethernet cable is failed to function?
Check the following:
Did you align wires in correct order on both ends of cable? Is pin 1 of connector wired with white-orange (EIA/TIA 568A) or white-green (EIA/TIA 568B) on both ends of cable?
If not, cut off connector and repeat above steps with NEW RJ45 connector.
Did you tightly press all metal pins of RJ45 connector?
Tightly crimp the connector with the crimper once again.
There are four most common Unshielded Twisted Pair Ethernet standards available nowdays:
Name | Speed | Standard | Wires used | Comments |
---|---|---|---|---|
10BASE-T | 10Mb/s | 802.3i | 2 pairs: pins 1,2,3,6 | Runs over four wires on a Category 3 or Category 5 cable. |
100BASE-TX | 100Mb/s | 802.3u | 2 pairs: pins 1,2,3,6 | CAT5 copper cabling with two twisted pairs. |
1000BASE-T | 1000Mb/s | 802.3ab | 4 pairs: pins 1,2,3,4,5,6,7,8 | At least Category 5 cable, with Category 5e strongly recommended copper cabling with four twisted pairs. Each pair is used in both directions simultaneously |
10GBASE-T | 10000Mb/s | 802.3an | 4 pairs: pins 1,2,3,4,5,6,7,8 | Uses category 6a cable. |
Ethernet UTP cable length:
Each network segment cable length may be up to 100 meters, although several chip manufacturers claim 150 meters. Autonegotiation is a requirement for using 1000BASE-T, according to the standard. Several device drivers will allow you to force 1000 Mbps full duplex to eliminate autonegotiation issues.
UTP network cabling
Category 5 cable, commonly known as Cat 5, is an unshielded twisted pair cable type designed for high signal integrity. With the 2001 introduction of the TIA/EIA-568-B standard for RJ-45 connection, the category 5 cabling specification was obsoleted and superseded by the category 5e specification.
The original 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 included four twisted pairs in a single cable jacket. It was most commonly used for 100Mbit/s networks, such as 100BASE-TX Ethernet, although IEEE 802.3ab defined standards for 1000BASE-T - gigabit Ethernet over category 5 cable. Cat 5 cable typically had three twists per inch of each twisted pair of 24 gauge copper wires within the cable. The twisting of the cable reduces electrical interference and crosstalk.
Cat 5e cable is an enhanced version of Cat 5 that adds specifications for far-end crosstalk, usually used for gigabit ethernet. Cat 5e cable does not enable longer cable distances for Ethernet networks: horizontal cables are still limited to a maximum of 90 m in length. Cat 5e cable performance characteristics and test methods are defined in TIA/EIA-568-B.2-2001.
Category 6 cable, commonly referred to as Cat 6, is a standardized twisted pair cable for Ethernetand other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for crosstalk and system noise. The cable standard also specifies performance of up to 250 MHz compared to 100 MHz for Cat 5 and Cat 5e. Whereas Category 6 cable has a reduced maximum length of 55 meters when used for 10GBASE-T, Category 6A cable is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same 100 meter maximum distance as previous Ethernet variants.

- I have been out-of-touch with Air Delights for some years. When I decided to return, they were there, ready and able to help me. They even had my old order records from years back. This was a great help to me. I didn't even need to order new dispensers , because my old ones worked just like new.
- Due to our order history they followed up with a phone call to ensure what was ordered was actually what we wanted. Turns out we ordered incorrectly. They made the adjustment on the phone and shipped the correct item.
- From seeing the pop-up ad, through ordering the needed parts cheaper than factory pricing, to installing for a flushable toilet again---THREE DAYS ONLY!!! Impressive, outstanding, and better than most!
- I've been using products from Air Delights for years and have loved all of the products that I purchased. There have never been any problems with the products or customer service. I've actually gotten some of my friends interested in the products.
- I've dealt with you folks before so I know the kind of service I will receive. I like the fact that there is a place like yours that people can shop at and get the service we deserve. I've decided we needed another set of this product in our upstairs bathroom since we have someone else utilizing the downstairs bathroom. GREAT SERVICE!
- They expedited shipping to me and got it her super fast and were MORE than courteous when I called. The Best!
- This commercial supplier has always been patient with my household sized orders. They even called once when what I had ordered was not the same as my previous orders. Saved me from having to return a mistaken order. I love their air freshener products. It's not always easy to find air fresheners that I can use with my allergies.
- Your company is the best.You save me money on the part that I needed.Also I will be order off your company if I need anything else.
- Our Flushmate 503 developed a broken cartridge at 4PM central time. AirDelights is pacific time, so by the time I placed my order it was 2:47 pacific time. They sent the parts by FEDEX next day standard delivery. I had the parts in my hand in St Louis MO at 10:18 AM the next morning. The order was before 3PM so they shipped the same day.
- Ease of ordering and length of time on delivery and the pleasing aroma of items purchased are all great! I will be purchasing more in the near future. Thanks to everyone involved with my order.

A RJ45 connector is a modular 8 position, 8 pin connector used for terminating Cat5e or Cat6 twisted pair cable. A pinout is a specific arrangement of wires that dictate how the connector is terminated. There are multiple pinouts for RJ45 connectors including straight through (T568A or T568B), crossover, rolled, T1, and loopback. Straight through is the most common type of cable and is used for connecting your computer to your network. The other pinouts are for specialty cables that are used for unique network applications. Straight-Through Pinout Within the family of straight-through color codes, there are two standards recognized by ANSI, TIA and EIA. The first is the T568A wiring standard and the second is T568B. T568B has surpassed 568A and is seen as the default wiring scheme for twisted pair structured cabling. If you are unsure of which to use, choose 568B.
T-568A RJ45 Pinout
T-568B RJ45 Pinout
Cross Over Pinout
A crossover cable utilizes two different RJ45 pinouts for the two ends of the cable. If you need to connect 568A equipment to 568B you can use a crossover cable.
