CAN A CAT6 CONNECTOR WORK ON A CAT5E CABLE?

If you’ve been running Ethernet cable or making patch cables for any length of time, you now have an assortment of RJ45 connectors and cable types representing the evolution of your network. You may be tempted to use what you have on hand to do your work, mixing and matching a bit. Visions haunt you of hunting through the cable jungle only to find that it was one of your cables that came loose, cable from connector, or even worse — looks just fine, but really isn’t making reliable contact. But is that just unnecessary worry?

It Just Might (Reliably) Work!

If you’re using Cat5e cable and all you have is newer Cat6 connectors, you may be all right. Generally, connectors may be backwards compatible with cable from older standards, but the reverse is not true — if you’re pulling Cat6 cable, time to update your Cat5e and older connector collection! There are some things to consider in proving that you’re using a workable combination of cable and connector, including a simple friction pull-test, cable and connector measurements, conductor fit and contact quality. There’s also the question of whether you’re already playing the odds with your cable quality.

Does It Hold Securely?

This is a simple test that determines whether the diameter of the cable is in the range which works with the Cat6 connector. This test ensures that the primary latch takes the strain of cable pull, rather than the conductors. Some Cat5e cables won’t be big enough for the latch to grab.

  1. Cut a 4 inch piece of cable
  2. Insert it into the connector
  3. Crimp the connector
  4. Tug and test the strain relief from the crimped cable

Do the Numbers Match?

Cat6 connectors are designed to accommodate much larger cable diameters than Cat5e, so most cables should fit — but check the numbers. For example, Cat6 EZ-RJ45 connectors from Platinum Tools use 0.275 inches as a maximum cable OD, which is plenty for a typical 0.205 diameter Cat5e cable. For these EZ-RJ45 connectors, individual insulated conductors must also be 0.041 inches or less to fit through the connector. Cat6 connectors are designed for 24 and 23 AWG conductor wire sizes, and less can be problematic. Most 24 AWG Cat5e cable should measure up, but depending on the source it sometimes it doesn’t, as mentioned below.

Will the Connections Work?

Conductor size determines whether the connection is going to be reliable or not. Although Cat6 solid conductor cables usually contain 23 AWG wire, Cat5e cables with 24 AWG conductors should seat and connect properly in the Cat6 connector. Conductors on the small side which worked for Cat5e may float or shift in the connector channels. This can cause problems ranging from an obvious open circuit to failure during certification. Ongoing issues from unreliable and incomplete surface contact may also occur.

Where Did You Get That Cable?

The volume of cable that installations use can tempt the use of questionable cable, often unknowingly. Purchasing can find a great price that appears to meet specs, but fails in the field. Cable such as “offshore deals” (some have other, more colorful names for it) can have marginal performance and quality. Marginal wire sizes, in particular, can produce intermittent or failed conductivity in Cat6 connectors, and PoE heat problems.

Once you do your homework, using those spools of Cat5e cable with new Cat6 connectors is a pretty safe way to keep moving forward with your network installations. Remember to check that the strain relief is from crimping the cable jacket, protecting the conductors, and that your conductors are seating securely in their channels for reliable connections at any speed, and in any rated conditions!

How To Identify, Verify, and Test an RJ45 Pinout

Ethernet cables, the 8-pin variety which are terminated by an RJ45-style connector, can come in just enough varieties to spread confusion. There are four basic types:

  • Rollover type which only looks like an Ethernet cable, but can be useful with Cisco equipment consoles. Usually light blue, sometimes with a 9-pin RS-232 connector on one end.
  • Straight through type, connecting to networking equipment such as routers, hubs, and switches, which is the predominant cable type now.
  • Crossover type which was necessary to connect computer to computer without any intervening network equipment. Becoming unnecessary.
  • A fourth type, which has to be mentioned — home made cables with nonstandard pinouts, often non-Ethernet. Hopefully, someone labeled them and identified their use.

Sorting Spares

The first place where you’ll have to figure out which cable is which is when you’re retrieving spare premade cables from your extras box. You should only save known good cables, but you can use a basic cable tester with remote to check out continuity and wiring. The Platinum Tools Lanseeker does an excellent job at this.

Common Cable Arrangements — TIA-568A/B

Look at the RJ45 connector on a cable, holding the flat underside toward you. On the left is pin 1. For Ethernet use, the straight through configuration is what you’re likely to see, in TIA-568B arrangement:

  1. Orange stripe
  2. Orange
  3. Green stripe
  4. Blue
  5. Blue stripe
  6. Green
  7. Brown stripe
  8. Brown

For the less common TIA-568A arrangement, pins one and two are Green stripe and Green, and 3 and 6 are Orange stripe and Orange. The connections are the same, but the colors are swapped. You can identify them that way, and suspect which one you have just by the pin 1 color.

Standard, Crossover, and Rollover

Computer equipment sends data using pins 1 and 2, and receives using 3 and 6. This is part of a convention which is used when these connectors and cables are used for Ethernet. For shorthand, you can call this MDI, or the Medium-Dependent Interface.

In the past, computer-to-computer “crossover” cables were needed when bypassing network equipment. As a variation, they were called MDI-X, for Medium-Dependent Interface Crossover. Network interfaces have advanced enough to detect cabling and switch pin usage as needed, so crossover cables are rarely used.

Crossovers not only exchange pins 1 and 3, 2 and 6 to exchange data and transmit, but also 4 and 5 cross and connect to 7 and 8, exchanging blue and brown pairs. Testers such as the Platinum Tools VDV MapMaster 3.0 can check all of the exchanges in a crossover cable quickly and simply, and identify common wiring problems in the cable such as miswires and split pairs. Of course, it can’t detect wrong wire colors!

For completeness, the rollover cable reverses every pin: 1 to 8, 2 to 7, etc., as if the wires were part of a ribbon cable which was reversed. If you have Cisco networking equipment nearby, you may have a few console cables in your cable box which are wired this way — beware!

Verification and Testing

Testing devices such as the Platinum Tools VDV MapMaster 3.0 can verify cable wiring, check for shorts and opens, and verify more exotic cable configurations such as mixed data and video. They can also map cabling using the remote module.
