Panduit RJ45 keystone jack module blockout device

I recently got a phone call regarding a needed solution for being PCI compliant at the information outlet end. Being PCI compliant is a must for many retailers who do credit card transactions and can't have any open ports unaccounted for, even anyone accessing the wifi has to have their own wireless key accounted for.

After doing some research it appears that the easiest way to lock out the RJ45 information outlet is by using a blockout device by Panduit. It's an easy, simple and secure way to control access at the outlet, especially in those very heavy public areas. Let's check it out from our YouTube channel.



There it is, easy right! I still get a good chuckle hearing about those kids and their crayons.

How to wire a 66 block without a punchdown tool

If your looking into wiring a 66 block and you've never wired one before or maybe you have many moves and changes and your tired of re-punching the block, this might be an excellent option for you.

Looks really cool so I brought in a sample to check out.

We're considering stocking these so we asked our Facebook fans what they thought and here's what they said.

So it sounds like these blocks are designed with high speed transmissions in mind. So far the jury is still in session. Please, if you have any questions comment below and let us know if we should stock these. 

Thanks!

RGBHV cable with BNC connectors and RCA connectors

If your in the professional broadcasting industry RGBHV cables are a must have for many different kinds of high definition applications. If your broadcasting coaxial cabling infrastructure consist of high quality HD-SDI coax cables such as Belden 1694A or 1855A your probably going to make sure your RGBHV cable is also on the same level as the rest of your infrastructure.




These assemblies are available in many different lengths, assembled in America using an American made coaxial cable, (The parent company of Tappen is Southwire, they make kick-ass wire). If image quality is a top priority why cut corners.

Corning CamSplice mechanical splice tool overview and How To

I just want to talk about this tool by Corning as an easy and effective way to mechanically splice fiber optic cable.



Let's check out some of the features.

* No adhesive or epoxy required
* Reduces splice time with no curing needed
* Universal one part fits all fiber coatings
* No polishing required
* Reduces installation time
* Fiber alignment mechanism
* Self centers the fiber for low loss

Now let's figure out how to splice fiber optic cable.



It's a very simple process and I know you can do it. Just a quick tip, if your repairing a direct burial fiber it's recommended that you replace the cable at least 30 feet in each direction so you'll have to do as least 2 splices per strand of fiber.

Introduction to your MTP fiber optic cable polarity wiring

If your getting into MTP cables you need to know what type of polarity you need to configure these cables to, a good place to start is with the TIA-568-C.O standard. This standard provides guidance on serial transmission fiber polarity for fiber networks installing MTP optical connectivity. Each 12 strand MTP connector is divided into six 2 strand fiber optic serial circuits that require polarity management that can be achieved using one of a few methods.

I'm going to start you out with what so far seems to be the most popular polarity pinout, this would be the "Universal Polarity Management Method" and is used in many Corning fiber networks. It seems to be a little odd that this would be the most popular so far because the universal method is not included in the TIA standard but it does meets the "intent of the standard" that's according to Corning. Makes good sense that this would be most popular because Corning seems to be the biggest giant in the fiber optic cable market.

This system is mated key-up to key-down. This method supports simple concatenation of multiple trunks without effecting polarity. Accommodates all simplex/duplex connector types. The components related to your MTP connector will also allow for easy moves without polarity concerns used in other methods.

The next most common polarity pinout method I see is "Method B". This uses a single module type wired in a straight-through configuration and standard patch cords on each end. One thing that will stand out to you is how all the components in the system are key-up to key-up. This method will require more planning for your modules location. This method also does not accommodate angle polished single mode connectors. It's also a common method in Commscope fiber optic network infrastructures.

Now thinking about it, the next method is not far behind after looking at my sales history of MTP cables. Let's talk about "Method A". This uses a single type wired in a "Straight-Through" configuration and two different patch cords in a optical circuit. One cord is straight and the other is flipped. All components in the channel are mated key-up to key-down. Because the polarity is addressed in the patch cords the end user is responsible for managing the network.

The last method I'm going to brush on is "Method C". This uses a pair wise fiber flip in the trunk cable to correct for polarity. This will enable the use of the same module on both ends of the channel and standard patch cables. Because the polarity is managed in the trunk, extending links requires more planning to maintain polarity. The TIA standard does not mention text regarding the ability to migrate to parallel optics, but parallel optics capability can easily be achieved with a special patch cord to reverse the pair-wise fiber flips in the trunk.

Now that you have a better under standing of what polarity you might need I'll be waiting for your phone call when your ready to order these! 888-797-3697 ex. 232
