There has been a lot of talk about convergence in the cabling world; some of this has been driven by new technology and market overlapping. Today’s integrator has the ability to install a system that covers phones, computers, security, audio/video and even low-voltage power.

I'm a huge fan of a British TV series from the 1960's called "The Prisoner". It starred Patrick McGoohan (reprising his 'Secret Agent' role) who is captured and sent to this strange land where they try and break him. It was only 13 episodes long and was seen as a summer replacement series in the USA.

The location footage for that show was filmed at a resort on the northern Welsh coast called "Portmeirion". I have visited there many times. Once I went by train from London to Portmeirion, which was one of the strangest trips I have ever taken. The train stops in the middle of Wales at a train station literally in the middle of nowhere. I was told it is the only train station NOT accessible by car in the entire British Isles. The reason for it is that the Welsh railroad uses a different rail gage, so the British trains cannot go there. You get off one train and on to another, just because the gage changes.

We're very proud of our professional audio and video cables. Our professional cables are so superior that most broadcasters simply won't use anything else. But when it comes to commercial designers and installers, sometimes they don't need all the bells and whistles we put in and they're willing to take less quality (for a lower price, of course).

Where we test every foot of cable we make such as our precision broadcast coaxes, most manufacturers "batch test" meaning they test one reel out of a batch of 25. By the way, when we say we test every foot this means we have test gear in the factory where the cable is made. Want a tour of a Belden factory? We would be happy to arrange a tour. No kidding, just send me an email.

Back in the old days of analog audio, splitting a signal was no big deal. Just use a 'Y' adaptor. Or if you're punching down wires, just punch another pair on top of the first. Of course, each signal will be 3 dB lower than the original, but that's not a worry. That's because the wavelength of audio is miles long (quarter-wavelength at 20 kHz is more than 2 miles!).

While adding wires might change the impedance, it didn't matter. You couldn't go far enough for it to matter. But when it came to video, it was a different story. The signal is a lot higher frequency, so the wavelength is shorter. While you might get by with a BNC 'T', this would cause a mismatch on the two splits and could result in some reflected signals.
