The problem with writing reviews about products you love is that you can jinx them. At least that’s what I discovered after covering the CYP Puma PU-106/107. I had used a pair of these to run HDMI video over a single CAT6 cable. However, after six weeks they died on me. I bought the CYP 108 and, then, after a couple of months, it died on me, too.
So, suffice to say, I think that the CYP have quality control issues. But I needed to find a solution, because I had a cable TV installation that I needed to transmit to a basement and there was no way that I’d be able to drop a suitable BNC cable down there. In fact, I learnt a lot more about cable and satellite than I ever wanted to. It seems that CAT6 cannot support the signal bandwidth required to transmit what comes down a cable/satellite cable from the street/roof. Consequently, there is no such thing as a transceiver for this signal over CAT6. So, I was back to square one. I needed an HDMI to CAT6 transmitter/receiver kit, if I had any hope of getting video from my cable installation down there.
After doing some research, I went with the Octava CAT5/6 extender. One of the reasons I chose it in the end is that it uses 2 CAT5/6 cables instead of one. This may sound like a step backwards but, frankly, HDMI is really fiddly and you increase your problems when you try to get it down a single CAT5/6 cable. One reason for this is that the signal becomes more susceptible to problems the longer your cable is. And, if you terminate your cables into punch-down blocks before connecting them to your equipment with additional leads, then you compound the problem. At the end of the day, you can increase the length of your run and get away with lesser quality cable if you use two instead of one.
I’ve been using the Octava for over a month and so far so good. It isn’t completely trouble-free. The other day, there was snow on the TV and intermittent picture and sound problems. I went to the transmitter, pulled out the power cable, waited five seconds and then put the power back in. The problem went away. Not the end of the world but somewhat irritating.
I guess that, for the time being, there really isn’t a trouble-free solution. Nevertheless, if you have a similar situation to mine, you don’t have a choice. I’ll keep you posted if I have any problems but, for now, I’d recommend you put your money on Octava – rather than CYP.
One handy thing about the Octava – as opposed to the CYP hardware – is that it only needs power at the transmitter end. The receiver gets power from the CAT5/6 cables that you are using. This removes the need to plug it into the wall where the TV is.
