Confusing information

. Thanks for all the information but some of it confuses me. It seems to
me that the first thing I have to do is to get a new Keyboard with a port
for my mouse.
Ok, that I understand. The part about the fiber optic cable I don't
understand. would it be possible to explain that part. I have never had to do
work on my computer and I'm not savvy about how to do things. I don't have
a friend who can help so I need easy directions for this problem which is
making me sick.

My new cordless phone has to go back and I 'll seek out an old phone. they
didn't bother me. I keep a cell just for emergencies and seldom use it so
it's not been a problem for me as yet.

Thanks

Estelle

Well, if you have a keyboard that uses a USB cable to connect the keyboard
to the computer, then the high frequency noise from the computer can
travel along the metal in the USB cable to the keyboard and mouse and
cause you problems. There exist USB cable extension cords which are
mostly made of fiber optics (converted back to regular USB cords at the ends),
which would NOT allow the noise from the computer to reach your keyboard
and mouse, as the noise cannot travel along the fiber optic portion of
the cable. Usually these are sold in very long lengths (more than 30 feet)
and cost a lot of money (more than $150). You would simply plug the
fiber optic USB extension into a computer USB port, and then plug your keyboard
into the other end.

Thank you all for making this clearer to me. I shall see what I can do to
remedy the situation. First, a new mouse, then a new keyboard with a USB
port to plug in the mouse.
Then, when I can manage the money, the fiber optic cable.

Anyone have success with a glove that is supposed to allow less
electricity coming through to my hand?

Thanks,,
Estelle

I also wonder if there are USB hubs that might be used to reduce the
noise from the computer? I assume there might be more expensive hubs
that filter the incoming inputs or regenerate the output signals
from scratch, that wouldn't pass on the noise to the keyboard and
mouse? But I have not looked into this, as my current computer
doesn't generate enough noise for my keyboard or mouse to bother
me. (just got lucky on that one)

USB includes power, so how do these work? Is there a battery at the end?

That's the thing that confuses me... I assume that both the DVI and the USB
fiber optic extenders must still be passing on the power via a metal wire
separately from the fiber optics, so there would still be an electrical
link to the computer. Although it was mentioned that some of these cables
are powered separately via a plug-in adapter.

I have seen some hubs that say they filter RFI or sometimes theyll say filters EMI (both are the same thing) , I have one thats not a hub but a usb extension that says it filters RFI I bought for like 20 dollars, I personallydidnt feel any noticeable difference with my symptoms.



There are 2 types of fiber optic cables.

One type is a Hybrid cable, this type of cable is powered by the computer at both ends so there is a thin copper wire inside only powering it but all the data and video signal which would carry most of the RF is passed through fiber optic cable. There is some RF by the computer that gets passed trough the power cable inside but it is very very little. This was the first cable I tried and I felt an enormous difference like 50% of my sypmptoms werereally reduced


The other type which is the one I use, uses only detacheable fiber optic cables between the transmitter and reciever. The transmitter can almost always powered by the computer so no adapter would be needed for it, but the receiver usually uses a small 2-5 volt adapter to power it. That is one very very small downside of these since the adapter does produce a little bit of RF which then gets transfered to the monitor but I put 2 ferrites on both ends of the power cable and I feel it reduced that by like 75%.






I am selling a hybrid DVi cable on ebay which I started the opening bid really low so it will sell low. I would really like a forum member to get it and report back theyre experience with it, Im offering free shipping and a 2week try out period in which if you dont want to keep it ill take it back and give you back a full refund.

I also have an extra set of the other type.

66 ft! Heh, heh... I only need about a 10 foot cable between my PC and
my monitor, but I put in a bid nonetheless... :-)

And selling is probably a safer option than lending... most of the time
when I lend something to someone on the Internet, I never see it again... :-(

You can hide the excess cable behind a desk or something or it might give you a chance to get even more distance away from your computer ;)
