Optical LNB - 03-June-2008, 15:05

Global Invacom has successfully tested an Optical LNB.
How it works:
The LNB distributes the four reception polarizations (vertical low and high band as well as horizontal low and high band) to four distinct frequency ranges.
Next, the RF signal is converted into a digital signal which is then sent through the optical cable via a laser beam. At the other end of the line this light beam is received by a converter box which reconverts the signal back into a regular satellite signal which can then be processed by any standard digital satellite receiver.
What this means for you and me :
With only a thin optical cable to run and the advantage of single cable installations for multi box set ups a lot less cable running around the house.
Also the optical cable has near zero loss over distance.
