| At work I have twin 808nm 5W lasers that each launch into a 100 micron core multimode fiber. 100 feet of fiber later, the fibers are coupled into a module that converts the light back into electricity. It's a similar concept to power of ethernet but using light. The unit I have is a custom assembly made by JDSU and can power up to 2W at 12 volts DC in a remote location. Just thought it was cool and didn't know if anyone had ever heard about it. |

That is the same as fiber optic communications that have been used for about 10 years not. I have trouble believing that it is 808nm. Most telecom signals are 850, 915, 1310, 1460, or 1550mW with small variances in wavelength.

To LaserBen - He DID say it was custom made... Instead of sounding harsh, couldn't you have asked why the odd number? I honestly don't know much about lasers as I just got into these fascinating tubes of magnificent light, so I wouldn't know anyhow.
To Krutsch16 - Since LaserBen failed to ask, I will. Is the odd number of the width due to some testing that your company is performing? Maybe to get the most out of a smaller beam? I'd be interested to know.  |
