Cryo'd polymers
Posted by Duster on April 20, 2015 at 13:48:21:
IMHO, I doubt cryo treatment of borosilicate glass fiber optic material would be of benefit, but who knows if POF (Plastic Optical Fiber) might be. I would go on to wonder how cryo treatment might affect the cladding of an optical cable, too. I've read that polymers may benefit from cryo treatment for improved mechanical strength and resistance to wear, but how that may affect the performance level, one way or another of an optical cable is unknown to me. The only association of fiber optics with cryogenics I've come across is its use as a lead for temperature sensors. As a side note, cryogenic ampules are manufactured with borosilicate glass.
