The Space Station is at 14.7 PSI (sea level). It will boil at 373.15 Kelvin just like in Miami or Hawaii.

On some Cisco equipment you can tell it to ignore the non Cisco SFP's. In the Cisco Transport gear and large routers like the ASR9k you cannot use non Cisco SFP's. In fact Cisco transport gear won't use Cisco SFP's sold as router sfp's.
Comment Gallium Arsenide Cells Emit light when reversed (Score 1) 79
If you reverse the voltage enough on a Gallium Indium Arsenide solar cell it will glow red just like a diffuse light emitting diode. You have to remove the protection diode from the cell for that to work however.
Submission + - Researchers show-off high-speed laser communications device for space (networkworld.com)
coondoggie writes: Using lasers to communicate quickly through the long distances of space has generally been the purview of science fiction. But researchers at the National Institute of Standards and Technology (NIST) and NASA's Jet Propulsion Laboratory (JPL) are out to change that notion with a prototype array that can read more information — and allow much higher data rates than conventional systems — than usual from single particles of light. Lasers can transmit only very low light levels across vast distances, so signals need to contain as much information as possible, NASA said.

If you need precision you could use IEEE 1588v2 with or without synchronous Ethernet.
