if I had to hazzard a guesstimation, a "balastics" glass would most likely be made of a material that when shot through, would have wide spread cracking, but not actally shatter, and if it did shatter, the compisite would be such that the instance of shards that could cut would be reduced.

Armored glass, again, as a guess, would be such that it would more try to stop the bullet, without the fracturing of the glass, instead leaving a slug in your window.

spotlite: It really is impossible to draw direct equivalents between SR Armor, Power and Barrier Ratings and what we have IRL. The first problem you run into is that, in SR, Heavy Pistols penetrate better than Assault Rifles, as well as heavy Sporting Rifles and Medium Machine Guns. This is so completely bass-ackwards that trying to make sense of any of the related figures is futile. Your approach to this seems very healthy.

Note that any APDS rounds, except for Hold-Out Pistols, will still penetrate a Barrier or Armor Rating of 10 and damage anything behind. IRL as well, to make something invulnerable to common armor piercing munitions from mid-power and weaker rifles and other weapons you'd need materials weighing more than twice as much per unit of area as the polyethylene plates I mentioned.

Well, there's some good things to think about there. Regarding the optic fibre length - I agree its completely unnecessary the vast majority of the time to have 100m of cable. But on the other hand, it means if you need cable for another job (perhaps you want to sit round the corner out of sight while your sequencer gets through that lock), its a relatively simple matter to take off the jack interface, cut the length you need and so on. Its a 'be prepared for anything' approach that the character has - which of course has its own pitfalls.

Firstly, fiber is a LOT thinner than cat-5. I'd say 1/4th-1/6th as thin width wise. Which makes the space in a spool that it takes up considerably smaller.

As far as just clipping off a length of fiber and using it, you've obviously never put an end connector on a fiber cable. First, you cut through all the insulation, then you have to carefully nick the fiber line and break it at the end, then sand it for a good 5-15 minutes to get a nice end on the glass. Lastly, you have to get your connector, and hook that on, crimp it to the insulation and the like, and then hope like hell you got a decent connection, test it, and if its bad, snip the whole thing again and start over (minus 2 inches). At least, thats by hand... tools required are scissors, fiber optic glass cutter, 3-5 different extremely high grades of sand paper (not available at the local hardstore type), a connector, crimp tool, testing tool, and the know how on how to do it.

I'm pretty sure there's no such distinction IRL. Armored glass just means any glass that happens to be resistant to attacks, ballistic glass refers to glass meant to protect against ballistic threats specifically.

Pics of bullets vs ballistic glass laminates
Interesting to note that 7.62x39mm FMJs aren't much better at penetrating this type of barrier than .44 Magnum SPs, even though the 7.62x39mm's penetrate body armor far better.

That's good, because I don't really want it invulnerable - where's the fun in that? Just enough that there's a better than good chance that regular ammo won't penetrate will do me just fine. I have a bullet barrier, sustaining foci and combat pool for dodging with for anything tougher, and a gyrojet pistol to make them keep their heads down while I flee like the wussy decker-mage that I am! To be honest, the rest of the team swanning around in milspec when they're on a job tends to draw fire away from me anyway. And *I'm* the only one with the distinctive style flaw! Sheesh.

Take your point about Real Life™ comparisons. We just go by the rules in the book except in this case where the rules just don't cover it and we have to go with guesses. Rather make an informed guess though given the choice!

As a techie that deals with Fiber, there is on flaw in the less space arguement, if you put the fibre into a loop under a certain diameter, it'll run the risk of shattering the glass. Of course, that's today's fiber optic cable, sixty years from now, I'd hope they could over come that limitation.
