Military Aircraft To Get All-Fiber Network Gear

coondoggie writes "Looking to significantly reduce weight, improve on-board communications and make it easier to upgrade avionics, the US military is developing prototype phonic gear for use in all aircraft. Behind such a drastic shift is a Defense Advanced Research Projects Agency project with an ungainly moniker: Network Enabled by Wavelength division multiplexing Highly Integrated Photonics (NEW-HIP)."

      Not fighter jets, transport jets.

      There was a transport flying with a fighter escort. After many hours, the fight pilot called over to the transport pilot and said, "Watch this!" and proceeded to do some acrobatics.

      The transport pilot watched and then retorted, "Oh yeah! Watch this!"

      So the fighter pilot sat and watched. And watched. And watched. Then after 20 minutes, the fighter pilot called over again and said, "I'm still waiting to see what you can do?"

      The transport pilot said, "I did it. I got up, stretched my legs, went back for cup of coffee and talked to the flight engineer, went to the john -sitting down, grabbed another cup of coffee and walked back here."

      Ohh IDK about that.

      If some of the other western countries who often have some high tech gear of their own teamed up with some of the countries that have massive amounts of troops and resources. (Think England and France for the western countries, and China and India for the population size) I think we might have a heck of a problem.

      Not to say China doesnt have alot of high tech military gear, just that I think the sheer number of boots on the ground they could deploy is their big thing.

    Current prototype digital integrated transmitters are designed to support tuning over 32 wavelength channels, each carrying 10 gigabit-per-second data rates. The associated digital receiver can support the selection of any combination of four simultaneous outputs from the 32 channels.

    Assuming that a typical Cat5e cable can do about a Gbps, each of these cables are equivalent to about 30 cat5's. So unless these things weigh over 30 times what a cat5 does, they'll be significantly lighter.

      A wire is an antenna. A piece of copper isn't. Military electronics are hardened and then you attach a big antenna to them that can carry noise into your device. This is at least as much about protecting against anti-vehicle electronics as it is about saving weight.

      The real problem when installing this will be the LOSS of weight...specifically, the center of gravity for every single airframe will now have to be recomputed, and they will find that most of the wire is in the forward fuselage area (where most avionics are located). This means lead weights will have to be added to the forward section to balance out the loss of weight. I know, because I've already had to do it. We had a test F-111 in the early 90's configured with fiber optics. The conversion saved 650lbs of weight, but we had to add 400lbs of lead weights back in to preserve the CG.

    To put my point a different way: one of the big problems I see today is the refusal of the Federal government to just let failures fail. Look at the bailouts if you want examples.

    Speaking as a licensed electrical engineer that did the network cabling for my office, a matures shouldn't be doing it above the ceiling.

    Code issues: You need proper, dedicated support wires for the cables. Do you have Powder activated anchor gun... and proper training? Are you using plenum cables in the ceiling? Are you keeping the cables off the ceiling tiles?

    Practical issues: Are you pulling against any MC cable that you could pierce the armor and insulation with enough force? Are you going to cut yourself on any sharp metal? Are you wearing a hard hat and safety glasses above the ceiling so you don't get stabbed by other anchor wires? Can you spot asbestos?

    There are even simpler things... do you know how to safely use a ladder?

    Unfortunately, between workman's comp, risk of a lawsuit, and even general good practice, it doesn't really make good sense to have non-professionals pull cables. Now, if it wasn't for warranty issues, having your own tech do the terminations would be fine... but then how do you hold the other guy accountable for a pinched cable?
