rtv> not sure how much code is needed for a VCSEL that converts electricity to photons and shoots them down a fibreoptic cable.
quite a lot, actually.
you'd be surprised.
here's a watered-down datasheet for one of Finisar's common 10-gig SFP+ modules.
to give you an idea, here's the DDMI spec for it -- a whopping 32 pages just to describe the monitoring functions!
it might sound easy at first glance, but "shovelling photons around" is a pretty complex thing once you've decided to roll up your sleeves to start working under the hood.
