It's acceptable when you find this term being mentioned in general forums, it's not when you see it on pro-audio forums (or "act-pro"-audio forums).
Oxygen-free copper, or OFC cables, cables made of high conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to .001% or less,
Is NOT a new thing in electronics or audio. In fact, I'd be surprised if I find a cable that is NOT made of OFC nowadays.
The big letters "OFC" on the reel, that is for the $1/m cable from my neighbourhood's DIY store (cost price: 10cents) to distinguish them from the 1cent ones, not for the $10/m "rated for audio" cables, and certainly not for the $100 speaker cables and interconnects.
So if you see a $100 cable with "OFC" as its feature, you know it's got nothing else worthy of marketing and nothing worth your money. It's like those overpriced and underpowered nettops that tout HD-playback capability, something that anything with a current-gen gfx processor or decent GPU can do, and give away the fact that without the built-in H.264 acceleration these things can't do shiat, they can't use FFDShow, and they suck at gaming.
So, if you ever see anyone talking about OFC cable as though it is something significant, do me a favour and shoot him.
You'd do the same without me telling if people talk about gold-plated connectors, rite?
