Sort of, but not directly. Ethernet and fast-ethernet have minimum cable lengths specified. There is no minimum cable length specified for gigabit ethernet (1000BASE-T). For gigabit ethernet, what matters is that none of the crosstalk parameters are exceeded. So, any length of cable *as long as it certifies as CAT5e/6/6A* will work for gigabit ethernet. In practice, you'll find good CAT6 1m patch cables readly available, I've never seen anyone bother selling anything shorter than that, but YMMV. -- Henrique Holschuh
