Claim:
An optical cable assembly comprising the following: a plurality of optical fibers each having a first end and a second end, the plurality of optical fibers including a first group of optical fibers and a second group of optical fibers; a first connector head attached to the first end of the first group of optical fibers, the first group of optical fibers terminating in an array at a surface disposed on the first connector head, the first connector head including a first mating structure; a second connector head attached to the first end of the second group of optical fibers, the second group of optical fibers terminating in an array at a surface disposed on the second connector head, the second connector head including a second mating structure instable with the first mating structure, whereby the optical cable assembly is configured so as to be instable with another identical optical cable assembly so that polarity is maintained in each of the plurality of optical fibers across the optical cable assemblies; and at least two of the first connector heads, each of the at least two first connector heads being attached to a respective portion of the first group of optical fibers, and further including at least two of the second connector heads, each of the at least two second connector heads being attached to a respective portion of the second group of optical fibers.
