Patent ID: 8391726

Claim:
An optical receiver comprising: a frame detector configured to receive a polarized signal comprising a first bit stream and a second bit stream, and further configured to identify a plurality of frames in the first bit stream and the second bit stream using a composite header and a second composite header; and a time-domain equalizer (TDEQ) configured to separate the first bit stream and the second bit stream using a portion of the composite header, wherein the composite header comprises a first post-amble, a first header, and a first pre-amble, wherein the second composite header comprises a second-post amble, a second header, and a second pre-amble, wherein a first bit sequence is selected for the first header and a second bit sequence is selected for the second header, wherein the first header and the second header are distinguished using a cross-correlation function of the first bit sequence and the second bit sequence, wherein a third bit sequence is selected for the first pre-amble and a fourth bit sequence is selected for the first post-amble, wherein the first post-amble, the first pre-amble, and the first heading are detectable using an auto-correlation function of the first bit sequence, the third bit sequence, and the fourth bit sequence, and wherein a fifth bit sequence is selected for the second pre-amble and a sixth bit sequence is selected for the second post-amble, wherein the second post-amble, the second pre-amble, and the second header are detectable using an auto-correlation function of the second bit sequence, the fifth bit sequence, and the sixth bit sequence.
