Patent ID: 7412122

Claim:
A fiber optic communication system, comprising: (a) a first module comprising a first transceiver chip cast on a first single die, the first die comprising a first plurality of receivers in a first receiver region, a first plurality of transmitters in a first transmitter region, and a first spatial separation region having a first plurality of n-type and p-type sub-regions operable to electrically isolate the first transmitter region from the first receiver region, the first separation region being disposed between the first transmitter region and the first receiver region, the first plurality of n-type and p-type sub-regions being disposed on the first single die in alternating first horizontal rows; (b) a second module comprising a second transceiver chip cast on a second single die, the second die comprising a second plurality of receivers in a second receiver region, a second plurality of transmitters in a second transmitter region, and a second spatial separation region having a second plurality of n-type and p-type sub-regions operable to electrically isolate the second transmitter region from the second receiver region, the second separation region being disposed between the second transmitter region and the second receiver region, the second plurality of n-type and p-type sub-regions being disposed on the second single die in alternating second horizontal rows; (c) a fiber optic communication link operably coupling the first module to the second module; and (d) a first communication device operably coupled to the first module and a second communication device operably coupled to the second module, the first and second communication devices being operably connected to one another to effect communication therebetween through the first and second modules.
