The Lark 850 is a uni-directional 8 x 112Gb/s Digital Signal Processor (DSP) IC that is optimized for Linear Receive Optics (LRO). In an LRO transceiver or Active Optical Cable (AOC), only the transmit path from the electrical input to the optical line side output includes a DSP for signal retiming and equalization.

The Lark 850 based optical transceiver addresses the inherent weakness of a Linear Pluggable Optics (LPO) implementation by facilitating IEEE compliant optical transmit signaling and easing the deployment burden on system operators by eliminating manual, per port tuning.
