Abstract: A system is disclosed for an improved ROSA that has increased sensitivity for permitting greater numbers of ONTs to be connected to an optical network per defined transmission line distances. The ROSA configuration includes a digital optical module with improved performance characteristics. This digital optical module has replaced a conventional photodiode with a PIN detector that is coupled with the TIA. The resulting digital optical module containing this PIN/TIA configuration when incorporated in a ROSA provides a single ROSA solution that will meet or exceed the ITU/IEEE FTTx standards for short and long distances under substantially all operating conditions.

Abstract: An integrated circuit product, for bidirectional communication, has two inputs and two outputs. The first input is located on a first edge of the integrated circuit product. The first output is located on a second edge of the integrated circuit product, the second edge being located adjacent to the first edge. The second input is located on a third edge of the integrated circuit product, the third edge being opposite the first edge. The second output is located on a fourth edge of the integrated circuit product, the fourth edge being opposite the second edge. The integrated circuit product can be mounted diagonally in a transceiver module, allowing straight signals paths from the inputs and outputs of the integrated circuit product to the corresponding inputs and outputs of the transceiver module.
