Analysis and simulation of all-optical router for tdm-based optical networks using : NOLM

الملخص EN

The work in this paper addresses all-optical routers for TDM optical networks.

The core of the optical routers is the demultiplexer.

In this paper all-optical router is analyzed and simulated.

It is based on a TDM demultiplexer employing Nonlinear Optical Loop Mirror (NOLM).

Expressions are derived for the transmission and reflection coefficients for the loop mirror employed in the demultiplexer.

The effect of various system impairments, on the performance of the demultiplexer, such normal mode loss, control power, and losses, are addressed in details.

Simulation results were carried out using MATLAB 6.5 software.

The results indicate clearly that the demultiplexer should be designed precisely to achieve the required router performance.
