Abstract
This paper presents a switching architecture for any large port number
optical cross connecting switch. We show the switching arrangement and the
construction process to realize mirror-type optical switches. The proposed
architecture refers to the Waksman network. Compared to other switching
architectures, this architecture uses a minimum number of mirrors. Four
guiding rules of the mirror arrangement method are proposed to assist
building up a large port number mirror-type optical switch in an efficient
way. By the analysis of all loss sources, the design parameters of the
mirror are identified. The expandability and feasibility are verified.
Furthermore, by an expert system, we can build up a lookup table to reduce
the control complexity. The generalized simulation results show that the
optical switch architecture of this paper is capable to archive the Bell
Communications Research (BELLCORE) specification requirements for low and
high port numbers.
