摘要
本文讨论了在４×４网结型完全无阻塞光开关阵中，构成４×４重排无阻塞光开关阵的组合数。由分析计算可得到４８种组合。文中把这些组合一一列出。结果表明，当一个４×４网结型开关阵的１６个开关中有若干个失效时，有可能把这个开关阵变成一个４×４重排无阻塞开关阵。
In this paper, we discuss the numbers of 4× 4 rearranging nonblocking optical switch matrices formed in a 4 ×4 strictly nonblocking net-type optical switch matrix. By theoretical calculation, 48 kinds of them are obtained and listed. The result shows that if some of optical switches in a 4× 4 strictly nonblocking switch matrix do not work, it is possible to transfer the matrix to a4 × 4 rearranging nonblocking matrix.
