The interconnection characteristics of these two types of rearrangeable nonblocking EBN were studied  optical insertion loss of 4.6 dB  and the logic program for driving switching units was provided. The calculated insertion loss was 3.3 dB for 88 optical matrix switch. Silica waveguide 88 matrix optical switch was designed and fabricated according to the calculated results. The silica waveguide propagation loss of 0.1 dB/cm and waveguide-fiber coupling loss of 0.5dB/point were measured. With the fabricated 87times  cross-talk of -38 dB  polarization dependent loss of 0.4 dB  averaged switching power of 1.6 W  and switching time of 1 ms were achieved. A basic agreement between experimental results and theoretical calculated values was achieved.
