To meet requirements for different service capacities, the OptiX OSN 3500 supports
two types of cross-connect board: GXCS (higher-order cross-connect capacity: 35G
and lower-order cross-connect capacity:5G) and EXCS (higher-order cross-connect
capacity: 60G and lower-order cross-connect capacity:5G).
