Abstract
An optical backplane assembly (1) includes a backplane (10), a first switch card (21), a second switch card (22) disposed on one side of the first switch card, a plurality of first line cards disposed on the other side of the first switch card, and a first optical assembly (41) including a plurality of first optical channels (411) and a plurality of second optical channels (412) overlapped with the first optical channel. The first optical channels optically interconnecting the first switch card with the first line cards. The second optical channels optically interconnecting the second switch card with the first optical channels.
