Connecting 2 Focusrite OctoPe Mk2's To Motu 828 Mk3

Hi all. Just wondering what the best way would be to slave 2 Focusrite OctoPre Mk2's to a MOTU 828 Mk3 as far as the word clock goes. Octopre has 2 optical outs, and 1 word clock in. 828 has 2 pair of optical ins & outs, and word clock in & out. Could I get away with using a BNC "T" adapter?

Thanks,
Bill
