Optical Interface Lanes and Assignment
The optical interface port is a male MPO connector .The four fiber positions on the left as shown in the below Figure, with the key up, are used for the optical transmit signals (Channel 1 through 4). The fiber positions on the right are used for the optical receive signals (Channel 4 through 1). The central four fibers are physically present.
