You're absolutely correct ... it's been a long time since I was designing fiber transceivers but I should have remembered this. Ultimately efficiency is also affected by other layers of the protocol stack too (UDP versus TCP headers) which also explains why larger frames can be more efficient. In the early days of RTP and RTSP, there were many discussions about frame size, how it affected contention and prioritization and whether it actually helped to have super-frames if the intermediate networks were splitting and combining the frames anyway.
