BoM and PCB Space Savings Achieved with Control Channel Aggregation for Optical Interfaces

Fibre optic networks bring the promise of fast broadband to new customers all around the world. It increasingly reaches new limits, but to provide a guaranteed level of service, that bandwidth must be managed effectively. A significant factor to that effectiveness is how it interfaces with other network equipment running over copper cable.
