Multiple port network device with differential ports for reduced electromagnetic interference at optical modules
In one embodiment, an apparatus includes a plurality of optical module ports in communication with a physical layer device in a network device. Communication of signals from the physical layer device to the optical module ports is configured such that the signals received at the optical module ports adjacent to one another are at different phases to reduce electromagnetic interference associated with the optical module ports.
