Abstract:
1. A method comprising: establishing a plurality of transmission time slots, each time slot corresponding to one of a plurality of optical transmitters coupled to a head end via an interleaving device; forming a bit interleaved optical data stream at the interleaving device based on a plurality of optical bits transmitted by the plurality of optical transmitters during a respective time slot associated with each of the optical transmitters, each of the optical transmitters transmitting only one optical bit to the interleaving device within each respective time slot, wherein each time slot has a duration of 10 nanoseconds (ns) and each optical bit is transmitted via a pulse having a pulse width of 2.5 ns; and transmitting the bit interleaved optical data stream from the interleaving device to the head end over an optical network, wherein a peak power of each pulse is higher than a predetermined threshold that would cause human eye damage while an average power of pulses in the bit interleaved optical data stream is below the predetermined threshold.
