摘要： A sourceless co-packaged optical-electrical chip can include a plurality of different optical transceivers, each of which can transmit to an external destination or internal components. Each of the transceivers can be configured for a different modulation format, such as different pulse amplitude, phase shift key, and quadrature amplitude modulation formats. Different light sources provide light for processing by the transceivers, where the light source and transceivers can be configured for different applications (e.g., different distances) and data rates. An optical coupler can combine the light for the different transceivers for input into the sourceless co-packaged optical-electrical chip via a polarization maintaining media (e.g., polarization maintaining few mode fiber and polarization maintaining single mode fiber), where another coupler operates in splitting mode to separate the different channels of light for the different transceivers according to different co-packaged configurations.

摘要： A ternary phase shift keying transmitter and receiver can efficiently communicate using ternary encoded data that avoids indistinguishable transition curves for each of the three modulated states in the ternary encoded data. The transmitter is interoperable and can function with different types of receivers including direct detection-based receivers and coherent detection-based receivers.

摘要： This disclosure pertains to the field of optical communications technologies, and relates to a signal processing method and apparatus. The method includes: receiving an optical signal in a target receive channel, and converting the optical signal into an electrical signal; determining, in the converted electrical signal, an electrical signal corresponding to a non-overlapping frequency band between the target receive channel and another channel, where the another channel is a channel that overlaps the target receive channel; and determining, based on the electrical signal corresponding to the non-overlapping frequency band, an electrical signal corresponding to a valid received optical signal that does not include an interfering optical signal in the target receive channel. In this disclosure, the target transmit channel and the another channel are set to channels that overlap each other, thereby reducing bandwidths occupied by the channels. Therefore, in the method provided in the embodiments of this disclosure, spectrum utilization can be improved, thereby improving a data transmission rate.
