The optical power budget in a fiber-optic communication link is the allocation of available optical power (launched into a given fiber by a given source) among various loss-producing mechanisms such as launch coupling loss, fiber attenuation, splice losses, and connector losses, in order to ensure that adequate signal strength (optical power) is available at the receiver. In optical power budget attenuation is specified in decibel (dB) and optical power in dBm.
Signal processing apparatus, system and method
The present disclosure discloses a signal processing device, system and method, comprising: a first component and a second component; wherein the first component is configured to perform reflection broadening processing on the emitted initial optical signal to obtain a broadened optical signal; the second component is arranged in the optical signal transmission path of the first component and is configured to perform branching processing on the received broadened optical signal, and perform focusing processing on each optical signal after branching processing, and parallelly transmit each optical signal obtained by focusing processing to a corresponding terminal device; the reflection broadening, branching, focusing and parallel transmission of the optical signal are realized by the signal processing device, the power performance of the uplink optical channel is effectively improved, the demand for uplink optical power budget is reduced, and the device and network costs are further reduced.
