Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is the flow chart for the fiber optic communication method for registering that the embodiment of the present invention one provides, and the present embodiment is applicable to The case where being registrated during fiber optic communication to optical transmitting set and photodetector, this method can be executed by controller, tool Body includes the following steps:
Step 101 sends handshake to K photodetector by N number of optical transmitting set.
Wherein, the N and K is the positive integer more than or equal to 1, N number of optical transmitting set and K light inspection Device is surveyed to connect by fiber array or free space non-matching formula.Wherein, the non-matching formula connection of free space can be true The aerial connection of non-matching formula or the connection of aerial non-matching formula.
Pass through the optical transmitting set and photodetector progress signal transmission that optical fiber both ends connect, existing skill during fiber optic communication It needs to be registrated optical transmitting set and photodetector before optical fiber is communicated in art, this programme takes software self-aligned manner It is registrated, rather than uses mechanical registeration mode in the prior art.Specifically, being sent in this step by N number of optical transmitting set Handshake is to K photodetector, when the advantage of the bigger this programme of the number of N and K is more obvious.Illustratively, in chip and Using during fiber optic communication between chip, a optical transmitting sets and photodetector up to a hundred are needed in a set of optic communication links It sends simultaneously or receives signal to complete information transmission.It illustratively, include the code sequence of optical transmitting set in the handshake Column, photodetector, which passes through the code sequence for including in the handshake received, can determine which light is the handshake be by Transmitter is sent, to be used for subsequent registration.Illustratively, which further includes field contents conventional in signal transmission, Such as signal type field, bandwidth and channel field, optical transmitting set and photodetector once complete software autoregistration, then subsequent The registration sequence that optical transmitting set and photodetector are indicated during communication signal transmissions, in signal of communication, according to the registration sequence Optical transmitting set and photodetector complete sending and receiving for signal.Wherein, the connection of non-matching formula is alternatively referred to as loosely connected, existing It needs for optical fiber, optical transmitting set and photodetector to be numbered in technology, and according to number rigid registrations to realize communication, this step The registration time in a large amount of scene and installation process can be saved using the connection of non-matching formula in rapid.
The signal strength pair of step 102, the handshake received according to each photodetector in the K photodetector N number of optical transmitting set and the K photodetector are matched.
In this step, K photodetector is matched according to the signal strength of the handshake of the optical transmitting set received.
