For example, in a specific implementation process, an optical signal communication link may be constructed on an underlying physical link between two end devices; for example, the following modules may be preset in the underlying physical link of the two-end device: optical-to-electrical conversion, electrical-to-optical conversion, optical transmitters, optical receivers, optical sources, drivers, modulators, switched optical ports, photodetectors, amplifiers, related circuitry, optical repeaters.

EXAMPLE III
In order to make the first embodiment and the second embodiment clearer, the embodiment of the invention provides an optical link diagnotor, which mainly describes the interaction between the BBU and the RRU in a software module manner; in the specific implementation processes of the first embodiment and the second embodiment, the corresponding technical details may refer to the present embodiment; the diagnosis device is an RRU fault analyzer which automatically diagnoses an optical link by means of a special low-speed channel under the condition of BBU-RRU broken link, and the diagnosis device is mainly realized by simulating a UART through CPUs on two sides of the BBU and the RRU in the transmission process of diagnosis information.
For example: and the BBU establishes and maintains a monitoring task for uploading the broken link information of the RRU, and the RRU receives an initial signal sent by the RRU after the broken link to complete the receiving and storing of the RRU diagnosis information.
The BBU receives bit data by detecting light and non-light signals, and reduces bit flow into bytes according to data coding rules and frame formats agreed by the BBU and the RRU to obtain RRU diagnosis information.
After receiving the message of data reading by the network manager, the BBU comprehensively diagnoses the RRU after chain breaking, BBU diagnostic information and diagnostic information on both sides before chain breaking, and then transmits result information (optical link diagnostic information) to the NMC network manager, and the NMC network manager presents the diagnostic result.
In detail, the diagnosis device in the embodiment of the present invention may include an RRU diagnosis module, an RRU optical module, a BBU alarm acquisition module, a BBU diagnosis module, a BBU optical module, an NMC alarm monitoring module, and a diagnosis information display module. The concrete implementation of the parts in the network is illustrated in fig. 3. Wherein:
an RRU optical module: and the optical-electrical conversion module is responsible for optical-electrical conversion and is used for transmitting modulated optical signals with corresponding rates, and simultaneously converting the optical signals sent by the BBU side into electrical signals. And under the condition of chain breakage, the RRU diagnosis information is transmitted to the BBU in a mode of continuously switching the optical port.
An RRU diagnosis module: the method is operated on the RRU and used for collecting RRU diagnosis information including the problems of over-temperature, over-distance, over-speed rate and over-large light attenuation of an optical module, and the judgment basis is as follows:
ultra-mild and excessive light decay: the local terminal obtains the state information of over-temperature and over-low receiving power, and the receiving power of the optical port is over-low and is equivalent to over-large light attenuation to a certain extent.
Criterion of excessive light attenuation: acquiring digital diagnostic information of an optical module, receiving power P (RX) of the current (receiving side) optical module, output power P (TX) of an opposite-end (transmitting side) optical module, and solving R1 (P (TX) -P (RX) -1dBm (two pairs of fusible fiber plugs). And calculating the fiber loss R2 (the fiber length L is 0.5dBm (attenuation per KM) according to the fiber length, and judging that the optical attenuation of the optical link is too large if R1< R2. The optical fiber distance measurement is not supported, and the light attenuation is not too large.
Over-distance and over-speed: and the home terminal acquires the distance and speed information, performs optical fiber distance measurement and simultaneously acquires the optical port speed configured by the OMC server.
And (3) over distance judgment: the value of the fiber range value is greater than a preset multiple of the single mode transmission distance, and the over-distance is considered to be used, for example, 1.5 times. For the case where fiber ranging is not supported, it is considered that no over-distance is used. And if the RRU side is over distance, comparing the transmission distance by using the RRU side optical module with the result of BBU side optical fiber distance measurement.
And (4) overspeed judgment: using the optical module support range table given by the hardware, actually measuring and adjusting, for example:
a. the nominal 10G optical module allows the use of the rate: 6.144G-10.1376G
b. The nominal 6G optical module allows the use of the rate: 2.4576G-6.144G
BBU optical module: and the optical-electrical conversion module is responsible for optical-electrical conversion and is used for transmitting modulated optical signals with corresponding rates, and simultaneously converting the optical signals transmitted by the RRU side into electrical signals. In the case of a broken link, information (e.g., a diagnostic request) is transmitted to the RRU by continuously switching the optical port.
A BBU diagnostic module: the system runs on the BBU and is used for collecting BBU diagnosis information, the BBU sends a diagnosis request under the condition of broken optical link, starts to collect RRU optical port information in a low-speed channel and regularly polls whether the collection is finished, and replies NMC network management diagnosis failure if the polling collection fails; and if the polling is successful, calling an internal interface to obtain RRU diagnosis information, and organizing a response message to reply to the network manager.
BBU warning acquisition module: the system runs on the BBU and is used for detecting BBU-RRU broken link alarm. And under the condition of optical link disconnection, calling a BBU diagnosis module to obtain diagnosis information of BBU and RRU sides including the optical link, namely obtaining the optical link diagnosis information of the optical link disconnection, giving specific criteria, reporting an optical link disconnection alarm, carrying an instructive conclusion, adding the instructive conclusion into the alarm information, and reporting the alarm information to an NMC network manager. When the BBU and the RRU are connected by multiple optical fibers, the alarm is hung under the optical port on the side of the BBU, so that the RRU optical port information connected with the optical port only needs to be acquired.
The processing flow of the diagnostic device is shown in fig. 6, and includes the following steps:
step 301: when the BBU alarm acquisition module detects that the fault of the optical port receiving link jumps from False to True, triggering collection of BBU-RRU optical link diagnosis information;
step 302: the BBU collects the over-temperature, over-distance, over-speed and over-light attenuation state information of the optical port of the local terminal, and starts a polling timer to collect the over-temperature, over-distance, over-speed and over-light attenuation state information of the optical port of the butt RRU through a low-speed channel;
step 303: if the polling collection fails, organizing a BBU side diagnosis conclusion and reporting the BBU side diagnosis conclusion as an additional text to the OMC server; the polling is successful, RRU side information is obtained, a complete BBU-RRU optical link diagnosis conclusion is organized, and the information is reported to an OMC server as an additional text;
step 304: the OMC server reports the alarm to the NMC, after the alarm monitoring module of the NMC observes 'RRU broken link alarm', the operation and maintenance personnel can obtain conclusive guidance opinions from the alarm additional information, if the original data supporting the diagnosis conclusion is further obtained, the alarm is selected, and 'RRU fault analysis' is executed;
step 305: the NMC server sends the RRU fault analysis request to the OMC server, and the OMC constructs a BBU-RRU link diagnosis request and sends the BBU-RRU link diagnosis request to the BBU;
step 306: the BBU diagnosis module collects the original diagnosis data of the local optical interface and the butted RRU optical interface through the low-speed channel, and the data can assist the optical link fault location, including:
optical port position, optical fiber ranging, optical port configuration rate, normal serial rate, (9um) single-mode fiber km-level transmission distance, (9um) single-mode fiber 100 m-level transmission distance, manufacturer name, device model, laser wavelength, transmission rate deviation upper limit, transmission rate deviation lower limit, device bar code, production date, digital diagnosis type supported, transceiver temperature, transceiver voltage value, TX bias current, TX transmission power, RX receiving power, remote equipment model, remote equipment complete machine SN, remote equipment large version number, remote equipment last reset reason, remote equipment input voltage and remote equipment LCV error code accumulation.
Step 307: the BBU diagnosis module returns the collected diagnosis original data to the OMC server, the OMC server further returns the collected diagnosis original data to the NMC, and operation and maintenance personnel can check the diagnosis original data in the NMC diagnosis information display module to assist in checking the optical link fault.
