The OLP (optical line protection unit) module is an alternative optical path control switch in hardware, and the position of the switch can be controlled by software to control the switching of the main and standby optical fibers.
As shown in fig. 3, there are two Open-WDM (semi-active wavelength division device) trunk fibers, named: primary optical fiber (primary) and protective optical fiber (second), which are formed by combining waves of AAU (Active Antenna Unit, Active Antenna processing Unit) of opposite terminal, wherein the AAU is the main equipment of 5G base station and is the implementation scheme of large-scale Antenna array; after reaching local side equipment, after passing through an OLP (optical line protection unit) switch, a primary optical fiber channel reaches an Active line and is subjected to splitting to obtain r _1, r _2, a.
Some of the designations appearing in the present invention are to be construed as:
WDM: wavelength division multiplexing is a technique in which optical carrier signals (carrying various information) with two or more different wavelengths are combined together at a transmitting end via a Multiplexer (also called a Multiplexer) and coupled to the same optical fiber of an optical line for transmission.

OPM, optical power measuring module;
the AAU, the active antenna unit, is the primary device of the 5G base station, which is an implementation of a large-scale antenna array.
The invention is further illustrated in detail by the following specific application examples:
as shown in fig. 5, a method for protecting and controlling 5G forwarding devices according to an embodiment of the present invention includes the following steps:
step S10, in the 5G forward-transmission networking system, a semi-active wavelength division device sets a main fiber and a standby fiber on a trunk line of fiber transmission to protect each other; the main and standby optical fibers are respectively a main optical fiber and a protection optical fiber;
in the embodiment of the present invention, as shown in fig. 3, in a 5G fronthaul networking system, a semi-active wavelength division device sets a main trunk line for optical fiber transmission with a main optical fiber and a standby optical fiber for mutual protection; the primary optical fiber and the secondary optical fiber are primary optical fiber (primary) and protective optical fiber (second), and are respectively connected between an OLP (optical line protection unit) and a 1:2 optical splitter.
Of course, the present invention requires, before its implementation:
in a 5G forward-transmission network, setting the switching conditions of the main and standby optical fibers in advance, wherein the switching conditions comprise automatic switching and command switching; the automatic switching is to control the switching of the main and standby optical fibers according to the preconfigured optical branch monitoring conditions, and the preconfigured optical branch monitoring conditions in the automatic switching state include: monitoring part of the light branches after the division or monitoring all the light branches;
wherein the monitoring of the optical branch channel state comprises: an Idle state that the optical power of the optical path is in a normal working range and a Fail state that the optical power of the optical path is lower than a set threshold.
For example, when monitoring whether the optical power of a specified optical branch is within a specified channel threshold range, if yes, the optical branch is represented as an Idle state in which the optical path works normally; and if the detected light power is lower than the respective set channel threshold, judging that the branch is in an abnormal Fail state.
The command switching in the invention is to control the switching of the main and standby optical fibers according to the set command. The pre-configuring the command switching instruction comprises: the control commands of forced switching, manual switching and switching clearing are set, the corresponding relation between the control commands of forced switching, manual switching and switching clearing and the corresponding execution operation commands is established, and the priority of command switching command execution is set to be higher than that of the automatic switching state execution command. The user can conveniently input the corresponding command switching instruction to carry out command switching in the maintenance process.
Step S20, 5G, the forwarding networking system starts to operate, and the default state is controlled to be an automatic switching state;
in the embodiment of the present invention, referring to fig. 3, when the 5G forwarding networking system starts to operate, the default state is controlled to be the automatic switching state, and step S30 is performed.
Step S30, monitoring the optical branch channel state according to the preset optical branch monitoring condition in the automatic switching state, and controlling the switching of the main and standby optical fibers according to the monitored optical branch channel state;
in the specific implementation of the present invention, referring to fig. 3, when the 5G fronthaul networking system is in the automatic switching state, the optical power real-time monitoring module (OPM) monitors the optical branch channel state in real time;
if the channel state of the primary optical fiber (primary) is an Idle state with a normal optical path and the channel state of the protected optical fiber (second) is a Fail state with an abnormal optical path, the current selector (i.e. the optical line protection unit OLP) selects to switch the primary optical fiber (primary) channel to an Active state; i.e. the switch of the optical line protection unit OLP is turned up as shown in fig. 3.
If the channel state of the primary optical fiber (primary) is a Fail state with an abnormal optical path and the channel state of the protection optical fiber (second) is an Idle state with a normal optical path, the current selector (i.e. the optical line protection unit OLP) selects to switch the protection optical fiber (second) channel to be an active state; i.e. the switch of the optical line protection unit OLP is turned down.
If the channels of the primary optical fiber (primary) and the protection optical fiber (second) are both in Idle state with normal optical path, the position of the current selector (i.e. the optical line protection unit (OLP)) remains unchanged;
if the primary optical fiber (primary) and the protection optical fiber (second) are both in the Fail state with abnormal optical paths, the current position of the selector (i.e. the optical line protection unit OLP) remains unchanged.
Step S40, when receiving the operation instruction of command switching, controlling switching of the main/standby optical fibers according to the operation instruction of command switching.
In this step, when an operation instruction for command switching is received, the position of the optical switch of the optical line protection module is determined according to the target channel specified by the operation instruction for command switching and the states of the current primary optical fiber (primary) and protection optical fiber (second) lines.
The process of the invention is described in further detail below:
the method for monitoring the states of the primary optical fiber (primary) line and the protective optical fiber (second) line in the embodiment of the invention comprises the following steps:
the light path state is divided into Idle and Fail. Idle indicates that the optical path works normally, Fail indicates that the optical power of the optical path is low and is lower than the set threshold. Namely, the monitoring of the optical branch channel state in the invention comprises: an Idle state that the optical power of the optical path is in a normal working range and a Fail state that the optical power of the optical path is lower than a set threshold.
The main optical fiber is formed by multiple paths of light with different wavelengths, and the optical power monitoring is to measure the light with a specific wavelength. As shown in fig. 3, the optical path of the Active line is divided into r _1, r _2, r _ n branches by WDM (wavelength division multiplexing), each branch can independently detect optical power, and when the optical power is lower than the respective set channel threshold, the branch is determined to be Fail (indicating that the optical power of the optical path is low and lower than the set threshold); the state of the Active line is determined by all branch states by default, or by selecting part of branch states according to user configuration, and when all the set branch states are all Fail, the Active line is determined to be Fail (indicating that the optical power of the optical path is low and lower than the set threshold); as long as there is a set branch channel state as Idle, the Active line is considered as Idle (indicating that the optical path is working normally).
The Standby line directly enters an OPM (optical power real-time monitoring) module for detection, when the optical power of the Standby line is lower than a set threshold of the Standby line, the Standby line is judged to be Fail (indicating that the optical power of the optical path is low and lower than the set threshold), and otherwise, the Standby line is Idle (the optical path works normally).
According to the position of a switch in an OLP (optical line protection unit) module, the states of Active and Standby are corresponding to primary (primary optical fiber) and secondary (protection optical fiber) lines, and the states of the primary (primary optical fiber) line and the secondary (protection optical fiber) line are obtained.
The working modes of the system in the application comprise: automatic mode (Auto), Force mode (Force), Manual mode (Manual). In Auto mode, the system automatically determines the position of an OLP (optical line protection unit) optical switch according to the states of a primary line and a secondary line.
Under the Force mode (Force) and the Manual mode (Manual), the position of the OLP optical switch is determined according to the target channel specified by the command issued by the user and the states of the current primary and secondary lines.
In the running process of the 5G forward transmission equipment, the invention can also issue the command switching instruction to the equipment at any time.
In the embodiment of the invention, an alternative selector, called a logic selector, is realized through a software control layer, and corresponds to an OLP control module in hardware, and software determines the position selected by a switch in the logic selector according to the working states of primary and secondary and the current working mode of a system. The position of the hardware OLP switch is refreshed according to the position of the switch in the logic selector.
The rule of automatic switching in this application is:
if primary optical fiber state is Idle (optical path working normally) and secondary (protection optical fiber) channel is Fail (indicating that optical power of optical path is low and lower than set threshold), selecting primary channel as Active (Active state);
if the primary fiber channel state is Fail (the optical power is lower than the respective set channel threshold), and the secondary (protection fiber) channel is Idle (the optical path works normally), selecting the secondary (protection fiber) channel as Active (Active state);
if primary and second channels are Idle (optical path works normally), the current selector position remains unchanged;
if primary and second channels are both Fail (optical power is lower than the respective set channel threshold), the current selector position remains unchanged;
in this embodiment of the present application, if an operation instruction for command switching is received, the rule of command switching is:
the command switching includes: clear command, Force command, Manual command. The priority is as follows: clear command > Force command > Manual command.
When the system receives that the command switching operation instruction input by the user is a Clear command, the current command mode (Force or Manual) is controlled to be cleared, the system returns to the automatic protection mode, the current working mode is changed into Auto, and the position of the selector is refreshed again.
When the system receives the operation command of command switching as a Manual command, the control brings a parameter to indicate which channel to manually switch to. If the current working mode is Force, the switching is unsuccessful; if the state of the target channel is Fail, the switching is unsuccessful; otherwise, the switching is successful, the position of the selector is changed into the position of the target channel, and the current working mode is changed into Manual.
When the system receives the command switching operation instruction, namely Force command switching, a parameter is brought in to indicate which channel is to be forcibly switched to, the switching can be successful no matter the state of the target channel is Idle or Fail, the position of the selector is changed into the position of the target channel, and the current working mode is changed into Force. The Force command may override the Manual command.
Summarizing the overall switching control flow of the system of the present invention is shown in fig. 6:
the total protection of the invention is divided into automatic switching and command switching, the automatic switching can be configured by the user with the monitoring range of the optical path, and part of the optical branches after the division can be selected for monitoring, and all the optical branches can also be monitored; the command switching is further divided into control commands such as forced switching, manual switching, switching clearing, etc. Flexible control requirements during field networking application are met;
