Description
本公开涉及光通信技术领域,特别是涉及一种多模式调顶信号的发送和接收方法、发送和接收***。The present disclosure relates to the field of optical communication technology, and in particular, to a method and a transmission and reception system for transmitting and receiving multi-mode topping signals.
当前的5G前传网络要求高带宽、低时延和低成本,由于5G基站的覆盖范围小,因此相比4G基站需要增加更多的基站数量和密度,对基站的光纤数量带来了极大的需求。而随着新光纤布放成本的增加,原有网络光纤资源的匮乏,无法满足光纤资源的需求。因此,业界提出了12个波长的半有源前传方案Open-WDM(Open Wavelength Division Multiplexing,波分复用),其中以***的MWDM和中国电信的LWDM方案为主,为了实现远端光模块的管理,半有源前传光模块采用了纯调幅ASK和多载频调幅ASK两种调顶方法。多载频调幅方式针对每个不同的波长,分配不同的载波频率,这样在主干光纤上,当12个波长同时工作时就可以采用同一个光探测器PD根据不同的频率来识别不同的波长。The current 5G fronthaul network requires high bandwidth, low latency and low cost. Since the coverage of 5G base stations is small, more base stations need to be added in number and density than 4G base stations, which has a great impact on the number of optical fibers in the base stations. need. As the cost of new optical fiber deployment increases, the original network optical fiber resources are scarce and unable to meet the demand for optical fiber resources. Therefore, the industry has proposed a 12-wavelength semi-active fronthaul solution Open-WDM (Open Wavelength Division Multiplexing, wavelength division multiplexing), among which China Mobile's MWDM and China Telecom's LWDM solutions are the main ones. In order to realize the remote optical module For management, the semi-active fronthaul optical module adopts two top-adjusting methods: pure amplitude modulation ASK and multi-carrier frequency amplitude modulation ASK. The multi-carrier frequency amplitude modulation method allocates different carrier frequencies to each different wavelength, so that on the trunk fiber, when 12 wavelengths work at the same time, the same photodetector PD can be used to identify different wavelengths based on different frequencies.
当前的半有源前传方案采用纯调幅调顶方案时,不能在主干光纤上监控每个波长的状态。当采用多载频调幅方案时,可以在主干光纤上采用同一个PD来同时监控12个波长状态。虽然多载频调幅有一定的功能优势,但具体实现的时候会带来硬件电路和软件的复杂度提高问题,导致成本和技术门槛的提高,影响产业链的普及。并且,纯调幅和多载频调顶的硬件电路和软件有所不同,生产加工时需要采用不同的PCBA(Printed Circuit Board Assembly,印刷电路板组件)和元件表来实现,造成产品型号的增加和库存的压力,不利于成本的降低。在网络应用的时候,改变调顶方式时还需要到现场更换光模块,影响正常业务,维护成本增高。另外,目 前Open-WDM的调顶速率仅有1Kbps,速率较低,无法支持更大容量的数据交互,交互实时性也较差,不能满足有些场景下几千Kbps的高速率需求。When the current semi-active fronthaul solution adopts a pure AM topping solution, the status of each wavelength cannot be monitored on the trunk fiber. When using a multi-carrier frequency amplitude modulation scheme, the same PD can be used on the backbone fiber to monitor the status of 12 wavelengths at the same time. Although multi-carrier frequency amplitude modulation has certain functional advantages, the specific implementation will bring about increased complexity of hardware circuits and software, leading to an increase in costs and technical thresholds, and affecting the popularization of the industry chain. Moreover, the hardware circuits and software of pure amplitude modulation and multi-carrier frequency modulation are different, and different PCBA (Printed Circuit Board Assembly, printed circuit board assembly) and component tables need to be used during production and processing, resulting in an increase in product models and Inventory pressure is not conducive to cost reduction. In network applications, when changing the top adjustment method, you need to go to the site to replace the optical module, which affects normal business and increases maintenance costs. In addition, the current top-down rate of Open-WDM is only 1Kbps, which is low and cannot support larger-capacity data interaction. The real-time interaction is also poor and cannot meet the high-speed requirements of several thousand Kbps in some scenarios.
鉴于以上情况,如何克服现有技术所存在的缺陷,解决上述技术问题,是本技术领域待解决的难题。In view of the above situation, how to overcome the shortcomings of the existing technology and solve the above technical problems is a difficult problem to be solved in this technical field.

光模块***设备之后,设备通过I2C1接口与光模块MCU1进行通信,监控光模块的工作状态,调整配置光模块的工作参数,对于调顶光模块还可以发送和接收调顶数据帧。第二微控制单元MCU2的调顶机制通过设备主CPU进行配置,然后存储在第一微控制单元MCU1中,再通过第一微控制单元MCU1与第二微控制单元MCU2的数据接口将配置发送到第二微控制单元MCU2。大多情况下,调顶机制配置完成后中途不做改变。本实施例中,用户也可以根据需要,在中途按需改变调顶机制,例如从纯调幅ASK改变为多载频调幅ASK,或者从多载频调幅ASK改变为调频FSK。After the optical module is inserted into the device, the device communicates with the optical module MCU1 through the I2C1 interface, monitors the working status of the optical module, adjusts and configures the working parameters of the optical module, and can also send and receive top-level data frames for the top-level optical module. The top adjustment mechanism of the second micro control unit MCU2 is configured through the main CPU of the device, and then stored in the first micro control unit MCU1. The configuration is then sent to the computer through the data interface between the first micro control unit MCU1 and the second micro control unit MCU2 The second micro control unit MCU2.

In this embodiment, the user can also change the top adjustment mechanism midway as needed, such as changing from pure AM ASK to multi-carrier AM ASK, or from multi-carrier AM ASK to frequency modulation FSK.
本实施例的多模式调顶基本工作过程如下:光模块上电初始化完成之后,默认工作在某种调顶模式。例如默认工作于纯调幅ASK。设备主CPU通过I2C1接口可以把调顶模式配置成多载频调幅ASK或调频FSK模式。在调顶模式配置完成之后,第二微控制单元MCU2就开始按照选定的模式发送和接收调顶信号。其中,多载频调幅的方式是在发送幅度1的时候,把一个指定频率的波形和幅度进行叠加,通过包络幅值来表示幅度1。调频FSK的方式具有更好的工作稳定性和抗干扰能力,该调频方式采用不同的频率来表示数字的0和1,例如1KHz频率表示数字0,10KHz频率表示数字1。The basic working process of the multi-mode top adjustment in this embodiment is as follows: after the optical module is powered on and initialized, it works in a certain top adjustment mode by default. For example, it works on pure AM ASK by default. The main CPU of the device can configure the top adjustment mode to multi-carrier frequency amplitude modulation ASK or frequency modulation FSK mode through the I2C1 interface. After the top-adjustment mode configuration is completed, the second micro-control unit MCU2 starts to send and receive top-adjustment signals according to the selected mode.

在本优选实施例中,所述微控制单元包括幅度/频率处理模块以及调顶数据解码恢复模块,其中,所述幅度/频率处理模块用于根据配置的调顶模式来鉴别幅度、包络大小、频率数值中的一种或多种;其中,调顶模式包括纯调幅ASK模式、多载频调幅ASK模式以及调频FSK模式中的一种或多种;所述调顶数据解码恢复模块根据幅度/频率处理模块的鉴别结果来解码恢复出原始调顶数据。In this preferred embodiment, the micro-control unit includes an amplitude/frequency processing module and a top-adjusted data decoding and recovery module, wherein the amplitude/frequency processing module is used to identify the amplitude and envelope size according to the configured top-adjusted mode. , one or more of the frequency values; wherein, the topping mode includes one or more of the pure amplitude modulation ASK mode, the multi-carrier amplitude modulation ASK mode and the frequency modulation FSK mode; the topping data decoding and recovery module is based on the amplitude /The identification result of the frequency processing module is used to decode and recover the original topping data.
下面说明该***的多模式调顶接收(RX)功能:如图8所示,在调顶接收方向,高速探测器PD将光信号转换成电信号,高速数据电信号直接送入驱动芯片的接收端。慢速调顶信号从高速探测器PD的光电流监控引脚输出,送到调顶模拟信号提取单元。在提取单元,微弱的调顶信号根据调顶模式,通过放大器进行放大,滤波后提取,然后送到第二微控制单元MCU2的幅度/频率处理模块。根据原先配置的调顶模式,幅度/频率处理模块来鉴别幅度、包络大小、频率数值中的一种或多种,在通过调顶数据解码恢复模块输出恢复的数字调顶信号。The following describes the multi-mode top-receiving (RX) function of the system: As shown in Figure 8, in the top-receiving direction, the high-speed detector PD converts the optical signal into an electrical signal, and the high-speed data electrical signal is directly sent to the receiving driver chip. end. The slow top-adjusting signal is output from the photocurrent monitoring pin of the high-speed detector PD and sent to the top-adjusting analog signal extraction unit. In the extraction unit, the weak top-adjustment signal is amplified by the amplifier according to the top-adjustment mode, filtered and extracted, and then sent to the amplitude/frequency processing module of the second micro-control unit MCU2. According to the originally configured topping mode, the amplitude/frequency processing module identifies one or more of the amplitude, envelope size, and frequency value, and then outputs the restored digital topping signal through the topping data decoding and recovery module.
在进行调顶模拟信号的幅度、频率判决时,根据预先设定的调顶工作 模式,如果是纯调幅ASK模式,则仅仅根据模拟信号的幅度大小来判决,识别出数字1和0。由于只有幅度,无法识别出波长ID。When determining the amplitude and frequency of the analog signal, the preset operating mode is used. If it is a pure amplitude modulation ASK mode, the decision is made only based on the amplitude of the analog signal, and the numbers 1 and 0 are identified. Since there is only amplitude, the wavelength ID cannot be identified.
如果是多载频调幅ASK模式,则根据模拟信号的幅度大小判决后恢复原始调顶数据,同时识别载频的频率数值,根据频率与波长的对应关系,识别出当前接收到的光波长ID。例如,***Open-WDM规范中规定载频频率和波长的对应关系如图9所示,可参照图9中的对应关系得到与频率对应的波长。If it is a multi-carrier amplitude modulation ASK mode, the original modulation data is restored based on the amplitude of the analog signal, and the frequency value of the carrier frequency is identified. Based on the corresponding relationship between frequency and wavelength, the currently received optical wavelength ID is identified. For example, the China Mobile Open-WDM specification stipulates that the corresponding relationship between carrier frequency and wavelength is shown in Figure 9. You can refer to the corresponding relationship in Figure 9 to obtain the wavelength corresponding to the frequency.
如果是调频FSK模式,则根据预先定义的规则,根据识别出的频率数值来判决恢复出数值1和0,恢复原始的调试数据。例如:频率1KHz表示数字1,频率10KHz表示数字0。此外,还可以规定不同的波长采用不同的频率组合。例如:波长1267nm对应的频率组合是1KHz/10KHz,1KHz表示数字1,10KHz表示数字0。波长1274nm对应的频率组合是15KHz/24KHz,其中15KHz表示数字1,24KHz表示数字0。这样,在接收端,只要识别出频率是10KHz就对应波长1267nm,频率中有24KHz就对应波长1274nm。从而可以同时实现数据和波长ID的识别。If it is frequency modulation FSK mode, according to the predefined rules, the values 1 and 0 are restored according to the identified frequency value, and the original debugging data is restored. For example: a frequency of 1KHz represents the number 1, and a frequency of 10KHz represents the number 0. In addition, different frequency combinations can be specified for different wavelengths. For example: the frequency combination corresponding to the wavelength 1267nm is 1KHz/10KHz, 1KHz represents the number 1, and 10KHz represents the number 0. The frequency combination corresponding to the wavelength 1274nm is 15KHz/24KHz, where 15KHz represents the number 1 and 24KHz represents the number 0. In this way, at the receiving end, as long as the frequency is identified as 10KHz, it corresponds to the wavelength of 1267nm, and if there is 24KHz in the frequency, it corresponds to the wavelength of 1274nm. This enables identification of data and wavelength ID at the same time.
随着微控制单元MCU制造工艺的进步和集成度的提高,本实施例的另一实施方案中,第一微控制单元MCU1和第二微控制单元MCU2的功能可以合并在一个微控制单元MCU内部来完成,例如图10所示,其将原第一微控制单元MCU1与设备交互的I2C1接口以及TX/RX调顶数据存储1模块合并到原第二微控制单元MCU2中,如此一来可省去原第一微控制单元MCU1和第二微控制单元MCU2的内部数据接口,而直接通过TX/RX调顶数据存储1模块来和各功能模块相连。其他各功能模块的功能与原第二微控制单元MCU2功能一致,在此就不再赘述。With the advancement of the manufacturing process and the improvement of integration of the micro control unit MCU, in another implementation of this embodiment, the functions of the first micro control unit MCU1 and the second micro control unit MCU2 can be merged into one micro control unit MCU. To complete, for example, as shown in Figure 10, it merges the I2C1 interface of the original first micro-control unit MCU1 with the device and the TX/RX adjustment data storage 1 module into the original second micro-control unit MCU2, so that it can save The original internal data interfaces of the first micro control unit MCU1 and the second micro control unit MCU2 are removed, and directly connected to each functional module through the TX/RX top data storage 1 module. The functions of other functional modules are consistent with the functions of the original second micro-control unit MCU2, and will not be described again here.
综上所述,本实施例通过微控制单元可以完成与设备主CPU交互的功能,还能通过微控制单元内部各个模块的组合以及归一化的外部调顶硬件 电路实现纯调幅ASK、多载频调幅ASK、调频FSK三种调顶模式的功能。也即是说,本公开只需采用同一个PCBA(微控制单元设在PCBA上)就可支持纯调幅ASK、多载频调幅ASK、调频FSK三种调顶模式,通过软件配置对应的参数来进行工作模式的选择,从而仅需要一个产品型号就解决了多种调顶模式的选择,进而解决了远端光模块管理的问题,降低了生产成本和库存压力,不需要现场更换光模块就可以灵活地切换调顶方式,降低了运营和维护成本。另外,本公开的调顶速率可以根据客户需要,支持1kbps到几千Kbps的速率配置。To sum up, this embodiment can complete the function of interacting with the main CPU of the device through the micro control unit, and can also realize pure amplitude modulation ASK and multi-load through the combination of various modules inside the micro control unit and the normalized external top-adjusting hardware circuit.
