Description

一种数据传输的方法及装置 技术领域
本公开涉及通信技术领域，特别涉及一种数据传输的方法及装置。
背景技术
光纤通信已经成为现代信息网络的主要传输手段之一，光收发一体模块是光纤通信系统中重要的器件。光收发一体模块包括一体化设置在同一模块中的光器件单元，激光器驱动电路单元和光信号接收电路单元及其它控制单元部分。激光器驱动电路单元包括光功率控制电路、偏置电流监控电路、偏置驱动电路、背光控制电路及光调制驱动电路等部分。激光器的光驱动电流由调制电流与偏置电流组成，并同时受控于关断控制信号实现快速的开启或关断。
传统的小型可插拔(SMALL FORM PLUGGABLE，简称SFP)光模块(下文统称SFP光模块)的使用场景中，单板主控中央处理器(CentralProcessingUnit，简称CPU)通过IIC总线访问外围设备SFP光模块，通过SFP光模块硬件内部光收发一体组件(Bi-Directional Optical Sub-Assembly，简称BOSA)驱动芯片、微控制单元(Microcontroller Unit，简称MCU)和电可擦可编程只读存储器(Electrically Erasable Programmable Read-Only Memory，简称EEPROM)结合的方式实现工业标准多边协议—SFF-8472协议，提供数字诊断光模块—DDMI的数字诊断等功能。
目前，各种网络中所需要的光收发一体模块种类越来越多，要求也越来越高。为了满足系统不断增长的需求，光传输模块正不断走向标准化、小型化、智能化发展。其中，基于BOB技术的光收发一体组件在板(BOSA-On-Board，简称BOB)光模块(以下简称BOB光模块)的使用越来越多。

需要说明的，步骤S201是可替换的，即步骤S201可以理解为对图1所示的实施例中的步骤S101的限定，但在本公开实施例中，步骤S101并不限定为步骤S201的实施方式，还可以获取所述BOB光模块中其他可以提供配置数据的零件或部件中的配置数据来使用。

构建完成所述第一数据表和所述第二数据表后，即可按照所述SFF-8472协议进行数据的传输、检测等，下面以BOB光模块的DDMI数字诊断功能为例进行说明：
在构建所述SFF-8472协议及所述SFF-8472协议的数据表完成并初始化所述SFF-8472协议及所述SFF-8472协议的数据表后，所述驱动程序控制启动所述BOB光模块的CPU的内核线程，所述内核线程每100ms运行一次。
启动的所述内核线程首先读取所述激光器驱动芯片内部温度寄存器值，然后按照校准算法转换为所述SFF-8472协议格式值，并更新到所述第二数据表中。最后根据温度告警门限更新当前温度告警标识到所述第二数据表。
接着，启动的所述内核线程接着读取所述激光器驱动芯片内部调制电压寄存器值，然后按照校准算法转换为所述SFF-8472协议格式值，并更新到所述第二数据表中。最后根据调制电压告警门限更新当前调制电压告警标识到所述第二数据表。
接着，启动的所述内核线程接着读取所述激光器驱动芯片内部偏置电流寄存器值，然后按照校准算法转换为所述SFF-8472协议格式值，并更新到所述第二数据表中。最后根据偏置电流告警门限更新当前偏置电流告警标识到所述第二数据表。
接着，启动的所述内核线程接着读取所述激光器驱动芯片内部发送功率寄存器值，然后按照校准算法转换为所述SFF-8472协议格式值，并更新到所述第二数据表中。最后根据发送功率告警门限更新当前发送功率告警标识到所述第二数据表。
接着，启动的所述内核线程接着读取所述激光器驱动芯片内部接收功率寄存器值，然后按照校准算法转换为所述SFF-8472协议格式值，并更新到所述第二数据表中。最后根据接收功率告警门限更新当前接收功率告警标识到所述第二数据表。
接着，驱动程序读取单板BOB光模块的GPIO端口的电源控制管脚值，更新所述第二数据表中对应的发送电源控制状态位，并对所述BOB光模块的激光器的发送电源进行开启或关闭。
接着，驱动程序读取单板BOB光模块的GPIO端口的发送错误状态指示管脚值，更新所述第二数据表中对应的发送错误状态位。
然后，所述内核线程睡眠100ms，再一次重复上述各个数据监测的动作。
上述是以所述BOB光模块的DDMI数字诊断功能为例，进行说明所述BOB光模块实现所述SFF-8472协议，但并不局限于此。
