具体实施方式
本发明实施例提供一种光通信节能方法和装置, 实现了在光模块 正常工作的情况下, 降低了光通信设备的功耗, 提高了通讯效率。
下面结合附图对本发明实施例做详细描述。
实施例一
本实施例提供一种光通信节能方法, 应用于光通信系统, 该系统 包括本端光通信设备以及对端光通信设备, 每个光通信设备内部都包括 光模块以及处理器, 光模块用于进行光信号的收发操作, 两端设备的光 模块通过光纤进行相连, 处理器用于对光模块收发的信号进行处理。 如 图 1所示, 本实施例从本端光通信设备的角度来描述节能方法, 如无特 别说明, 下面方法步骤中前面没带 "本端" 、 "对端" 修饰词的 "处理 器" 、 "光模块" 等均指 "本端光通信设备中的处理器" 和 "本端光通 信设备中的光模块" , 所述光模块的光发射功率称为所述光通信设备 的发射光功率. 具体的, 该光通信节能方法包括:
步骤 101、将所述光通信设备的发射光功率取第一发射光功率值通 过光纤向对端光通信设备发送第一信息。
本实施例的光通信设备包括处理器以及光模块, 处理器与光模块 相连, 具体的, 处理器可通过 I2C总线与光模块相连接。 这里光通信设 备的发射光功率也为光模块的发射光功率,如果实际当中光通信设备采 用与光模块类似的硬件光发射器件,则这个发射光功率也可以为类似进 行光发射器件的发射光功率。光通信设备中的光模块通过光纤与对端光 通信设备相连以进行光通信。 由于在长距离的传输中, 光通信设备发出 的光信号在光纤中会衰减, 因此, 光通信设备以第一发射光功率取第一 发射光功率值 Pas发出的第一信息,在到达作为目的光通信设备的对端 光通信设备时, 其光功率值会有所减小。 本实施例中, 称第一信息到达 对端光通信设备时的光功率为 "接收光功率" , 记该接收光功率值为 PBr, 故光通信设备和对端光通信设备之间的光信号功率值衰减为:
PAs-PBr„
步骤 102、接收所述对端光通信设备收到所述第一信息后返回的第 二信息,所述第二信息包括所述对端光通信设备接收所述第一信息时的 接收光功率值以及所述对端光通信设备可识别的最小接收光功率值。
接收灵敏度是指设备可识别的最小接收光功率值。 每个光通信设 备都有其发射和接收光功率的极限值,记对端光通信设备最大接收光功 率为 PBr— H, 接收灵敏度(最小接收光功率 )为 PBr— L, 当接收到的信 号的功率值大于 PBr— H或者小于 PBr— L时, 对端光通信设备便不能正 常接收该信号, 因此,对端光通信设备接收到的来自光通信设备的第一 信息的功率值应满足:
PBr— H>PBr>PBr_L。
对端光通信设备在接收到来自光通信设备的第一信息后, 读取存 储在对端光通信设备中的参数值, 其中, 参数值包括对端光通信设备的 接收灵敏度 PBr— L, 然后向光通信设备发送携带有接收光功率值 PBr 以及接收灵敏度 PBr— L等信息的第二信息。
光通信设备接收来自对端光通信设备的第二信息。
步骤 103、根据第一发射光功率以及接收到的第二信息中的接收光 功率值、 最小接收光功率值, 将光通信设备的发射光功率值调整为第一 发射光功率值与接收光功率值的差值加上对端光通信设备的最小接收 光功率值和余量值。
根据第一信息在光通信设备的第一发射光功率值和到达对端光通 信设备时的接收光功率值, 处理器可计算出发送的信号在光纤中的衰减 为 PAs-PBr, 由于对端光通信设备的最小接收光功率为 PBr— L, 因此, 光通信设备发送的第一信息的功率值到达对端光通信设备时不能小于 PBr— L, 故第一信息的发射光功率值 Pas至少为:
( PAs-PBr ) +PBr_L。
考虑到设备、 环境等因素会给计算带来一定的误差, 以及光模块 在运行一定时间后其发射光功率会出现衰减, 为保证光通信设备的可靠 性, 需要给目的光通信设备保留一定的余量值 Δ Ρ , 故第一信息的发射 光功率值 Pas可调整为:
( PAs-PBr ) +PBr_L+ Δ Ρ , 其中, Δ Ρ的取值大小可根据实际情况 (如误差、 可靠性等方面的考虑) 合理的选取, 一般取一个大于等于 0 的数。
处理器在计算出合适的发射光功率后, 通过 I2C 总线向光模块发 出控制指令, 修改光模块存储在内存中的参数, 以降低发射光功率。 发 射光功率降低后, 光通信设备的功率也相应的降低。
光通信设备在调整发射光功率后, 还要检查调整后的发射光功率 值是否在正常范围内, 即光通信设备降低后的发射光功率值不大于光通 信设备的最大发射光功率值 PAs— Η,且不小于光通信设备的最小发射光 功率值 PAs— L。 如果不在正常范围内, 则需要对发射光功率值作进一步 调整,使之在正常范围之内。例如,若( PAs-PBr )+PBr_L的值小于 PAs— L , 则调整后的发射光功率至少为 PAs— L。
通过上述步骤, 光通信设备就可以降低发射光功率, 从而减少了 功耗。
进一步的, 本实施例还可在光通信设备发送的第一信息中携带光 通信设备的接收灵敏度 PAr— L和发射光功率值 PAs的信息, 对端光通 信设备在接收到第一信息后, 再根据第一信息到达对端光通信设备时的 功率值 PBr, 调整对端光通信设备的发射光功率值, 调整后的发射光功 率值至少为:
( PAs-PBr ) +PAr_L。
考虑到设备、 环境等因素会给计算带来一定的误差, 因此需要给 目的光通信设备保留一定的余量值 Δ Ρ , 故对端光通信设备的发射光功 率可调整为:
( PAs-PBr ) +PAr_L+ Δ Ρ , 其中, Δ Ρ的取值大小可根据实际情况 合理的选取。
可见, 通过上述简单的信号交互, 可同时完成光通信设备和对端 光通信设备的发射光功率值的调整, 从而降低了光通信设备的功耗, 提 高了通讯效率。
进一步的, 由于光模块在运行一定时间后其发射光功率会出现衰 减, 光纤也会因长时间的使用发生老化导致衰减加剧, 因此, 为保证数 据的准确性, 以及防止因突发事件给光通信设备带来不利的影响, 本实 施例还定时检测光通信设备的发射光功率值和接收光功率值是否在正 常范围内, 在正常范围内是指发射光功率值在最大发射光功率值与最小 发射光功率之间, 接收光功率值在最大接收光功率值与最小接收光功率 之间;
若检测光通信设备的发射光功率值和接收光功率值不在正常范围 内, 则需重新发送第一信息至对端光通信设备, 并重复上述步骤, 以调 整发射光功率值。 同理, 对端光通信设备也可定时检测其发射光功率值 和接收光功率值是否在正常范围内。
本实施例的光通信节能方法, 通过向对端光通信设备发送具有发 射光功率值的第一信息, 然后接收来自对端光通信设备的携带有接收光 功率值以及所述对端光通信设备的最小接收光功率值的信息的第二信 息, 并根据接收光功率值、 对端光通信设备的最小接收光功率值, 降低 发射光功率值, 实现了在光模块正常工作的情况下, 降低了光通信设备 的功耗, 此外, 还可在光通信设备发送的第一信息中携带光通信设备的 最小接收光功率值和发射光功率值的信息, 对端光通信设备在接收到第 一信息后, 再根据第一信息到达对端光通信设备时的功率值, 调整对端 光通信设备的发射光功率值, 通过上述简单的信号交互, 可同时完成光 通信设备和对端光通信设备的发射光功率值的调整, 从而降低了光通信 设备的功耗, 提高了通讯效率。
