在光通信技术领域中,光模块(Optical Transceiver Module,TRX)主要用于实现光电的转换功能,其中,光模块向外部光纤中输入的光信号强度会影响光纤通信的质量。
此外,由于无源光纤网络(Passive Optical Network,PON)具有高带宽、高效率、覆盖范围大等优点,因此PON是现在宽带接入网的主流技术方案。
现有的基于PON的光接入系统,包括1G-PON和10G-PON,下一代基于PON的光接入系统将从10G速率向50G速率演进。但是,由于未来50G-PON在建设部署的过程中,是基于现网的1G-PON和10G-PON系统共存演进的,所以50G-PON与1G-PON和10G-PON将在未来一段时间内共存。
由于在1G-PON或10G-PON不同端口下,光纤距离、光网络单元(Optical Network Unit,ONU)、分光比、光纤质量等各不相同,每个PON端口的链路光功率预算指标也不同。因此,在1G-PON、10G-PON与50G-PON共存的场景下,需要对50G-PON的每个端口基于1G-PON或10G-PON每个端口的具体光功率预算情况进行调节。
示例性的,在对50G-PON的每个端口进行光功率调节时,传统的板载光

下面对本申请实施例的设计思想进行简要介绍:
在光通信技术领域,TRX主要用于实现光电的转换功能,其中,光模块向外部光纤中输入的光信号强度会影响光纤通信的质量。
此外,由于PON具有高带宽、高效率、覆盖范围大等优点,因此PON是现在宽带接入网的主流技术方案。
现有的基于PON的光接入系统,包括1G-PON和10G-PON,下一代基于PON的光接入系统将从10G速率向50G速率演进。但是,由于未来50G-PON在建设部署的过程中,是基于现网的1G-PON和10G-PON系统共存演进的,所以50G-PON与1G-PON和10G-PON将在未来一段时间内共存。
由于在1G-PON或10G-PON不同端口下,光纤距离、ONU、分光比、光纤质量等各不相同,每个PON端口的链路光功率预算指标也不同。因此,在1G-PON、10G-PON与50G-PON共存的场景下,需要对50G-PON的每个端口基于1G-PON或10G-PON每个端口的具体光功率预算情况进行调节。
示例性的,在对50G-PON的每个端口进行光功率调节时,传统的板载光源池采用无源的光功率分光器,将一路光源分为多路光信号,进行后续光信号调制后,向每个下行的光发送端口进行传输。
由此可见,采用上述方式无法灵活调制每一路光信号的光功率,可能会
造成某些PON端口的光功率过高或过低,从而导致某些PON端口下挂的ONU业务无法正常进行。
有鉴于此,为了实现对不同PON端口的光功率调节,本申请实施例中提出了一种光发射装置及光发射方法。
参阅图1所示,为本申请实施例提供的一种光发射装置的应用场景示意图。在图1中,光发射装置可以包括多个PON端口,其中,每个PON端口可以下挂一个ONU或者每个PON端口可以下挂多个ONU。每个PON端口可以向ONU提供光信号。在本申请实施例中,PON端口指局端设备(Optical Line Terminal,OLT)面向ONU的光接口。
参阅图2所示,为本申请实施例提供的光发射装置的结构示意图。光发射装置100可以包括板载光源池10、光功率分配模块11、光功率检测模块12、控制模块13、光衰减模块14以及光调制发射模块15。其中,光功率检测模块12可以包括多个光功率检测子模块、光衰减模块14可以包括多个光功率检测子模块。在本申请实施例中,光功率检测模块12、光衰减模块14以及光调制发射模块15对光信号的处理,形成一个下行光通道。
板载光源池10与光功率分配模块11连接,板载光源池10具有输出光的能力或功能。板载光源池10作为本申请实施例中的光源用于向光功率分配模块11提供初始光信号。光功率分配模块11可以连接多个光通道,光功率分配模块11在接收到板载光源池10发射的初始光信号时,能够对板载光源池10发射的初始光信号进行功率分配,并将板载光源池10发射的初始光信号分为多路光信号,得到N个PON端口各自对应的一路光信号。在本申请实施例中,N为大于等于2的正整数。比如说,PON端口的数量为3个,光功率分配模块可以将板载光源池发射的初始光信号进行光功率分配后分为3路,每一路光信号的光功率为初始光信号的光功率的三分之一。
板载光源池10向光功率分配模块11发射初始光信号后,可以按照各个PON端口的光功率的情况以及各个PON端口的光功率阈值对初始光信号的光功率进行调节,从而使各个PON端口对应的光功率更接近各自的光功率阈值。
举例来讲,若假定PON端口1的光功率阈值(即目标光功率值)为50毫瓦,PON端口2的光功率阈值为40毫瓦,而板载光源池10发射的初始光信号的光功率为90毫瓦,则将板载光源池10发射的初始光信号分为两路后,PON端口1和PON端口2各自对应的一路光信号的光功率为45毫瓦。因此,为了满足PON端口1对应的一路光信号对光功率的需求,可以将板载光源池10发射的初始光信号的总光功率进行调整。比如,将板载光源池10发射的初始光信号的光功率调整为100毫瓦,则由光功率分配模块11进行初始光信号分路以及光功率分配后,PON端口1和PON端口2各自对应一路的光信号的光功率为50毫瓦,能够同时满足PON端口1和PON端口2对光信号的光功率要求。
在一种可选的实施方式中,板载光源池10可以包括多种发射波长的光源。
例如,1G-PON系统采用的1260nm-1360nm或者1480nm-1500nm波长的光源,10G-PON系统采用的1260nm-1280nm或者1575nm-1679nm波长的光源,50G-PON系统采用的1260nm-1280nm或者1284nm-1288nm波长的光源,或者其他发射波长的光源,本申请实施例在此不做具体的限定。
在板载光源池10中采设置不同发射波长的光源,从而可以满足不同的传输速率。避免了相关技术中采用可插拔光模块时,一种可插拔光模块只能提供一种发射波长的光源的局限。
进一步来讲,光功率检测模块12与光功率分配模块11连接,光功率检测模块12用于检测由光功率分配模块11进行分路和光功率分配后输出的N路光信号各自的当前功率值,从而可以确定每一路光信号的光功率情况。
在一种可选的实施方式中,如图2所示,光功率检测模块12可以包括多个光功率检测子模块,每个光功率检测子模块用于检测相应的一个PON端口对应的当前光功率值。可选地,光功率检测子模块的数量根据PON端口的数量对应设置,本申请实施例在此不作具体的限定。
控制模块13与每一个光功率检测子模块连接,控制模块13能够获取各光功率检测子模块检测到的N路光信号各自对应的当前光功率值,以及对应
N路光信号分别设置的光功率阈值,从而计算得到N路光信号各自对应的目标衰减值。
在一种可选的实施方式中,控制模块13还可以与管理系统连接,管理系统用于分别获取N路光信号中的每一路光信号的光功率阈值。具体地,管理系统根据每一个PON端口所连接的ONU数量、光纤传输距离等参数,确定每一PON端口对应的一路光信号的光功率阈值。当某个PON端口下挂的ONU数量较多、光纤传输距离较远时,则该PON端口对应的光功率阈值较大。因此,板载光源池10输出的初始光信号的总功率调大,即可将该PON端口对应的光功率阈值调大。在本申请实施例中,管理系统为运营商对光通信网络进行管理的系统,管理系统可以根据实际应用场景获取每一路光信号对应的光功率阈值。
进一步,当光功率检测子模块检测到每一路光信号的当前光功率值,以及控制模块13根据管理系统获取到每一路光信号的光功率阈值时,控制模块13可以计算出每一路光信号各自对应的目标衰减值。举例来讲,某一路光信号的当前光功率值为50毫瓦,以及光功率阈值为40毫瓦,则目标衰减值为10毫瓦。
在一种可选的实施方式中,如图2所示,光衰减模块14可以包括N个光衰减子模块。在本申请实施例中,每个光衰减子模块用于对相应的一个PON端口的当前光功率值进行衰减,直到一个PON端口的光功率值达到一个PON端口对应的光功率阈值为止。
在一种可选的实施方式中,控制模块13基于管理系统获取到的N路光信号中的每一路光信号的光功率阈值,以及基于光功率检测模块12检测到的每一路光信号的当前光功率值时,计算得到N路光信号各自对应的目标衰减值,进一步,控制模块13向N个PON端口各自对应的光衰减子模块下发N个PON端口各自对应的目标衰减值。
光衰减子模块在接收到控制模块13计算得到的N路光信号各自对应的目标衰减值后,分别对N个PON端口的当前功率值进行衰减,直到N个PON
端口的光功率值达到各自对应的光功率阈值为止。由于各个PON端口对光功率的需求不同,所以各个PON端口各自对应的目标衰减值也不同,每个光衰减子模块对相应的一个PON端口的当前光功率值进行衰减后,从而满足各个PON端口各自对光功率的需求。
比如说,PON端口1对应的光功率阈值为50毫瓦,以及PON端口1的当前光功率值为60毫瓦,则PON端口1对应的光衰减子模块1根据目标衰减值10毫瓦对PON端口1的当前光功率值进行衰减,直到PON端口1的光功率值达到对应的光功率阈值。同理,光衰减子模块2对应PON端口2,光衰减子模块N对应PON端口N,在本申请实施例中各光衰减子模块的作用相同,用于根据目标衰减值对各PON端口的当前功率值进行衰减,直到各PON端口的光功率值达到各自对应的光功率阈值为止。
在一种可选的实施方式中,如图2所示,本申请实施例提供的光发射装置还包括N个光调制发射模块15。光调制发射模块15具有光调制能力以及光发射能力,光调制发射模块15可以对光信号的参数进行调制,以得到对应的调制光信号。具体来讲,光调制发射模块15对经由光衰减模块14进行光衰减后的一路光信号,对光信号的振幅、相位、强度、偏振态等参数进行调制,并将相应的业务信息加载在光信号后输出至对应的PON端口。
在光发射装置100中,控制模块可以获取每个PON端口的当前光功率值和每个PON端口的光功率阈值,从而根据每个PON端口的当前光功率值和每个PON端口的光功率阈值得到每个PON端口的目标衰减值。进一步,由各光衰减子模块根据各PON端口的目标衰减值,对光信号进行衰减,直到各PON端口的当前功率值满足各自的光功率阈值,从而实现对各PON端口的光功率的灵活调整,提高了无源光纤网络的可靠性和灵活性。避免了相关技术中,有光功率分配模块对初始光信号进行分路后,各PON端口获得的光功率相同且无法单独调节的问题。
基于同一发明构思,本申请实施例中还提供了一种光发射方法,应用于前述任意一个实施例提供的光发射装置。参阅图3所示,该方法可以包括:
S301:接收板载光源池发射的初始光信号,并对初始光信号进行分路,得到N个PON端口各自对应的一路光信号。
S302:检测光功率分配模块输出的N路光信号各自的当前光功率值。
S303:基于光功率检测模块检测到的N路光信号各自对应的当前光功率值,以及对应N路光信号分别设置的光功率阈值,计算N路光信号各自对应的目标衰减值。
S304:基于控制模块计算得到的N路光信号各自对应的目标衰减值,分别对N个PON端口的当前光功率值进行衰减,直到N个PON端口的光功率值达到各自对应的光功率阈值为止。
通过上述的方法,实现了对无源光纤网络中各个光通道的光功率调节,能够使各个光通道的光功率满足各自的需求,提高了无源光纤网络的灵活性以及可靠性。
