    • In order to increase the capacity of a deployed passive optical network (PON) without replacing optical network terminators (ONTs), a PON is provided that is partitioned into multiple channels. The upstream and downstream channels in the PON are partitioned into M channels, with the number of channels on the upstream preferably equaling the number of channels on the downstream. In the downstream, the partitioning is accomplished by use of wavelength division multiplexing filters arranged in a way as to place groups of ONTs on M different wavelength bands, where all of the wavelength bands are within the downstream wavelength range of the existing PON. On the upstream, partitioning is accomplished using "injection locking" to narrow the possible wavelength range of each ONT transmitter to a portion of that possible in the existing PON.
    • 为了增加部署的无源光网络(PON)的容量而不替换光网络终端器(ONT),提供了被划分成多个信道的PON。 PON中的上行和下行信道被划分为M个信道,上游的信道数量优选地等于下游的信道数。 在下游,通过使用波长分配复用滤波器来实现划分,波分复用滤波器以在不同波长带上放置ONT组的方式布置,其中所有波长带都在现有PON的下游波长范围内。 在上游,使用“注入锁定”来实现分区,以将每个ONT发射机的可能波长范围缩小到现有PON中可能的一部分。

    • Systems and methods increase the available bandwidth for stations on a network, eliminate collisions during normal operations, do not require a network administrator, scale essentially linearly, are self-organizing, self-diagnosing and reporting, and are deterministic. One station becomes the starting bus master and creates a table of all the stations on the network along with their corresponding delays relative to the starting bus master. The stations communicate in an order determined by the starting bus master with the first station being a starting bus master and the last station an ending bus master. The starting bus master transmits a beginning of sequence message and the ending bus master generates an end of sequence message. The stations need not be limited to any specific wavelength nor need they be forced to transmit during any specific time slot. The network automatically adds or drops stations from the network.
    • 系统和方法增加了网络上站点的可用带宽,消除了正常运行时的冲突,不需要网络管理员,基本线性地进行规模化,自我组织,自我诊断和报告,并且是确定性的。 一站成为起始总线主机,并创建网络上所有站的表以及相对于起始总线主站的相应延迟。 这些站以起始总线主站确定的顺序进行通信,第一站是起始总线主站,最后一站是结束总线主站。 起始总线主机发送序列消息的开始,结束总线主机产生序列消息的结束。 站不需要限制在任何特定的波长,也不需要在任何特定的时隙中被迫发送。 网络自动从网络添加或删除站点。
