摘要： An IDLE insertion technique maps MPCP time onto an EPoC PHY. The techniques address the variability of bandwidth due to bit loading over time. The techniques allow MPCP time to follow wall time at the MAC layer while tracking bytes at the PMD layer. The techniques also facilitate use of the EPON MAC with few changes in an EPoC environment. The bandwidth allocation messages may follow the same format as in EPON, and the techniques may implement IDLE insertion that accounts for EPoC PHY FEC overhead and datarate differences compared to the MAC.
摘要翻译： IDLE插入技术将MPCP时间映射到EPoC PHY上。该技术解决了随着时间的推移，由于位加载带宽的变化。这些技术允许MPCP时间跟踪MAC层的墙壁时间，同时跟踪PMD层的字节。这些技术还有助于在EPoC环境中几乎没有变化的EPON MAC的使用。带宽分配消息可以遵循与EPON相同的格式，并且该技术可以实现与MAC相比的考虑到EPoC PHY FEC开销和数据差异的IDLE插入。

摘要： A system, method and apparatus for power saving using burst-mode transmission over point-to-point physical connections. In one embodiment, a physical layer device (PHY) is provided that includes a data detector that is configured to generate a first control signal upon receipt of a non-idle code group over an interface between the PHY and a media access control (MAC) device and to generate a second control signal when all data received from the MAC device has been transmitted by the physical layer device. The PHY also includes a laser for transmission of data over an optical network cable, the laser being configured to perform a first transition from an off state to an on state based on the first control signal, and to perform a second transition from the on state back to the off state based on the second control signal.

摘要： In general, the 1G-EPON standard specifies its upstream waveband broadly to allow for low cost lasers to be used to transmit upstream. Often, however, the lasers actually used by many 1G-ONUs to transmit upstream only occupy a narrow waveband that does not overlap with the upstream waveband specified by the 10G-EPON standard. The present disclosure is directed to systems and methods that exploit this fact to efficiently provide for the coexistence of 10G-EPON and 1G-EPON over the same set of optical fibers in the upstream direction.
摘要翻译：一般来说，1G-EPON标准规定了其上游波段，以允许低成本激光器用于向上游传输。然而，通常，许多1G-ONU实际上用于上行传输的激光器仅占用与10G-EPON标准规定的上行波段不重叠的窄波段。本公开涉及利用该事实有效地提供10G-EPON和1G-EPON在上游方向上在同一组光纤上共存的系统和方法。

摘要： A system and method for reduced latency reporting in an Ethernet passive optical network (EPON). Gate messages can be generated by a bridged fiber coax unit (FCU) in response to a first report message from a coax network unit (CNU). A second report message including a request for bandwidth can be transmitted to the optical line terminal (OLT) prior to receipt of upstream data at the FCU.
