摘要： A transmission line is provided with added shunt resistance, RSH, distributed along the length of the micro transmission line permitting the extension of constant characteristic impedance to the transmission line to lower signal frequencies. The loss in gain to the signal propagating the transmission line due to the added resistance can be compensated for by amplification provided at the output of the transmission line or at output taps provided along the length of the transmission line such as in cases where the line is utilized as a circuit delay line. An exemplified application disclosed is an analog delay line formed as a metal microstrip in an IC chip circuit provided, for example, in a feed forward equalizer (FFE).

摘要： An optical transmission network is inherently asynchronous due to the utilization of a variable overhead ratio (V-OHR). The network architecture makes extensive use of OEO regeneration, i.e., deals with any electronic reconditioning to correct for transmission impairments, such as, for example, FEC encoding, decoding and re-encoding, signal reshaping, retiming as well as signal regeneration. The optical transmission network includes a plesiochronous clocking system with intermediate nodes designed to operate asynchronously with a single local frequency clock without complicated network synchronization schemes employing high cost clocking devices such as phase locked loop (PLL) control with crystal oscillators and other expensive system components. The asynchronous network operation provides for asynchronous remapping or remapping of any client signal utilizing any type of transmission protocol where the line side rate or frequency is always the same frequency for the payload signal and the local frequency at an intermediate node is set to a local reference clock in accordance with the payload type and its overhead ratio, i.e., the overhead ratio is varied to meet the desired difference between the line rate or frequency and the desired client signal payload rate or frequency for the particular client signal payload type.
摘要翻译：由于使用可变开销比（V-OHR），光传输网络固有地是异步的。网络架构广泛使用OEO再生，即处理任何电子修复以校正传输损伤，例如FEC编码，解码和重新编码，信号整形，重新定时以及信号再生。光传输网络包括一个专用时钟系统，其中间节点设计成与单个本地频率时钟异步运行，而无需采用高成本时钟设备（如晶体振荡器和其他昂贵的系统组件的锁相环（PLL））控制）的复杂网络同步方案。异步网络操作提供使用任何类型的传输协议的任何客户端信号的异步重映射或重新映射，其中线路边速率或频率对于有效载荷信号总是相同的频率，并且中间节点处的本地频率被设置为本地参考根据有效载荷类型和其开销比，即，开销比被改变以满足线速率或频率与特定客户端信号有效载荷类型的期望的客户端信号有效载荷速率或频率之间的期望差。

摘要： A method is disclosed for monitoring and controlling the bit error rate (BER) in an optical communication network where an optical receiver in the optical transmission network is a monolithic photonic integrated circuit (RxPIC) chip. The method includes the steps of decombining on-chip a combined channel signal received from the network and then monitoring a real time bit error rate (BER) of a decombined channel signal. The determined BER is then communicated, such as through an optical service channel (OSC) to an optical transmitter source that is the source of origin of the channel signal. Based upon the determined BER, the chirp of a channel signal modulator at the optical transmitter source that generated the monitored channel signal is adjusted by, for example, adjusting its bias. The same channel signal received at the RxPIC chip can be monitored again to determine if an acceptable level for the BER has been achieved by the previous chirp adjustment.

摘要： A propagation delay in the transmission of a frame from an initiator node to a peer node is determined by initially identifying a frame number and byte offset of a first incoming frame from the peer node at a time when the initiator node outputs a portion of a transmitted frame. The portion of the transmitted frame may be the first byte of a sub-frame within the transmitted frame. At the peer node, the frame number and byte offset of a second frame to be supplied to the initiator node is identified at a later time when the frame portion transmitted by the initiator node is received by the peer node, and such information is transmitted to the initiator node. Thus, since the frames output and received by the initiator node are typically of fixed duration, the frame number and byte offset of the incoming frame represent the time when the initiator node outputs the frame portion (a transmit time). In addition, the frame number and byte offset of the second frame represents the time at which the frame portion is received by the peer node (a receive time). Accordingly, by comparing the frame numbers and byte offsets of the first and second frames received from the peer node, a difference between transmit and receive times or propagation delay can be obtained.
摘要翻译：通过在发起者节点输出发送的一部分的时间，首先识别来自对等节点的第一输入帧的帧号和字节偏移来确定帧从发起者节点传输到对等节点的传播延迟帧。发送帧的部分可以是发送帧内的子帧的第一个字节。在对等节点，由发起方节点发送的帧部分由对端节点接收到的时候，识别要提供给发起方节点的第二帧的帧号和字节偏移，并将这些信息发送到启动器节点。因此，由于由发起者节点输出和接收的帧通常是固定持续时间，所以入局帧的帧号和字节偏移表示发起者节点输出帧部分的时间（发送时间）。此外，第二帧的帧号和字节偏移表示对等节点接收帧部分的时间（接收时间）。因此，通过比较从对等节点接收到的第一和第二帧的帧号和字节偏移，可以获得发射和接收时间之间的差异或传播延迟。

摘要： An optical receiver photonic integrated circuit (RxFIC) comprises a semiconductor monolithic chip having an input to receive from an optical transmissior link a combined channel signal originating from an optical transmitter source and comprising a plurality of channel signals having different wavelengths forming a wavelength grid. An optical decorobiner is integrated in the chip and optically coupled to the input to receive the multiplexed channel signal and provide a decombined individual channel signal on an output waveguide of a plurality of such output waveguides provided from the optical decombiner. A plurality of photodetectors are also integrated in the chip and each photodetector is optically coupled to one of the output waveguides to receive a decombined channel signal and convert the channel signal to an electrical signal. A controller is coupled to receive a portion of the converted signals to determine at least one performance property of the signals and provide service channel signal as feedback about that property via the semiconductor monolithic chip to the optical transmitter source. The controller is coupled to an integrated optical service channel (OSC) on the chip that has a light source which is modulated by the service channel signal. The light source may he integrated on the chip. The optical service channel (OSC) is coupled as an input to the decombiner for transport off the chip to optical transmitter source.
