摘要： A fiber optic system includes a transmitter configured to utilize a plurality of modulation formats and a receiver communicatively coupled to the transmitter and configured to utilize a plurality of modulation formats. The transmitter and the receiver are cooperatively configured to set a modulation format of the plurality of modulation formats based upon optical signal-to-noise ratio associated therewith. A flexible bandwidth adaptation method includes monitoring at least one aspect of an optical link at a network element, responsive to the at least one aspect, computing a new modulation scheme for the optical link, and, if a solution is found for the new modulation scheme, changing to the new modulation format.

摘要： The present invention provides a serializer/deserializer (SERDES) circuit that can cover both client- and network-side interfaces for high-speed data rates. The present invention leverages commonality between the client and network (also known as line) side, and accommodates differences in a flexible manner. In one exemplary embodiment, the present invention provides a four-channel implementation to meet the requirement of both interfaces. The SERDES circuit can be capable of supporting both 40 Gb/s and 56 Gb/s data rates, can include an integrated DQPSK pre-coder and I/Q input/output signals, and can support RZ clock recovery. Additionally, the SERDES circuit can include differential coding support, electronic pre-emphasis, receiver-side electronic dispersion compensation, and the like.

摘要： The present invention provides a high-speed 100 G optical transceiver for InfiniBand and Ethernet with associated mapping to frame InfiniBand and Ethernet into GFP-T. The optical transceiver utilizes an architecture which relies on standards-compliant (i.e., multi-sourced) physical client interfaces. These client interfaces are back-ended with flexible, programmable Field Programmable Gate Array (FPGA) modules to accomplish either InfiniBand or Ethernet protocol control, processing, reframing, and the like. Next, signals are encoded with Forward Error Correction (FEC) and can include additional Optical Transport Unit (OTU) compliant framing structures. The resulting data is processed appropriately for the subsequent optical re-transmission, such as, for example, with differential encoding, Gray encoding, I/Q Quadrature encoding, and the like. The data is sent to an optical transmitter block and modulated onto an optical carrier. Also, the same process proceeds in reverse on the receive side.
摘要翻译：本发明提供了用于InfiniBand和以太网的高速100G光收发器，具有将InfiniBand和以太网格式化成GFP-T的相关映射。光收发器利用依赖于符合标准（即多源）物理客户端接口的架构。这些客户端接口具有灵活的可编程现场可编程门阵列（FPGA）模块，可实现InfiniBand或以太网协议控制，处理，重构等功能。接下来，信号用前向纠错（FEC）进行编码，并且可以包括额外的光传输单元（OTU）兼容框架结构。对于随后的光学重传，例如用差分编码，格雷编码，I / Q正交编码等适当地处理所得到的数据。将数据发送到光发射机模块并调制到光载波上。而且，相同的处理在接收侧进行相反的处理。
