Patent number: 9509410Abstract: A high-speed 100G optical transceiver, such as for InfiniBand and Ethernet, with associated mapping to frame various different protocols. 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, re-framing, 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.Type: GrantFiled: January 20, 2016Date of Patent: November 29, 2016Assignee: Ciena CorporationInventors: John P. Mateosky, Michael Y.
