    • Devices, systems and methods for run-time reassignment of the interconnection between devices pertaining to a Physical (PHY) layer and devices pertaining to a Media Access Control (MAC) layer. The PHY devices are typically located on I/O blades, while MAC devices are typically located on forwarding and control blades. A reconfigurable crossbar device interconnects I/O blades, forwarding blades and control blades. The network of PHY and MAC devices may use a standardized interfacing protocol configured to decouple physically a PHY and a MAC device. Remapping between a PHY and a MAC device is controlled by system management functions. A 'Remote Fault' or a 'Pause' message is used in combination with empty-traffic indicating 'idle patterns' in a system configured to accommodate the remapping of I/O blades to different Application-Specific Standard Product (ASSP) blades so as to avoid or eliminate, respectively, the loss of packets during hardware or software upgrades. During reassignment, traffic is buffered in the MAC device, to which the PHY device is to be switched.
    • 用于运行时重新分配与物理(PHY)层相关的设备与属于媒体访问控制(MAC)层的设备之间的互连的设备,系统和方法。 PHY设备通常位于I / O刀片上,而MAC设备通常位于转发和控制刀片上。 可重构的交叉开关设备将I / O刀片,转发刀片和控制刀片互连。 PHY和MAC设备的网络可以使用被配置为物理地去耦PHY和MAC设备的标准接口协议。 PHY和MAC设备之间的重映射由系统管理功能控制。 “远程故障”或“暂停”消息与配置为适应I / O刀片重新映射到不同应用专用标准产品(ASSP)刀片的系统中的空闲流量结合使用,指示“空闲模式”,以便 分别在硬件或软件升级期间避免或消除数据包的丢失。 在重新分配期间,业务被缓冲在MAC设备中,PHY设备将被切换到该设备。

    • An optical adapter includes an optical coupler, a plurality of fiber optic cables and an optical wavelength conversion device. The optical coupler is operable to receive a plurality of multi-mode single-wavelength optical signals having the same frequency. The plurality of fiber optic cables are arranged in parallel and each have a first end connected to the optical coupler and the other end is coupled to the optical wavelength conversion device. The optical wavelength conversion device is operable to optically convert between the plurality of multi-mode single-wavelength optical signals at the same frequency and a plurality of single-mode optical signals at different frequencies and multiplex the plurality of single-mode optical signals at the different frequencies onto a single-mode multi-wavelength optical waveguide. A corresponding optical adapter is provided for the receive side.
    • 光学适配器包括光耦合器,多个光纤电缆和光学波长转换装置。 光耦合器可操作以接收具有相同频率的多个多模单波长光信号。 多根光纤电缆平行布置,并且每根电缆具有连接到光耦合器的第一端和耦合到光波长转换装置的另一端。 光学波长转换装置可操作以在相同频率处的多个多模单波长光信号和处于不同频率的多个单模光信号之间进行光学转换,并且将多个单模光信号在 不同的频率到单模多波长光波导上。 为接收侧提供相应的光学适配器。
