本发明描述促进两个设备之间的数据之传输的系统、方法及设备。一种数据发送方法包括：自一第一界面接收第一数据，该第一数据系在由一第一设备根据一第一协定传输之发信中接收；判定待用于将该第一数据传输至一第二设备之一通信链路之一操作模式；在一第一操作模式中经由该通信链路之一光学路径将该第一数据传输至该第二设备；在一第二操作模式中经由该通信链路之一电路径根据该第一协定将该第一数据传输至该第二设备；及在一第三操作模式中，转译该第一数据以获得第二数据且经由该电路径根据一第二协定将该第二数据传输至该第二设备。

System, methods and apparatus are described that facilitate transmission of data between two devices. A data transfer method includes receiving first data from a first interface, the first data being received in signaling transmitted by a first device according to a first protocol, determining a mode of operation for a communication link to be used for transmitting the first data to a second device, transmitting the first data to the second device over an optical path of the communication link in a first mode of operation, transmitting the first data in accordance with the first protocol to the second device over an electrical path of the communication link in a second mode of operation, and in a third mode of operation, translating the first data to obtain second data, and transmitting the second data in accordance with a second protocol to the second device over the electrical path.
