摘要
为解决通用串行总线(USB)信号的传输距离受限问题,提出了一种用光纤来代替电缆传输的USB信号延长方案。该方案将USB信号转换为千兆以太网光信号来实现信号的远距离传输。同时在用户端电路加入USB接口扩展设计,将单路用户接口扩展为多路,可满足多个USB设备同时接入的要求。
In order to solve the problem that the transmission distance of universal serial bus（USB） signal is limited, the USB signal transmission scheme in which the optical fiber transmission takes the place of the cable transmission is proposed. The USB signal is transformed to gigabit ethernet optical signal to achieve long distance transmission of the signal in the scheme. At the same time, the USB interface expansion design is added to the client circuit and the single user interface is extended to multiple, the requirements that multiple USB devices insert at the same time can be satisfied.
