(上接第7期)光链路传输部分是指光工作站回传输入端口至前端回传光接收机输出端口,这部分设计的核心问题是采取合理的措施,以保证加到回传激光器上的RF信号总功率在一个合适的范围之内,即不可太小又不能过大,这样即使某种原因使激励功率增大或减小,激光器
(Continued on the 7th) Optical link transmission part refers to the optical workstation return input port to the front-end return optical receiver output port, this part of the design of the core issue is to take reasonable measures to ensure that added to the backhaul laser Of the total RF signal power within a suitable range, that is not too small nor too large, so even if for some reason the excitation power increases or decreases, the laser
