摘要
针对城域网中终端用户的随机性地理分布,造成不同用户距光通信设备的距离相差悬殊,导致彼此光纤传输链路长度相差较多。为此,以光端机的接收和发送光功率为探讨对象,结合工程建设实际,阐述了不同长度光纤链路衰减与放大的解决方案。
Because every terminals distribute randomly in a metro network,the distances between different terminal users and optical communications equipment are very discrepant.We take the transmitting and receiving power of the optical communications equipment as the main discussion object and combine with practical project construction,the solution to the attenuation and amplification in optical fiber links with different distances are described.
