应用1550nm光传输技术加快广电农网双改建设

Apply 1,550 nm Optical Transmission,Accelerate Construction of Rural Network Double Changes

1 550 nm光传输技术已成为广电网络传输的主流技术,用1 550 nm光传输系统组网有结构简单、应用方便、可靠性高、投资少等特点,是目前广电双网双改较理想的传输方案。根据1 550 nm光传输技术C/N指标的计算,前端和分前端以及光节点的实用组网方式,并结合EPON、EoC、IPQAM技术,为加快广电农网双改建设提供了理论和实践依据。

1,550 nm optical transmission technology has been the main trend of network transmission in Bureau of Radio and Television because the 1,550 nm optical transmission system network has a lot of features such as brief construction, convenient application, higher reliability, less investment and etc. Consequently, it is relatively ideal transmission plan in the case of double network and double changes of Bureau of Radio and Television. This article provides theory and practice basis from the calculation of C/N index of 1,550 nm optical transmission, applicable connect methods of front - end and optical node, and the combination of EPON, EoC, IPQAM technologies.
