无源光网络和其他技术进展预示了光纤本地接入系统的一个新纪元.TCM也被称作“光乒乓传输”,是一种光成组方式的时分复用技术.在考虑决定一个无源光网络(PON)的成本效益时,器件的成本无疑是一个最重要的因素.随着光刻技术的进展,将有可能将几种光功能集中到一个基片上.在频域中,可以通过使用SCM而保留带宽.由于近年来在光学、大规模集成电路(LSI)和用户环路设备几个方面的技术进展,已使光纤接入系统达到了较低的成本和较高的性能.
Passive optical networks and other advances in technology foreshadow a new era of local optical fiber access systems, also known as “optical ping-pong transmission.” TDM is a time-division multiplexing technique in optical grouping. After considering a passive optical The cost of a device (PON) is undoubtedly one of the most important factors when it comes to the cost-effectiveness of a network (PON). As lithography advances, it will be possible to focus several light functions onto a single substrate. In the frequency domain, SCM while preserving bandwidth due to advances in optical, large scale integrated circuit (LSI) and user loop equipment in recent years, the optical access system has been achieved with lower cost and higher performance.
