摘要
概述了长途超大容量(Tb/s级)DWDM光通信设备特点及关键技术要求,包括系统光学特性优化、高速高性能光转发、大容量合分波技术、宽带混合放大技术、智能化分系统及高可靠性电气系统等方面;提出了光通信设备智能化控制子系统概念,配合自动化辅助维护功能,对网络管理提出较高要求。最后简要叙述长途超大容量设备的发展水平,探讨在长途超大容量设备技术支撑下的下一带光传输设备新特点。
Key technologies and issues of the ultra-high capacity long haul DWDM optical fiber communication equipment are introduced in this paper, including high speed and good performance transceiver, high capacity MUX/DE-MUX, broad bandwidth hybrid amplification, and optimization controlling of optical performance. A concept of intelligent subsystem is introduced, combining with automatic auxiliary maintenance, to be a senior requirement for system management. Status and future promises for ultra high capacity long haul equipment in the next generation optical fiber transmission system are summarized.
