众所周知,40G模块是下一代高速率和大容量的光网络核心技术与关键部件。伴随40G光模块大规模部署初现端倪,100G调制编码格式也渐渐浮出水面。面对众多特征各异的传输码型,在综合考虑其他系统设计参数的基础上,业界主要从传输距离、通路间隔、向下兼容、模块成本与传输性能的平衡等方面进行综合选择。目前,武汉电信器件公司(WTD)已相继成功开发了40G Transponder和CFP系列光收发模块产品,为设备商和系统集成商缩减开发周期提供了方便。WTD密切关注业界动向,在攻克了高速数字信号处理(DSP)技术与模数转换(ADC)技术方面的难关后,又将目光投向了相干光通信领域。
As we all know, 40G module is the next generation of high-speed and high-capacity optical network core technology and key components. With 40G optical module deployment began to take shape, 100G modulation encoding format has gradually surfaced. Faced with a large number of different transmission patterns, based on the consideration of other system design parameters, the industry mainly makes comprehensive choices in terms of transmission distance, path spacing, backward compatibility, balance of module cost and transmission performance, and the like. At present, Wuhan Telecom Devices Corporation (WTD) has successfully developed the 40G Transponder and CFP series of optical transceiver modules, which provides convenience for equipment manufacturers and system integrators to reduce the development cycle. WTD closely follows the industry trends and, after overcoming the difficulties of high-speed digital signal processing (DSP) technology and analog-to-digital conversion (ADC) technology, turns to the field of coherent optical communications.
