40Gb/s系统技术解决方案探讨

Discussion on 40Gb/s system technology solution plan

4 0Gb/s系统的应用面临光信号的色散、衰减、交换、编码等方面技术的挑战。利用固定补偿模块或源色散补偿技术可以实现光的精确色散及补偿。赖曼式放大器对 4 0Gb/s系统的光传输提供了有力的技术支持 ,利用赖曼放大器以及全光交换机或光电光交换机则可以实现光信号的有效放大和高性能交换 。

Application of 40Gb/s system faces the challenge of technology in some respects , such as color dispersion,decaying,exchanging ,signal code,etc..Accurate dispersion and compensation of light can be realized by utilizing the regular compensative module or related technology of the compensation of the dispersion source .Lai Man's type amplifier offers strongest technical support to the transmission of light of 40Gb/s system . The optical signal can be amplified effectively and can be exchanged in the condition of higher performance by utilizing Lai Man's amplifier ,exchangers of light,exchangers of photoelectricity. Utilizing FEC technology and its corresponding code technology can improve the ability of the system in correcting error and the increasing transmission rate.
