高频声纳基阵数据远程光传输设计

Design on the high-frequency sonar array data for remote optical transmission

在高频声纳系统中,为了实现大数据量、高速、远距离的数据传输功能,引进了千兆光网络疏波分复用(CWDM)技术和FPGA技术。采用FPGA进行基阵数据采集、编码、打包和分发工作,以16波分复用的千兆光网络模块实现仅通过两根光纤进行全基阵数据实时、最远80千米的传输功能。

CWDMtechnology and FPGA technology are used to realize the data remote transmission with the large volume and high speed for a high frequency sonar system. The FPGA is used to realize array data collection,coding,packaging and distribution. The CWDM with 16 wavelength channels is used to implement the transmission of all array data by only two optical fibersup to 80km.
