An optical access scheme for railway communication stations employing WDM and OADM
We have proposed an optical access scheme for railway communication stations based on physical bus and logical star DWDM-OADM architecture optical transport networks. The OADM optical nodes architecture was described
the logical dual-star architecture’s self-healing function was illustrated. We have demonstrated the logical single-star architecture network transmission performance and analysed the factors limiting the network scale.
