论证了一个用于分组交换的新的波长稳定技术。该技术稳定了发射机的长期波长漂移，而在WDM网络中使用监控通道易于稳定短期漂移和交换引起的波长漂移。精度、捕获范围和波长稳定方案的特性正在研究。对DBR激光器做长期波长稳定证明它可适合于通道间隔不大于30GHZ的WDM网络。
A new wavelength stabilization technique for packet switching is demonstrated. This technique stabilizes the long-term wavelength drift of the transmitter, whereas the use of a monitor channel in a WDM network tends to stabilize short-term drift and exchange-induced wavelength drift. The properties of accuracy, capture range and wavelength stabilization schemes are under study. Long-term wavelength stabilization of DBR lasers shows that it is suitable for WDM networks with channel spacings no greater than 30 GHz.
