Analysis and application of fiber bending in high-speed optical communication
《Chinese Optics Letters》2014年第A01期23-24,共2页杨松 张晓光 席丽霞 赵东鹤 
Fiber Bending causes the bending loss, which mainly reduces the optical signal noise ratio （OSNR） of the optical transmission signal. When the fiber is bent to a certain degree, it will cause an interrupt signal. In...

Impairment-aware QoS provisioning in dual-header OBS networks
《Chinese Optics Letters》2011年第7期13-16,共4页樊玉琦 王斌 李廉 
supported in part by the National "973" Program of China under Grant No. 2009CB326203
Signal degradation due to physical impairments may result in unacceptable bit-error rates of received signals at the destination. Based on earlier work, we study the impairment-aware quality of service （QoS） provisi...
