摘要:
A time division multiplexed optical switching system switches a signal from an ingress port to an egress port. The system comprises an optical switching fabric, ingress and egress line cards and a switch control fabric. The optical switching fabric routes an optical signal from one of M ingress fibers to one of N egress fibers. The ingress line card is coupled between the ingress port and the optical switching fabric for receiving the signal at the ingress port. The ingress line card comprises a buffer for storing the ingress signal and transmits the signal to the optical switching fabric. The egress line card is coupled between the egress port and the optical switching fabric for receiving the optical signal from the egress fiber of the optical switching fabric. The egress line card comprises a buffer for storing the optical signal and transmits the signal to the egress port. The switch control fabric allots time slots to the ingress line card for transmitting to the optical switching fabric.
摘要(中):
时分复用光交换系统将信号从入口端口切换到出端口。 该系统包括光交换结构,入口和出口线卡和交换机控制结构。 光交换结构将来自一个入口光纤的光信号传送到N个出口光纤之一。 入口线卡耦合在入口和光交换结构之间,用于接收入口端口的信号。 入口线卡包括用于存储入口信号并将信号发送到光交换结构的缓冲器。 出口线卡耦合在出端口和光交换结构之间,用于从光交换结构的出口光纤接收光信号。 出口线卡包括用于存储光信号并将信号发送到出口的缓冲器。 交换机控制结构向入口线卡分配时隙以发送到光交换结构。
