Embodiment Construction

[0019] refer to figure 1 , the optical router 10 will be described according to the first embodiment of the present invention. Optical router 10 routes signals from a plurality of router input channels 12 , 14 , 16 and 18 to a plurality of router output channels 38 , 40 , 42 and 44 . Each router input channel 12, 14, 16 and 18 receives a signal to be routed. In one embodiment of the invention, each signal to be routed is a data packet in Internet Protocol ("IP") format - although other formats and standards may be used. Each IP packet has its intended destination, combined below Figure 7 , which will be better understood from this disclosure.

[0020] The optical router 10 includes an optical frequency router 20 . The optical frequency router 20 routes the optical signal corresponding to the wavelength or color, combined below Figure 8 , which will be better understood from this disclosure. The frequency router 20 has a plurality of input terminals 22 and 24 and a plur...

Abstract

An optical router is disclosed having at least one frequency router. The frequency router includes a plurality of input ports and a plurality of output ports. At least one input port simultaneously receives at least two optical signals to be frequency routed, while at least one output port simultaneously presents at least two frequency routed optical signals. Each optical signal to be frequency routed is colored in response to destination information.

Description

technical field [0001] The present invention relates to communications, and more particularly to optical routers suitable for Internet Protocol ("IP") communications traffic. Background technique [0002] The rapid growth of Internet traffic has created an increased need for more responsive Internet components. A component that is close to the working limit is the IP router. IP routers route traffic packets between destinations on the Internet. [0003] Currently, IP routers are appliance-based electrical switches. Commercial electrical switches available so far are based on IP routers with 16 input and 16 output channels. However, increasing the number of input and output channels poses great challenges due to issues such as space management, power consumption and heat dissipation, and electromagnetic interference. It should be believed that due to the limitation of the number of input and output channels, the electric switch based on IP router will soon reach the limit...
