Abstract
In an optical packet processing apparatus, an optical coupler joins optical packets transmitted through a plurality of input side optical transmission lines and outputs the joined optical packets to an output side optical transmission line. The optical packet processing apparatus has delay sections for delaying desired optical packets for each input side optical transmission lines. Delay times of the delay sections are different by one optical packet time period, while a minimum delay time thereof is the optical packet time period or more.
Claims10
An optical packet processing apparatus, comprising:
- a plurality of input side optical transmission lines to which optical packets are inputted;
- a plurality of delay sections which are provided in correspondence with each of the input side optical transmission lines and delays a desired optical packet of optical packets inputted from a corresponding input side optical transmission line;
- an optical coupler where optical packets transmitted from the input side optical transmission lines through the delay sections join;
- and
- an output side optical transmission line which outputs optical packets joined in the optical coupler,
- wherein delay times of the delay sections are different by one optical packet time period or more with respect to each other, and
- a minimum delay time thereof is the optical packet time period or more.
An optical packet processing apparatus, comprising:
- first and second input side optical transmission lines to which optical packets are inputted;
- a first delay section which is provided in correspondence with the first input side optical transmission line and delays a desired optical packet of optical packets inputted from the first input side optical transmission line for a first delay time;
- a second delay section which is provided in correspondence with the second input side optical transmission line and delays a desired optical packet of optical packets inputted from the second input side optical transmission line for a second delay time;
- an optical coupler where optical packets transmitted from the first input side optical transmission line through the first delay section and optical packets transmitted from the second input side optical transmission line through the second delay section;
- and
- an output side optical transmission line which outputs optical packets joined in the optical coupler,
- wherein a time difference between the first delay time and the second delay time is one optical packet time period or more, and
- one of the first delay time and the second delay time is the optical packet time period or more.
