摘要:
An optical communication network system and a wavelength-routing device and a communication node therefor are provided which can easily increase the optical paths between communication nodes, which are capable of expanding transmission capacity, and which excel in flexibility and expandability. An optical signal within a wavelength band (λBm±Δλm) which has been transmitted from a predetermined communication node (200-1 through 200-4) is subjected to wavelength-band demultiplexing of the wavelength bands by wavelength-band demultiplexers (220-1 through 220-4) of a wavelength-routing device (210), and is then subjected to wavelength-routing by arrayed-waveguide gratings (241 through 244) according to the wavelength bands, and furthermore is multiplexed with optical signals of other wavelength bands by wavelength-band multiplexers (230-1 through 230-4), and after having been outputted, is transmitted to a communication node. In this manner, by varying the wavelength band (λBm±Δλm) of the wavelength of the optical signal which is transmitted from the communication node, it becomes possible to establish a single optical path between the communication nodes for each wavelength band.

A light-controlled light modulator can achieve high-speed, low-loss wavelength conversion. Continuous light with a wavelength λj is launched into an MMI coupler via a port, and is split into two parts by the MMI coupler, which are led to a loop-type interferometer. In the loop-type interferometer, the two parts travel separately around the loop as clockwise traveling light and counterclockwise traveling light, are combined by the MMI coupler again via a filter-equipped phase modulator, thereby being emitted to the port. In this state, signal light λi(s) with a wavelength λi is launched into the filter-equipped phase modulator via a port. Even when the wavelength λi of the signal light λi(s) is equal to the wavelength λj of the wavelength converted output light, the wavelength conversion can be achieved with preventing noise from being mixed into the output light emitted from a port.
摘要:
The invention achieves internet-based collaboration without having to install collaboration software on one of the computer. For example, a customer of a bank would like to collaborate with an agent of the bank. The customer accesses an external web server via a collaboration server. The collaboration server replaces a transition destination URL of HTML code acquired according to a request from the customer with a character string including a host name for the collaboration server and transition destination identification information and sends this character string to the user. When the customer clicks a link, the actual URL to be acquired is specified from the transition destination identification information at the collaboration server, and this URL is acquired by proxy and returned to the customer's browser. A browser monitor program then monitors the agent's browser, the URL to actually be acquired is specified based on transition notification from the collaboration server and the same HTML code as for the customer is acquired.
