摘要： The objective of the present invention is to realize a chromatic dispersion compensation method which does not depend on a wavelength path in a photonic network to which a HUB node is applied and its monitoring control. In order to achieve this purpose, the present invention controls a plurality of variable chromatic dispersion compensators arbitrarily disposed in the photonic network based on the measured results of a plurality of chromatic dispersion monitors arbitrarily disposed in the photonic network and wavelength path information kept by the network management system which manages the entire photonic network. Here, the variable chromatic dispersion compensator within the network that should be controlled and the chromatic dispersion compensated quantity thereof are determined based on the measured results of the chromatic dispersion monitor and the wavelength path information kept by NMS.

The construction is such that a part of excitation light of a 1480 nm band used in the C/L band optical amplifying section is supplied via an input terminal to a Raman amplification producing medium of a transmission path, and Raman amplified L band optical signals are input to the C/L band optical amplifying section.

摘要： A filling squeegee and a scraping squeegee are provided in a printing apparatus. The filling squeegee is moved without contacting a surface of a mask in order to fill a solder paste into openings of the mask. Unnecessary solder paste on the surface of the mask is scraped by the scraping squeegee. The solder paste is prevented from being improperly filled in or scraped from the openings even if a speed of the squeegee is increased, so that the solder paste can be printed stably on circuit board.
