Optical fiber communications (Glass fiber)
Optical fiber communications using glass fibers are utilized for high-speed, large-capacity, and long-distance communications in trunk line networks and metro access networks.
Hamamatsu offers high-speed response photodetectors for use in transceivers in optical communication networks. In addition to photodiodes alone, we have a lineup of photodetectors with preamplifiers, receptacle-type and pigtail-type photodetectors, and can provide custom products to meet customer requirements.
These photodetectors are applied not only to transceivers but also to optical switches and light intensity/wavelength monitors.

1. What are cookies?
For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
