Recently, the first photovoltaic tunnel lighting system in Yantai Tongshi Road Tunnel, which is the first in China, was successfully put into operation and officially opened. The project saved 42 tons of standard coal per year, and the annual saving cost was nearly 200,000 yuan.
On the top of the south exit of the Tongshi Road Tunnel, you can see that in a square of 3,000 square meters, a row of dark blue solar panels is spectacular. This is the solar photovoltaic power station of the Tongshi Road Tunnel. Lin Shile, head of the Housing and Construction Bureau of Yantai City, told the author that the photovoltaic system of the Tongshi Road Tunnel is the first in China to apply solar energy in tunnel lighting.
FTTH is an optical fiber directly to the home of the foreign language abbreviation, the Chinese abbreviation for fiber to the home. Specifically, FTTH refers to the optical network unit (ONU) installed in the home user or business users, is the optical access network in addition to FTTD (fiber to the desktop) closest to the user's optical access network application type. A significant feature of the FTTH is not only to provide greater bandwidth, and enhance the network transparency of data format, rate, wavelength and protocol, the relaxation of environmental conditions and power supply requirements, simplify maintenance and installation. Speaking of FTTH, first of all, we must talk about fiber access. Optical fiber access refers to the end of the transmission between the user and the fiber as the media. Fiber access can be divided into active optical access and passive optical access. Optical fiber transmission technology is the main technology of optical fiber subscriber network. At present, the multiplexing technology of optical fiber transmission is developing very fast, and most of them have been applied in practice. According to the depth of the user's degree of fiber, can be divided into FTTC, FTTZ, FTTO, FTTF, FTTH, etc..
