Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical transmission wiring packaging system, in particular to an ultra-high density chassis without a tray. Background Art
[0002] With the application and development of optical fiber communication technology, new services such as voice / video / Internet triple-network integration and video on demand are growing, which puts higher requirements on the transmission speed and capacity of optical systems. Wavelength division multiplexing (WDM) technology supports the development of optical networks towards network densification, massive bandwidth and intelligent management. With its technical advantages of low equipment cost and low power consumption, WDM technology supports the development of FTTH networks in the metropolitan edge and access markets.
[0003] The shortcomings of the chassis related to the existing technology can be roughly summarized as follows: 1) The channel density of the fixed chassis is very high, but the cost is high. Some users do not need such a high-density channel, or do not need such a high density at the beginning of the project, but choose a pull-out chassis. Since the pull-out box has a small number of channels, the density cannot be too high in the later expansion. If multiple pull-out chassis are introduced, more cabinet space will be occupied, the wiring will be complicated, and the operating cost will be increased. 2) The types of boxes are single, and users have limited choices. 3) The existing chassis rail accessories are not smooth to pull out.
