Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical line terminals, in particular to an optical line terminal device for single-user access. Background Art
[0002] Optical Line Terminal (OLT) is a key device in Passive Optical Network (PON). It is located at the central office of the service provider and is mainly responsible for connecting the optical fiber trunk line and providing passive optical fiber network interface, as well as allocating bandwidth to users. OLT plays the role of endpoint hardware device in the PON system and is a vital part of the entire network connection performance. OLT equipment is a key component for realizing fiber to the home (FTTH) broadband connection. It works with ONU (Optical Network Unit) and ODN (Optical Distribution Network) to provide users with high-speed and reliable broadband access services.
[0003] Currently, most common optical line terminal devices are multi-interface terminal devices. For single-user use, this will cause redundant ports to be vacant or functions to be wasted, and the manufacturing cost is high. In addition, the multi-interface terminal devices are relatively large in size and require a certain amount of space for placement. In addition, traditional terminal devices are difficult to store power cords and have poor heat dissipation, resulting in a relatively short service life of internal components. In addition, the dust and moisture-proof effects are not obvious enough, and they can no longer meet the current growing demand. Utility Model Content
