Abstract

The invention provides a field optical network platform, which has a simple and compact structure, is convenient to mount and use, is safe and reliable, has a great heat dissipation effect, a wide application range and strong environmental suitability, and is suitable for outdoor environments. The field optical network platform comprises a platform shell, wherein the platforms hell comprises a shell upper cover and a shell bottom case, and the shell upper cover and the shell bottom case are rotationally connected; after rotating, the shell upper cover can cover the shell bottom case to form a sealed cavity; radiating fins are respectively arranged on the exterior of the shell bottom case and the exterior of the shell upper cover, and a heat-dissipation base plate is respectively fixed in the interior of the shell bottom case and the interior of the shell upper cover through fasteners; heat-conduction silicone grease is arranged between the heat-dissipation base plate and the shell bottom case and between the other heat-dissipation base plate and the shell upper cover; a power module, an EDFA module, an OLT module and a spool for cable routing, the power module is respectively in electrical-control connection with the EDFA module and the OLT module under, and a heat-dissipation layer is respectively arranged between the heat-dissipation base plate and the power module and between the other heat-dissipation base plate and the OLT module.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an outdoor optical network platform. Background technique [0002] The optical network platform is the central office equipment in the EPON passive optical network system, commonly known as OLT, which is a multi-service platform that supports both IP services and traditional TDM services. It is placed at the edge of the MAN or at the exit of the community access network to converge access services and transmit them to the IP network respectively. [0003] The EPON passive optical network system is flexible in networking, and multiple terminals at service access points within a radius of 20 kilometers are connected to form an EPON system network. The system can support a variety of business models, adapt to a variety of working environments, and provide users with FTTx series solutions. [0004] In addition to providing the function of service aggregation, OLT is also a c...
