- Product Introduction
Underground Fiber Optic Junction Box Telecom Manhole Chamber is used for underground cable connection, or for cable installation and subsequent maintenance of telecommunication equipment.
The telecom manhole is made of sheet molding compound (SMC) material, which has high material strength and climate stability, while the total weight is 1/10 of the traditional concrete material.
Overall EPC costs will be lower by reducing installation time and requiring less personnel and equipment. The Underground Fiber Optic Junction Box Telecom Manhole adopts a unique " assembled structure " design, that is, when it is delivered to the destination, it will be disassembled into plates, and the transportation space will be 1/4 of that of traditional prefabricated manholes - which means that the total transportation and logistics will be reduced 3/4.
Pre-drilled SMC panels have been left on each side of the access hole and can be easily knocked out as needed during wiring. It saves the time and cost of drilling holes on site.
