This is a conventional Uniboot connector which can be used in high density assembly environment. Compared with the traditional dual connector, the product design structure is more compact, the overall height does not exceed the height of the compact adapter, and the use of single tube and dual core cables reduces the volume of the cable by half. It can effectively improve the hot air flow in high density crowded environment and make more reasonable use of energy efficiency.Using single-tube and dual-core cable, it can be used in high-density assembly environment with more compact structure. The overall height does not exceed the height of compact adapter. It is widely used in telecommunication network, CATV network, enterprise network and optical communication center.
