Abstract

The invention discloses a low-loss bending-resistant fiber to the home. The low-loss bending-resistant fiber to the home is characterized in that a rare-earth-doped fiber core is adopted, an inner cladding layer and an outer cladding layer are formed on the surface of the rare-earth-doped fiber core from interior to exterior, and a primary coating layer, a buffering layer, a secondary coating layer and an outer protection layer are arranged on the surface of the cladding layer from interior to exterior in sequence. The low-loss bending-resistant fiber to the home is simple in structure, the transmission loss is effectively reduced, the brittleness of the fiber is improved, the bending performance of the low-loss bending-resistant fiber to the home is good, the low-loss bending-resistant fiber to the home can be directly arranged in the fields of indoor parts, electric control cabinets, ship electric devices and the like, and wiring connection is flexible and convenient.

Description

technical field [0001] The invention relates to a low-loss and bending-resistant home optical fiber, which belongs to the technical field of optical fiber communication. Background technique [0002] Optical fiber is increasingly widely used in the field of communication transmission due to its many advantages such as wide transmission frequency bandwidth, large communication capacity, low loss, and low interference compared with electromagnetic communication. Excellent working ability, multi-function, anti-electromagnetic interference and high precision. With the development of economy and society, the development of network puts forward new requirements for optical fiber. Next Generation Networks (NGN) will be the world of light at the delivery level and the wireless world at the access level. The next-generation transmission network requires higher speed and larger capacity, which is none other than optical fiber network. [0003] One of the development trends of optic...
