FIBRE-OPTIC CARTRIDGE, SYSTEM AND METHOD Russian patent published in 2017 - IPC G02B6/38 

FIELD: optics.

SUBSTANCE: fibre-optic cartridge comprises body limiting front and opposite rear parts and closed inner part. Cable entry point is determined in body for cable entry inside cartridge. Cable included in cable entry point, is attached to cartridge body, and fibres pass in cartridge body and form end sealing connectors. Connectors are connected to adapters positioned on front part of cartridge. Front side of adapters determines connection point of cables intended for connection with fibres, connected to rear part of adapters. Cable includes shell, protective element and fibre, which enters into cartridge. Protective element is squeezed in squeezing tube and is installed on cartridge body, which allows fibres pass beyond squeezing tube inside cartridge body. Protective cap for compensation of cable tension is provided at cable entry point. Cable entry point is located in rear part of cartridge body opposite to front part. Adapters are arranged linearly along front part in one embodiment and extend in lengthwise direction parallel to main surfaces, limited by top and bottom parts of cartridge body. Cable at cable entry point passes parallel to longitudinal direction before entering cartridge body. Inside cartridge body cable bending radius limiters are located, which provide distribution of cable fibres passing from cable entry point to connectors on rear part of adapters. In one embodiment, unit of adapters with multiple adapters is made, including front end, rear end and inner structure, which provide conjugation with fibre-optic connectors at front end, for example SC or LC connectors. Unit of adapters can be detached from the rest part of cartridge. Rear part of unit of adapters forms rear clamp, which holds bushing with longitudinal cut and mounting socket and connector socket, in which sealed inner fibre is embedded, or rear end unit of adapters determines hole to receive SC or LC socket. Cartridge can be used on frame by fixed installation relative to frame or moving assembly, for example, at different sliding appliances to allow access to selected cartridge, thereby improving access to selected front connector, which is attached to cartridge.

EFFECT: faster, easier and more accurate connection/disconnection of fibre-optic cables from different sources.
