  • Patent number: 10067307
    Abstract: Disclosed is a fiber optic splice protection device, comprising: a closure including a cover and a chassis; and at least one cable fixer for fixing cables to be spliced to the chassis of the closure. Wherein the cable fixer is a separate member separated from the chassis, and is removably mounted in the chassis of the closure; and all strength members of the cables to be spliced are previously fixed to the cable fixer before the cable fixer is mounted to the chassis of the closure. Therefore, it is possible that strength members of the cables to be spliced are once time secured to the chassis of the closure of the fiber optic splice protection device, so as to easy to implement rapid on-site installation. Further, the fiber optic splice protection device has higher mechanical strength.

  • Patent number: 10054750
    Abstract: A rail structure for optical fiber cassette is adapted to be assembled on a board member of a fiber box. The first engaging structure and the second engaging structure at two ends of the rail body are movably engaged with the first buckling structure and the second buckling structure. Hence, the user may detach one of the rail structures from the board member, so that the distance between the rest two of the rail structures goes wider, and the user can assemble another optical fiber cassette between the two rail structures, and the type and the size of the optical fiber cassette may be different from the detached one. Hence, the rail structure has wide applicability to allow the user to change the optical fiber cassette with different types and specifications conveniently and quickly.
