Fiber Optic Splice Closure, also named Fiber Optic Joint Enclosure, is an essential passive component for fiber optic cable management in a fiber-optic network of backbone, MAN, and access network. Fiber Optic Splice Closure is widely used to protect optical fiber splices, store slack fiber optic cables, distribute fiber optic cables, etc. In straight-through and branching applications either in the outside plant or indoor buildings.

Fiber Optic Splice Closure can be installed in aerial, pole mounting, wall mounting, direct buried, and duct mounting.

According to the shapes of Fiber Optic Splice Closure, there are inline Fiber Optic Splice Closure (horizontal Fiber Optic Splice Closure) and dome Fiber Optic Splice Closure (vertical Fiber Optic Splice Closure).

According to the functions of Fiber Optic Splice Closure, there are standard Fiber Optic Splice Closure for fiber splicing and FTTH Fiber Optic Splice Closure for housing fiber optic splitters for FTTH Passive Optical Network.

LW-FOSC-IM288A-6 Inline Type Fiber Optic Splice Closure (FOSC) is mechanical sealing for reusable applications.

  • Easy access to installation, maintenance, and future expansions.
  • Excellent sealing against water ingress and harsh environment
  • Hinged splice trays for easy expansion without disturbing spliced fibers.
  • Compatible with standard normal fiber cable types
