Samjin (Opticube) Optical Closure

vsof-bs Samjin 403A
vsof-bs Samjin 403M


1.1. General

This specification covers the design requirements and characteristics required of fiber optic splice closures to be used on fiber optic cables for branch joint in various installation conditions such as aerial, manholes, ducts, wall and direct buried applications. It is specially designed for FTTH network and applicable to multi branching installation by using Mid-Plate which is for increasing core capacity and complying with the requirements in each point of network. The flat type gasket ensures reliable sealing performance by preventing air and water leak and the cone type sealing socket provides easy and reliable installation. This closure has high mechanical strength against any environmental conditions. With this splice closure, you can improve your network system to the higher level.

1.2. Description

Fiber Optic Splice closure for fiber optic cable may be exposed to severe environmental conditions. The splice closure for fiber optic cable shall provide excellent durability and longterm reliability in those severe conditions.

1.3. Reliability

The quality of a fiber optic splice closure is critical to reliable optical transmission performance. The product shall be produced with TL9000 certified production facilities and quality control system is applied the process from product design to packaging.
