1.Summary of the 12cores horizontal type junction box
In order to meet the stringent protection requirements of fiber optic splices, fiber optic splice junction box, also called fiber splicing closures, are usually used to provide space for fiber optic cables to be spliced together. Fiber optic splice closures connect and store optical fibers safely either in the outside plant or indoor buildings. They can provide protection for the fiber joint and the fiber cables, since they have excellent mechanical strength and strong out shell, which ensure the joints not be damaged by the hostile environment.

1)Numbers of Cable Ports
Cable port is also known as the cable entrance capacity. The number of ports in a fiber optic splice closure reflects its capacity to handle the number of cables. The cable entrance capacity of a fiber optic splice closure refers to the number of ports available for terminating cable within the closure. The number of ports provided in a closure depends on factors such as the network capacity and number of cables employed in the network. Usually, in an attempt to reduce the physical size of high-capacity closures, smaller ports shall be utilized for branch cables and drop cables.
Before choosing the splice closure type, the cable termination system should be designed to provide sufficient mechanical strength between the cable and closure to ensure its performance throughout the lifetime. The materials used for fiber optic splice closures shall also be capable of minimizing or negating the effects of relative motion between cable components, because the materials used in optical fibers are easy to thermal expansion and contraction.
3)Bonding & Grounding
Proper bonding and grounding of conductive elements of the optical network shall be provided for the safe deployment and operation of the network.
