Precautions For Choosing Fiber Closure


Cable Compatibility
A good Fiber Closure shall be capable of accepting any Fiber Closure as specified in the tender document. Thus, it is vital to figure out the cable compatibility before selecting the right closure type. The design of fiber optic splice closure changes with the application areas. Therefore, a fiber optic splice closure for aerial will have different design from that used for underground application.

Termination System
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.

Numbers of Cable Ports
Cable port is also known as the cable entrance capacity. The number of ports in a fiber optic 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.

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.

Aerial fiber optic closures may need to hang on the messenger wire depending on the network configuration. Or they may be attached to the pole. In both cases, extra hardware is required along with the closures. The hardware to attach and secure should be able to bear wear and tear and also environmental stresses.

Greentelftth supplies fiber optic splice closures with different ports types, fittings and fiber optic core numbers. These splice closures are made of excellent engineering plastics and suitable for protecting optical fiber splices in straight through and branching applications, and can be used in aerial, duct and direct buried fiber optic cable projects. Fiber splice tray, fiber distribution box and fiber optic enclosure are also offered in conjunction with the splice closures, promoting a safe and well-managed environment for fiber optic splices. Custom service is available according to your requirements.
