What’s the requirements for a fiber optic splice closure?
As we have known, fiber optic splice closures play an important role in optical cable network. And according to the environment and working area, fiber optic network operators specify the requirements for the joint closures. However, there are certain common requirements that every fiber optic splice closure shall meet. Here are these requirements.
A fiber optic splice closure shall be capable of accepting any fiber optic cable as specified in the tender document. Therefore, it is necessary to find out the cable type before deciding on the closure type. The design of fiber optic splice closures changes with the application areas. Thus, a fiber optic splice closure for aerial will have different design from that used for underground application.
2)Number of ports
Number of Ports, 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.
3) Additional capacity
Additional capacity is retained by closure manufacturers. For example, if the specification requirement is 48 fibers, manufacturers often provide enough capacity to deal with 60 fibers.
4) Termination system
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.
5)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.
