Factors to Consider When Choosing Fiber Optic Closure


The optical network structure is often complex, especially the optical access part has unique requirements to function well. A reliable FOSC will eliminate lots of unnecessary issues. For example, for the network distribution system, a long-lasting, durable optical closure can avoid frequent check of the access link part. And as the network reaches the distribution stage and drop lines, a splice closure that allows adding more connections will be great. The following factors will help you to choose the right fiber optic splice closures and protect the fiber optics in your network.

1. Cable Compatibility

A good fiber optic closure shall be capable of accepting any fiber optic cable as specified in the tender document. Thus, it is vital to figure out 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 a depends on factors such as the network capacity and the number of cables employed in the network.

2. Numbers of Cable Ports

The 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 the number of cables employed in the network. Usually, in an attempt to reduce the physical sie of high-capacity

closures, smaller ports shall be utilized for branch cables and drop cables.

3. 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.

4. Types of Splices

The splice trays within the fiber optic splice closure can't hold enough cables if the cables do not be spliced properly. Usually, ribbon or mechanical splices have a larger

size, which may lead to capacity loss of the closure trays. A suitable configuration of the splices can avoid installation problems and help improve performance. Therefore,

the types of splices should be considered when choosing a fiber splice closure.

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.

6. Hardware and Accessories

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 or accessories to attach and secure should be able to bear wear and tear and also environmental stresses.

7. Cable Management

Keeping a low bend radius in fiber cables installations is important. The link performance may be affected if this factor is ignored. A fiber optic closure that can support

well cable management should be considered when making a choice. And splice closures that allow for easy installation can eliminate excessive stress or damage during
