Custom Optical Fiber Splice Closure Manufacturers

Why is the protection level of the optical fiber splice closure so important?

The protection level of the fiber optic splice box is very important, mainly reflected in the following aspects:
1. Ensure the long-term stability of the fiber optic connection
Fiber optic splice closures are often used outdoors or in extreme environments, such as roadsides, underground pipelines, and outside buildings. The protection level (usually expressed as IP level) directly affects whether the fiber optic splice box can effectively resist external factors such as water, dust, and pollutants to maintain the stability of the fiber optic connection. Poor protection may cause the fiber optic connector to be damp, corroded or damaged, which in turn affects the communication quality and reliability of the entire fiber optic network.
2. Waterproof and moisture-proof performance
Waterproofing is a key factor in the protection level of the fiber optic splice closure. Many fiber optic splice boxes are required to have a high waterproof performance (such as IP65 and above) to prevent rain or moisture from penetrating into the splice box. Moisture or water entering the splice box will cause oxidation or short circuit of the fiber optic connection point, resulting in fiber optic signal attenuation or complete failure.
3. Dust and pollution resistance
Dust resistance is another important protection factor. Fiber optic splice closures with high protection levels (such as IP68) can prevent dust, sand, pollutants, etc. from entering the box, which is essential for the precise connection of fiber optic splices. Dust or impurities entering the splice box may interfere with the quality of the fiber optic connection and cause signal loss or attenuation.
4. Improve service life
Splice boxes with high protection levels can better resist the erosion of the external environment on the equipment, such as extreme temperatures, ultraviolet rays, wind and sand, etc. By improving the protection ability of the splice box, its service life can be effectively extended, maintenance costs can be reduced, and the failure rate can be reduced, thereby ensuring the stable operation of the fiber optic network.
5. Adapt to various installation environments
optical fiber splice closures are widely used in various environments, including underground, ground, humid, windy and sandy, low temperature or high temperature areas. Different environments have different requirements for splice boxes. The protection level can ensure that the fiber optic splice box can maintain good working condition in various extreme environments and avoid equipment failures caused by environmental changes.

How to choose a suitable fiber optic splice box?

Choosing a suitable fiber optic splice box is an important part of ensuring the stable operation of the fiber optic network. A suitable splice box can not only protect the fiber optic connector from the external environment, but also improve the maintenance efficiency and reliability of the system. The following key factors need to be considered when choosing:
1. Installation environment
Outdoor or indoor?
If the fiber optic splice box will be installed in an outdoor environment (such as a street, power pipeline or communication tower), it is necessary to select a fiber optic splice box with a higher waterproof and dustproof level (usually at least IP65 and above) to prevent external factors such as rain and dust.
Temperature and humidity range:
If the installation environment has a large temperature difference or high humidity (such as underground pipelines or humid areas), it is necessary to select a fiber optic splice enclosure with good temperature and humidity adaptability and moisture-proof function.
UV resistance:
If the fiber optic splice box is exposed to strong sunlight (such as an exterior wall), a shell material with UV resistance should be selected to avoid UV rays accelerating material aging.
2. Fiber type
Single-mode fiber or multi-mode fiber:
When selecting, the specifications of the splice box should be determined according to the type of fiber used (single-mode or multi-mode). Different types of fiber optic connections, the number of connectors, and layout requirements may vary, so make sure that the splice box can accommodate the required number of fiber optic connectors.
Number of fibers:
Choose the appropriate splice box capacity based on the network size and needs. For example, if you need to handle more fiber optic connectors, you can choose a large-capacity fiber optic splice box (such as a 48-core or 96-core splice box).
3. Protection level
The protection level (IP level) determines the dust and water resistance of the fiber optic splice box. Common IP levels are:
IP65: dustproof and can withstand water spray;
IP67: dustproof and can be immersed in water for a short time;
IP68: completely dustproof and can be immersed in water for a long time.
Choosing the right protection level can ensure the effective protection of the fiber optic splice box in different environments, especially for outdoor or harsh environments, where waterproof and dustproof are very important.
4. Splice box material
The material of the fiber optic splice box directly affects its durability and reliability. Common splice box materials include:
Plastic: Lightweight and low-priced, suitable for general environments, suitable for small and medium-sized fiber optic splice boxes.
Metal: More durable, corrosion-resistant, suitable for harsh environments (such as high temperature or highly corrosive areas).
Choose the right material according to the installation environment.
5. Easy to install and maintain
The design of the fiber optic splice box should be easy to install and maintain later. Choose those splice boxes with clear structure, easy connector connection and simple operation. For example:
Detachable design: Convenient for later inspection, adding or removing optical fiber.
Modular design: Convenient to increase or decrease optical fiber connectors as needed, with strong flexibility.
Fasteners: Choose with anti-loosening screws or lock design to avoid loosening due to vibration or external force during long-term use.
6. Installation method
The fiber optic splice box can be installed in a variety of ways:
Wall-mounted: Suitable for installation on walls, communication rooms or brackets.
Direct burial: Suitable for fiber optic splice boxes used in underground pipelines or buried underground.
Overhead: Suitable for situations where optical fiber needs to be installed overhead, such as on power poles.
Choose the appropriate installation method according to the actual installation scenario.
7. Durability and lifespan
The durability of the fiber optic splice enclosure is the key to long-term operation. Products with good material quality, aging resistance and strong impact resistance should be selected, especially for outdoor installations, where the splice box needs to resist long-term erosion from the external environment.
8. Cost and budget
When choosing a fiber optic splice enclosure, price is also a factor to consider. According to the scale and budget of the project, reasonably balance cost and performance. Under the premise of ensuring functionality and quality, choose products with high cost performance.
9. Certification and standards
Ensure that the fiber optic splice box meets relevant industry standards and certifications (such as CE certification, RoHS environmental certification, ISO quality certification, etc.). These certifications can guarantee product quality and ensure that it meets international and regional safety standards.
