Fiber optic distribution box material introduction

The material selection of optical fiber distribution box (usually called optical fiber distribution box or ODF box) has an important impact on its performance, life and safety. The following is an introduction to the common materials of optical fiber distribution box:

1. SMC composite material

Composition: SMC (Sheet Molding Compound) composite material is mainly composed of SMC special yarn, unsaturated thermoforming resin, organic fiber reinforced plastic, low shrinkage additives, filler and auxiliary synthetic agent.

Features: moisture, dust, water, corrosion resistance, anti-aging performance, long service life, up to 50 years. At the same time, it has good mechanical strength and protection level (such as IP65 level), which can resist the impact of external shocks and environment.

Application: Due to its excellent performance, SMC composites are widely used in the production of optical fiber distribution boxes, especially in extremely harsh environments. However, due to its high cost, it may be used less in some cost-sensitive application scenarios.

2. Cold rolled sheet

Features: Cold-rolled sheet has good stamping performance, high flatness, high surface finish, and easy to be coated. The steel plate obtained by the cold rolling process has thinner thickness and higher precision, and is suitable for the production of boxes requiring certain strength and corrosion resistance.

Application: Cold-rolled plate is one of the commonly used materials of optical fiber distribution box. After spraying, the box looks beautiful and durable. It is suitable for fiber optic network deployment in a variety of environmental conditions, including indoor and outdoor environments.

3. Stainless Steel

Features: Stainless steel has excellent corrosion resistance and mechanical strength, and can maintain stable performance in a humid and corrosive environment for a long time.

Application: Stainless steel fiber optic distribution box is especially suitable for occasions with high material requirements, such as Marine environment, chemical industry park, etc. Despite its relatively high cost, its long-term stability and reliability make it preferred in some specific application scenarios.

4. ABS material

Characteristics: ABS (Acrylonitrile Butadiene Styrene) material has good processability, impact resistance and heat resistance. However, its aging resistance and corrosion resistance are relatively weak.

Application: ABS material is often used to make fiber optic distribution boxes with low cost, which is suitable for occasions where the material requirements are not very harsh. It should be noted that the overall performance of the pure ABS material fiber box may be slightly reduced, so the cost performance should be considered comprehensively when selecting.

5. PC+ABS alloy material

Characteristics: The alloy material of PC (Polycarbonate) and ABS combines the advantages of high transparency, high impact strength of PC and weather resistance and processability of ABS. This material not only has excellent mechanical properties, but also has good processability and cost effectiveness.

Application: PC+ABS alloy material is widely used in the field of optical fiber distribution box, especially in the need for high quality and moderate cost occasions. It is able to meet the needs of most fiber network deployments while maintaining low production costs.

In summary, the fiber optic distribution box has a variety of material choices, and each material has its own unique characteristics and application scenarios. In the selection, it is necessary to comprehensively consider the actual needs and budget to ensure that the selected material can meet the performance, life and security requirements of the optical fiber network.
