With the implementation of the national broadband China strategy, the company has proposed and decided to start the indoor optical cable project, engaging in the production of indoor soft optical cables, optical jumpers, and optical devices. In 2014, the optical cable division was established, with 12 FTTH indoor soft optical cable production lines and 2 optical jumper production lines, with an annual output of 400,000 kilometers of indoor soft optical cables and 50 million optical jumpers. The main products are more than ten varieties in two series, including soft optical cables and butterfly optical cables. The company was put into production that year, completed more than 2 million sales that year, and completed more than 20 million sales in 2015. It has increased from four production lines to nine and now has 12 production lines. Lin'an has a large-scale jumper workshop. In 2016, the optical cable workshop completed more than 50 million sales, and sales exceeded 100 million in 2017.

From 2014 to 2015, the construction of a new plant of 25,000 square meters was completed, and the "30,000 kilometers of 4G mobile base station feeder project" with an investment of more than 70 million yuan and listed in the top ten key projects of Lin'an City was completed and put into production as scheduled. The company's products have successfully transformed from traditional coaxial cables to indoor optical cables and mobile 4G network base station feeders that the country has vigorously developed.

Sun Jianwen, chairman of the company, is the chairman of the Lin'an Wire and Cable Industry Association. He is an innovative entrepreneur. Under the guidance of the national broadband China strategy, he led the team to take them in completing product upgrades. The Zhejiang Lianfei Optical Fiber Industry Base Project, a joint venture with Wuhan Changfei, a domestic optical fiber and cable company, was put into production at the Hengfan Industrialization Base in Qingshan Lake Science and Technology City. The annual output value of the base can reach 1 billion, which can at least drive sales of more than 5 billion.

Installation and maintenance issues of Fiber Optical Cable of Hangzhou Putianle Cable Co., Ltd.

Fiber optic cables have become the backbone of modern communication systems due to their high data transmission capacity, low signal attenuation, and immunity to electromagnetic interference. Hangzhou Putianle Cable Co., Ltd. specializes in manufacturing high-quality fiber optic cables suitable for various applications, including telecommunications, data centers, and broadcast networks. Proper installation and maintenance are crucial for ensuring the reliability and longevity of these cables. 

Fiber optic cables consist of three main components: the core, cladding, and outer protective layers. The core, made of glass or plastic, is responsible for transmitting light signals, while the cladding reflects the light back into the core, allowing effective transmission. The outer layer protects the cable from environmental factors and physical damage.

Before installation, a thorough assessment of the site is essential. This includes identifying the installation environment (indoor or outdoor), potential electromagnetic interference, and existing infrastructure that may affect the installation process.

A detailed installation plan should be created, specifying the cable routing, required permits, and compliance with local regulations. Consideration should also be given to future expansion needs.

Fiber optic cables are sensitive and can be easily damaged. Proper handling techniques are crucial to avoid stress, bending, or crushing the cable during installation.

Cables should be stored in a climate-controlled environment, away from extreme temperatures, humidity, and direct sunlight. This helps prevent damage and degradation before installation.

During installation, it is vital to adhere to the manufacturer's specified minimum bending radius. Excessive bending can lead to micro-bending and macro-bending losses, resulting in degraded signal quality.

Adequate support should be provided along the installation route to prevent sagging or excessive tension. Cable trays, conduits, or brackets may be necessary to secure the cable.

Proper splicing techniques are essential for maintaining signal integrity. Fusion splicing is recommended due to its low loss and high reliability. Technicians should be trained in both fusion and mechanical splicing methods.

The installation of connectors should be carried out with precision. Poorly terminated connectors can lead to increased insertion loss and poor signal quality. It’s important to use high-quality connectors and follow the manufacturer’s specifications.

For outdoor installations, it is essential to use cables rated for environmental exposure, including UV light, moisture, and temperature fluctuations. Outdoor-rated cables typically have additional protective coatings.

When installing cables underground, proper burial depth and protective measures against rodents and other environmental hazards should be implemented. Conduits may be used for added protection.

Visual Inspections: Routine visual inspections should be conducted to identify physical damage, wear, or environmental impacts. Look for signs of fraying, exposure, or other visible issues that may affect performance.

Testing: Periodic testing using Optical Time Domain Reflectometers (OTDR) is crucial for identifying faults, breaks, or excessive losses in the fiber optic system. Testing should be performed after installation and at regular intervals thereafter.

Connector Cleaning: Dust, dirt, and other contaminants can significantly degrade performance. Regular cleaning of connectors with appropriate cleaning tools and solutions is necessary to maintain optimal signal transmission.

Fiber Cleaning: Fiber ends should be cleaned before splicing or termination to ensure maximum light transmission and reduce losses. Special fiber cleaning kits are available for this purpose.

When performance issues arise, it is essential to identify the source of the problem quickly. This may involve using diagnostic tools to locate faults or analyze signal loss within the system.

Any identified issues should be addressed immediately. This may involve re-splicing fibers, replacing damaged connectors, or rerouting cables to ensure the integrity of the system.

Monitoring the installation environment for temperature and humidity levels helps prevent potential damage. Extreme conditions can lead to cable degradation and signalloss.

Implementing additional protective measures, such as conduits, protective coverings, or shielding, can help safeguard cables from environmental hazards, physical damage, and rodent infestations.

By following best practices in installation and maintenance, users can maximize the performance and reliability of fiber optic cable systems, ensuring efficient communication and data transmission. Proper training and adherence to manufacturer guidelines will further enhance the effectiveness of installation and maintenance efforts, ultimately leading to successful long-term operations.
