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.

75 Ohm Qr Series Aluminum Tube Cable Industry knowledge

Impedance stability performance characteristics of 75 Ohm Qr Series Aluminum Tube Cable from Hangzhou Putianle Cable Co., Ltd.

The 75 Ohm QR Series Aluminum Tube Cable from Hangzhou Putianle Cable Co., Ltd. is designed specifically for high-frequency signal transmission. Known for its exceptional electrical characteristics and stability, this coaxial cable is widely used in broadcasting, television, satellite communication, and data transmission. One of its standout features is its impedance stability, which is critical for maintaining signal integrity and minimizing losses during transmission.

Impedance is a measure of how much a circuit resists the flow of electric current. For coaxial cables, maintaining a consistent impedance is crucial because it ensures efficient signal transfer. A standard impedance of 75 Ohms is ideal for video and RF applications. If the impedance is mismatched, it can lead to several issues:

Mismatched impedance causes part of the signal to be reflected back towards the source, resulting in interference and signal degradation.
Loss of Signal Integrity: High levels of reflection can distort the original signal, leading to a loss of quality, especially in high-definition applications.Variations in impedance can contribute to increased insertion loss, where the signal strength diminishes as it travels through the cable.

The QR Series Aluminum Tube Cable incorporates several design features that enhance its impedance stability:

The coaxial design inherently supports a uniform impedance along the length of the cable. This structure minimizes variations in the electromagnetic field, ensuring consistent performance.

The use of aluminum for the outer conductor not only reduces weight but also allows for precise control over the cable's physical dimensions. This precision helps maintain consistent impedance across varying lengths of cable.

The dielectric material used in the QR Series cable is designed to have low loss characteristics and stable dielectric constant, which is essential for maintaining impedance stability. This insulation minimizes signal degradation and reflection.

The center conductor's design is optimized to ensure a consistent electrical path. Whether using copper-clad aluminum or pure copper, the conductor’s geometry is engineered to provide uniform resistance and minimize signal loss.

To ensure impedance stability, the QR Series cables undergo rigorous testing during manufacturing:

Each batch of cable is tested for its impedance consistency using advanced testing equipment. This ensures that the impedance remains within ±1 Ohm of the specified 75 Ohm rating.

Return loss, which quantifies the amount of reflected signal, is measured to ensure minimal signal reflection. A higher return loss value indicates better impedance matching.

TDR is employed to analyze the cable’s response over distance, identifying any irregularities in impedance that could lead to performance issues.

The cable’s performance is also evaluated under varying environmental conditions. Consistency in impedance under these conditions is crucial for outdoor and industrial applications.

The stable impedance characteristics of the 75 Ohm QR Series Aluminum Tube Cable make it suitable for a range of applications:

In these applications, high-quality signal transmission is critical. The impedance stability ensures that video signals remain clear and undistorted, crucial for HD broadcasts.

The cable's performance in high-frequency ranges makes it ideal for satellite applications where signal integrity is paramount for effective communication.

The QR Series cable is also suitable for high-speed data transmission, where stable impedance helps reduce latency and maintain high data rates.

In video surveillance systems, the cable’s ability to deliver high-quality video signals without degradation ensures that monitoring systems function effectively.

The 75 Ohm QR Series Aluminum Tube Cable from Hangzhou Putianle Cable Co., Ltd. stands out for its exceptional impedance stability performance. With a design focused on maintaining consistent impedance, the cable ensures high-quality signal transmission across various applications. Through rigorous testing and high-quality materials, this cable provides reliable performance, making it a preferred choice in broadcasting, satellite communication, and data transmission sectors. By investing in such a cable, users can enhance their systems’ overall performance, ensuring clarity, integrity, and reliability in signal delivery.
