QB-H is a quick-connect bayonet connector designed specifically for high-power laser transmission. It is widely used in industrial laser processing, medical laser equipment and other scenarios. Its core features are high power carrying capacity, fast plug-in and pull-out, and stable optical performance.

QB-H Fiber Optic Connector

Structural Features

1. Interface Design: The bayonet locking structure is adopted, and the connection or disconnection can be completed by rotating 1/4 turn. It is easy to operate and suitable for working conditions that require frequent plugging and unplugging.

2. Cooling and protection: High-power models often integrate water cooling channels or heat dissipation structures to avoid overheating of the connector due to excessive laser energy; the shell is made of wear-resistant metal, with impact resistance and corrosion resistance, and the protection level can reach IP67, which is suitable for harsh industrial environments.

3. Safety Design: Built-in interlocking device, when the connector is not fully locked, the laser source cannot be started to prevent safety hazards caused by light leakage.

Advantages: fast connection, high power compatibility, high safety, strong environmental resistance, it is one of the standard interfaces of industrial high-power laser systems.

QB-H optical fiber

QB-H optical fiber is a high-power transmission optical fiber used with QB-H connectors. Its design needs to match the interface parameters of the connector and meet the low loss and damage resistance requirements of high-energy lasers.

Structural features:

1. Coating and buffer layer: The core is wrapped with a low-refractive index cladding, and the outer layer is coated with a high-temperature resistant polymer or metal coating to enhance mechanical strength and resistance to laser damage; some models use double coating to improve bending resistance.

2. Anti-damage design: The end face of the core is specially treated to reduce end face burns caused by light reflection; the optical fiber has high purity, reducing absorption loss and heat accumulation caused by impurities.

3. Bending performance: It has a certain bending resistance, but it needs to follow the minimum bending radius to avoid increased loss or fiber breakage caused by excessive bending.

Applicable scenarios: As the core transmission medium of the QB-H system, it directly connects the laser generator and the processing head to undertake the transmission task of high-power lasers.

QB-H fiber optic cable

Structural composition:

Core optical fiber + sheath and reinforcement layer + connectors at both ends.

Application areas:

Industrial laser cutting, laser welding, laser surface treatment;

High-power medical laser equipment;

High-power laser experimental system in the field of scientific research.

In summary, the QB-H series is a standardized solution for high-power laser transmission：

The connector provides a fast and secure interface; the optical fiber ensures high-energy and low-loss transmission;The cable integrates the two to form a complete "end-to-end" energy transmission link. The three work together to meet the high efficiency and reliability requirements of high-power laser systems in the industrial and medical fields.
