Working principle

FOXBORO P0973BU high-frequency fiber optic jumper is based on the principle of total reflection of light to achieve efficient transmission of high-frequency signals. The core process revolves around "optical signal coupling transmission reception", which is divided into three stages:

1. Optical signal coupling input: The transmitting end of industrial communication equipment (such as FOXBORO I/A series control modules, optical transceivers) converts high-frequency electrical signals into specific wavelength optical signals, and precisely couples the optical signals into the fiber core through the ceramic connector end face of the jumper. The high-precision grinding process of the connector ensures that the maximum amount of light energy enters the fiber core, reducing coupling losses.

2. Total reflection transmission of optical signals: The refractive index difference between the fiber core and the cladding (the refractive index of the fiber core is higher than that of the cladding) causes the optical signal entering the fiber core to undergo total reflection at the interface between the two, and the optical signal is confined inside the fiber core to continuously reflect and transmit forward, avoiding energy leakage. The coating layer and sheath isolate external light interference and physical damage, ensuring that the optical signal maintains high-frequency characteristics and stable intensity during transmission.

3. Optical signal coupling output: After the optical signal is transmitted to the other end of the jumper, it is efficiently coupled to the receiving device through a connector of the same specification. The receiving device then restores the optical signal to an electrical signal, completing the closed-loop transmission of high-frequency data. The entire process, due to the characteristics of optical signal transmission, effectively avoids the influence of electromagnetic interference on high-frequency signals and ensures transmission quality.

Precautions

-Connector protection: When not in use, a dust cap must be worn on the connector to prevent dust and oil contamination of the ceramic plug end face; Before use, gently wipe the end face of the plug with a degreased cotton soaked in anhydrous alcohol to avoid contamination that may cause increased insertion loss or damage to the plug.

-Cable operation specifications: Excessive bending or stretching of cables is strictly prohibited during wiring and storage, ensuring that the bending radius is not less than the specified value (static 15mm, dynamic 30mm) to avoid fiber core breakage; It is strictly prohibited to drag the connector part for cable movement to prevent the connector from loosening or being damaged.

-Installation environment requirements: Avoid installation and use in environments with high temperatures, open flames, and strong corrosive gases; When installed outdoors or in humid environments, it is necessary to use a waterproof junction box to prevent moisture from entering the connector and affecting its transmission performance.

-Safety operation warning: When the jumper is connected to the working optical equipment, it is strictly prohibited to look directly at the connector end face to avoid high-frequency laser damage to the human eye; When conducting link testing, it is necessary to confirm that the optical power is within a safe range and wear protective goggles during operation.

-Key points for troubleshooting: If there is an abnormal signal transmission, first check whether the connector is tightly inserted and whether the end face is clean; Visible laser pens can be used for on/off testing, or insertion loss can be measured using an optical power meter to determine if the jumper is functioning properly; Jumpers that are artificially damaged or exceed their insertion and removal lifespan should be replaced in a timely manner.

-Storage and transportation: When storing, the jumper wire should be coiled and placed in a dry and ventilated environment, avoiding direct sunlight and heavy objects from squeezing; During transportation, take measures to prevent falls and pressure to prevent damage to cables and connectors.
