Optical Fiber Patch Cord is a type of fiber directly connected to a computer or device for easy connection and management. The following is a detailed introduction about the Optical Fiber Patch Cord:
Structure:
Core: It has a high refractive index and is used for transmitting optical signals.
Coating: With low refractive index, it forms a total reflection condition with the core, ensuring the transmission of optical signals within the core.
Jacket: High strength, able to withstand impact and protect optical fibers.
Type:
According to different application scenarios and interface types, Optical Fiber Patch Cord has multiple types, such as LC-LC dual core single-mode patch cords, MTRJ-MTRJ dual core multi-mode patch cords, etc.
The types of connectors include FC/SC/ST/LC/MU/MT-RJ, etc.
Specification parameters:
Diameter: usually available in different specifications such as 0.9mm, 2.0mm, 3.0mm, etc.
Polishing level: Depending on the application scenario and requirements, there are different levels such as PC, UPC, APC, etc.
Insertion loss: Depending on specific specifications and types, there are different requirements for insertion loss, such as SM PC type jumper insertion loss requirements of ≤ 0.3 dB.
Return loss: Return loss is also an important performance parameter, usually requiring ≥ 40dB (SM PC type).
Interchangeability: ≤ 0.2dB.
Working temperature: -40 ℃~+80 ℃.
Application:
Optical Fiber Patch Cord is mainly used to connect fiber optic transceivers and terminal boxes, achieving the transmission of optical signals.
It is widely used in fields such as spectral analysis and communication, such as using fiber bundles of different wavelengths and core diameters for spectral analysis.
The above is a detailed introduction about the Optical Fiber Patch Cord, covering aspects such as structure, type, specification parameters, and applications. For more information, it is recommended to consult professional books or consult with professionals in the relevant field.
