First, the core conceptoptical moduleFunctions similar to "photoelectric converter"Converting electrical signals (computer language) to optical signals (fiber optic language), or vice versaIt needs to be inserted into the switch and other devices for use.fiber optic transceiverIndependent

In the manufacturing process of optical cables, there are two key requirements for the protection of optical fibers: one is to minimize the physical stress on the fiber; the other is to ensure that the fiber has good waterproof performance.The structure of the fiber optic cable from the outside to t

Optical cable construction is a very important job. How to construct it in a standardized way? What are the technical requirements?Overview of communication optical cable engineering01Communication optical cable engineering is mainly divided into overhead optical cable engineering, direct buried opt

Pipeline Optical Cables① The optical cable in the hand hole should be protected by a serpentine hose (or soft plastic tube). The laid optical cable should be close to the wall of the hand hole and tied to the bracket with a plastic tie or processed according to the design requirements; at the same t

When using different optical cables for distributed optical fiber sensing, the following factors need to be considered in the selection:According to measurement requirementsStrain measurement: If high-precision strain measurement is required, optical fiber with polyimide (PI) coating can be selected

1.Briefly describe the composition of optical fiber? Answer: Optical fiber consists of two basic parts: the core and cladding, which are made of transparent optical material.   2. What are the basic parameters that describe the transmission characteristics of optical fiber lines? Answer: Including l

11.What is the backscattering method? A: The backscattering method is a method for measuring attenuation along the length of an optical fiber. Most of the optical power in the optical fiber propagates forward, but a small part is backscattered toward the light emitter. Using a spectrometer at the li

16. In current commercial optical fibers, which wavelength of light has the smallest dispersion? Which wavelength of light has the smallest loss? Answer: Light with a wavelength of 1310nm has the smallest dispersion, and light with a wavelength of 1550nm has the smallest loss. 17.How are optical fib

23.What does the armor of optical cable mean? A: It refers to the protective element (usually steel wire or steel belt) used in optical cables for special purposes (such as submarine optical cables, etc.). The armor is attached to the inner sheath of the optical cable. 24.What materials are used for
