Fiber-optic cables transmit data via fast-traveling pulses of light. Another layer of glass, called “cladding,” is wrapped around the central fiber and causes light to repeatedly bounce off the walls of the cable rather than leak out at the edges, enabling the single to go farther without attenuation.
1.Send part: The pulse modulation signal output by the electrical transmitter (electric terminal) is sent to the optical transmitter. The main function of the optical transmitter is to convert the electrical signal into an optical signal and couple it into the optical fiber.
Patch Cord made in China can be purchased from Chaolian Electronic at low prices. It is a professional manufacturer and factory of high-quality products in China.
Compared with copper wire, optical fiber is much more fragile, so be extra careful during construction. Many examples of optical fiber splicing, connection, testing, and fault checking all tell us that improper operation can easily cause deterioration of optical fiber network performance.
Durability is a function of mechanical structure and materials. Connector durability is generally measured by vibration, drop, extrusion and bending tests
Patch panels and jumpers are important tools in the wiring of network cabinets, but you may confuse the two when using them.
