Multimodal fiber

In the multi -mode fiber, the diameter of the core is 15 μm ~ 50 μm, which is roughly comparable to the thickness of the human hair. The diameter of the single -mode fiber core is 8 μm ~ 10 μm. A glass cover with a lower refractive index is surrounded by a glass cover to keep the light in the core. The outside is a thin plastic jacket to protect the cover.

advantage:

Frequency bandwidth:

Adopt advanced related optical communication can arrange 2,000 light carrier waves within 30,000GHz, which can be replicated, which can accommodate millions of channels.

Low loss

The power loss of the coaxial cable is doubled, so that it can be transmitted far more.

Light weight

Fiber is very fine. The diameter of the optical cable composed of 4 to 48 fiber is less than 13mm, which is much smaller than the diameter of the standard coaxial cable 47mm. In addition, the optical fiber is glass fiber and the proportion is small. Very convenient.

Strong anti -interference ability

The basic component of the fiber is quartz, only transmission, non -conductivity, and not subject to the effect of electromagnetic fields.

High degree of preservation

Fiber transmission generally does not need to be enlarged, and will not be caused by enlarged new non -linear distortion. As long as the laser is linear, the signal can be transmitted highly.

Reliable work performance

The number of equipment contained in the fiber system is small (unlike the cable system requires dozens of amplifiers), and the reliability is naturally high. In addition
