The submarine communication cable is a wire wrapped with insulating material and laid on the seabed to complete the telecommunications transmission between countries. The first batch of submarine communication cables were used to supply telegraph communications, and later began to introduce telephone communications and Internet communications. Modern fiber optic cables also used fiber optic skills...

There are many kinds of optical power meters, which one is suitable for us? in choosing optical power timing, we should also consider the following factors: (1) Application. Ordinary optical power meters can generally measure the absolute optical power of ordinary optical fiber links, but in some special applications, such as passive optical network (PON), coarse wavelength division multiplexing (...

The difference between the two is that the pigtail is used to connect the optical cable and the jumper, and the jumper is to connect the pigtail and the terminal equipment. Optical fiber jumper is a jumper used from equipment to optical fiber cabling link, also known as optical fiber connector, which has a thicker protective layer and is generally used in the connection between optical transceiver...
