Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber jumpers, in particular to a waterproof card connector. Background Art

[0002] Optical fiber plays an extremely important role in the field of modern communications. It is widely used in many fields such as telecommunication networks, the Internet, and cable television. It is one of the key infrastructures for building information highways. It provides people with a high-speed, stable, and secure information transmission channel. The card connector is an interface for connecting optical fiber cables, which is usually used in optical fiber communication systems, optical fiber networks, and other fields.
