Communication optical cable is a kind of communication line that a certain number of optical fibres constitute the cable core in a certain way, which is covered with a sheath and some with an outer sheath to realize optical signal transmission.

Communication optical fibre is a kind of optical transmission tool based on the total reflection principle of light in glass or plastic fibre, which is usually used for long-distance information transmission.

Generic cabling is a modular and highly flexible information transmission channel in buildings or between buildings. Including: transmission medium, relevant connecting hardware (such as distribution frame, optical fibre jumper, optical fibre pigtail, socket, plug, adapter) and electrical protection equipment.
