Huizhou Optical Cable Selection Principles Optical cable is the main transmission tool for various information networks in today’s information society.
If the "Internet" is called the "information highway", then the optical cable network is the cornerstone of the information highway---the optical cable network is the physical route of the Internet.
Once a certain optical cable is damaged and blocked, the "information highway" in that direction will be destroyed.
In addition to the usual telephone calls, telegrams, and faxes, information transmitted through optical cables also includes television signals, bank remittances, stock market quotes, and other information that cannot be interrupted for a moment.
In addition to the number of fiber cores and fiber types, the selection of optical cables also depends on the use environment of the optical cables.
1. When outdoor optical cables are directly buried, armored optical cables should be used.
When used overhead, an optical cable with a black plastic outer sheath with two or more reinforcing ribs can be used.
2. When selecting optical cables for use in buildings, attention should be paid to their flame retardant, toxic and smoke characteristics.
Generally, the flame-retardant but smoke-free type (Plenum) can be used in pipes or forced ventilation areas, and the flame-retardant, non-toxic and smoke-free type (Riser) should be used in exposed environments.
3. For vertical cabling in the building, distribution cables can be used; for horizontal cabling, breakout cables can be used.
4. If the transmission distance is within 2km, you can choose multi-mode optical cable. If the transmission distance exceeds 2km, you can use relay or single-mode optical cable.
