Description
2-12F 6.0mm Central Loose Tube cable has its optical fiber unit positioned in the center of a high – hardness PBT loose tube. This tube offers very good protection to the fiber. A glass yarn surrounds the PBT tube. The glass yarn offers very good anti – rat performance to the cable. Then, the cable is completed with an LSZH sheath.
Our cable features a small diameter, water – resistance, softness, and bendability. It is easy to deploy and maintain. In addition, the non – metallic strength member can provide lightning protection and anti – electromagnetic interference. Round FTTH Drop cables are ideal for indoor cabling, direct end – user cabling, and access networks.
