The ultra bending insensitive single-mode optical fiber BendCom® G.657.B3 has outstanding bending performance, especially at 5 mm bending radius. The refractive index profile distribution is optimized so that the fiber can be fully compatible with G.657.A2 fiber, making it the best product for fiber-to-the-home (FTTH).
2.Home application scenarios such as invisible fiber optic cable
3.For occasions with special requirements to bending radius
1. Simple structure,light weight and high tensile strength.
2. Special groove design,easily strip and splice, simplified installation and maintenance.
3. Two parallel steel wires ensure tensile.
4. Crush resistance and flexibility.
5. Low smoke zero halogen and flame retardant sheath, environment-friendly and good security.

Color of connector
1 Nominal shipping length of the cable will be 1~3 km. Other length is also available if required by buyer.
2 Each length of the cable will be wound on a separate strong wooden.
3 Both ends of the cable will be sealed with a suitable heat shrinkable cap to prevent the entry of moisture during transportation and storage.
4 The cable end will be securely fastened to the drum to prevent the cable from coming loose during transit or becoming loose during placing operations.
5 Circumference battens will be secured between the outer edges of the flange to protect the cable against damage during shipment and storage.
6 For testing purposes, the inner end of the cable will be recessed into a slot in the drum flange . A minimum length of one meter of cable at the inner end will be accessible.
7 The cable will be shipped on drums designed to prevent damage to the cable during shipment and installation
8 The minimum barrel diameter of the drum will be 30 times to the overall cable diameter.
