• Product Details

Product Introduction:

    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).
 Application Scenarios:
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.

1.The equipment is used as a termination point for the feeder cable to connect with drop cable in FTTx communication network system. The fiber splicing, splitting, distribution can be done in this box, and meanwhile it provides solid protection and management for the FTTx network building.

2.Cabinet can be installed by the way of wall-mounted or poled-mounted, suitable for both indoor and outdoor uses.

3.Products are widely used in telecommunications, broadcasting and other fields. Television, power engineering, and other industries. The main market distribution: Russia and other CIS, South Africa, Europe, South America, etc.

4.A fiber optic patch cord is a fiber optic cable capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunication equipment.


Shenzhen Kexint technology co.,ltd which was founded in the year 2007 is a high-tech enterprise specialized in telecom communication network equipment research and development (R&D), manufacturing, marketing, and providing application solutions and technical services .Rich experiences in passive production of fiber optical products ensure the reliable stabilities of its high quality and excellent performances of its goods. It obtains the good reputations all these years from customers around the earth for its short lead-time, fast delivery, and timely after-services.

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.
