Indoor Distribution Fiber Optic Cable
Indoor Distribution Fiber Optic Cable
D-type Indoor Cable
Key Features
- ● Excellent stripping performance of tight buffer fiber
- ● Aramid yarn as strength member providing good tensile strength
Applications
● Indoor cable distribution
● Backbone cable distribution in a building
Description
Indoor distribution fiber optic cables use φ900um tight buffer fibers as optical communication medium and aramid yarn as strength member units. The cables are completed with a PVC or LSZH jacket.
Specifications
indoor distribution fiber optic cables comply with standard YD/T 1258.4 and IEC60794-2-20/21
