The indoor multi-core distribution cable structure is based on tight-buffered optical fiber as the basic unit. The multi-core bundled cable is used as a subunit and is twisted into a circular shape with FRP and then extruded into a PVC (or LSZH) sheath to form a cable. Between the core and the sheath, a dry water blocking material is placed.
1. Used in indoor cabling
2. Used in optical connections in optical communication equipment rooms and distribution frames
3. Used in optical connections in optical equipments and apparatus
4. Used as pigtails and patch cords
