_1000-1000-1400x1400.png)
Application:
Used as a distribution cable for cabling inside buildings, in cable trays, in cable ducts, pipes, and tunnels.
Design:
The maximum count of optical fibers is 24.
The cable contains a bundle of tight buffer fibers which is covered with a layer of strength aramid yarn. The cable jacket is made of a flame retardant, halogen-free, low-smoke polymer composition.
The cable jacket is manufactured:
- yellow color for single mode fiber
- orange color for OM1, OM2 multimode fiber
- aqua color for OM3 multimode fiber
- pink color for OM4 multimode fiber
