Part Number: FC-12-LZ-B-OS2-GF-ULT
The D-CONNECT Unitube Armoured Fiber Optic Cable is a compact, high-performance solution designed for backbone and distribution networks in both indoor and outdoor protected environments. Supporting 2 to 24 optical fibers, this cable is ideal for small to medium-capacity installations requiring dependable connectivity and long-term durability.
This cable is compatible with a wide range of fiber types, including OS2 for single-mode and OM2, OM3, OM4, and OM5 for multimode applications. It delivers high-speed data transmission and reliable performance across enterprise, telecom, campus, and data center networks.
To meet various environmental demands, the cable is available in three construction types:
Standard (non-armoured) for low-risk applications
Corrugated steel tape armoured for medium-risk environments
Steel wire armoured for enhanced mechanical protection
The gel-filled loose tube construction provides excellent protection against moisture, while water-blocking glass yarns add an extra layer of defense against water ingress. This ensures fiber integrity in harsh or variable conditions.
Lightweight and compact, the Unitube design makes installation easy in ducts, conduits, and indoor pathways. The cable offers excellent thermal stability and mechanical strength, performing reliably across a wide range of temperatures.
Available with either PE (Polyethylene) or LSZH (Low Smoke Zero Halogen) outer jackets, the cable can be customized to meet specific fire safety and installation requirements. Multiple jacket color options are also available for easier network identification and management.
The D-CONNECT Unitube Armoured Fiber Optic Cable is a reliable, versatile choice for modern fiber infrastructure, combining durability, performance, and flexibility in a cost-effective design.
The D-CONNECT Unitube Armoured Fiber Optic Cable is engineered and manufactured in accordance with leading international standards to ensure consistent quality, safety, and performance across diverse installation environments.
