GJFJBV Flat Duplex Tight Buffer Fiber Optic Zipcord Cable, 2mm/3mm, Indoor

Tight Buffered Fiber: Utilizes 900μm or 600μm tight buffered fibers to provide ease of stripping, along with reliable signal transmission.
Superior Flame Retardancy: Tight buffered fiber is highly flame resistant, which increases safety when used indoors.
Aramid Yarn Strength: Designed with added aramid yarn for exceptional tensile strength and durability for both installation and use.
Flat Zipcord Design: Flat, compact design keeps the fibers together and makes for easier routing in confined indoor spaces.
Robust PVC Jacket: The sheath is constructed of high grade PVC, offering corrosion resistance, waterproofing and environmental protection.
Customizable Sheath Options: Offered with LSZH or TPU jacket, based on safety and environmental specifications.
Easy Handling: Flexible and lightweight design for easy installation, management and termination.
Versatile Applications: Appealing for duplex patch cords, pigtails, interconnection of instruments, and indoor cabling associated with riser and forced ventilation applications.
International Standards: Constructed according to YD/T1258.3-2003 and IEC 60794-2-10/11 standards for quality and reliability.
Wide Temperature Range: Suitable for indoor applications that require operation within a temperature range from -20°C to +60°C.
