Introduction: Indoor-Outdoor Loose Tube Two Wire Cable is commonly known as Universal Loose tube Fiber Optic Cable. It is mostly Installed in riser ducts, cable trunks and under data center floors. It can also be made into a 2 to 12 cores structure with a cross-section Loose tube made of color coating fibers and filled with waterproof compounds. A layer of outer Jacket extruded outside the loose tube with two parallel metal Strength members embedded in the Jacket or black LSZH, UV resistant jacket with ripcord type shaped. Due to its small diameter and flexibility, the universal fiber optic cable is ideal for installation in cable trays. It can be installed in modern FTTH and FTTB systems, server rooms or connections between buildings. Other sheath materials are available on request. Application: Indoor-Outdoor Loose Tube Two Wire Cable bundles assemblies consist of a between 2~12 core, that enables installation of in building wiring applications. The fiber assemblies are bundled with outer sheath is a color coating fiber and filled with waterproof compounds. A layer of outer Jacket extruded outside the loose tube with two parallel metal Strength members embedded in the Jacket layer that is of low friction. This fiber cable is applied in Duct, cable trays and FTTx Access installations. Used in access network indoor and outdoor in customer premises network. Used as access building cable in premises distribution system, especially used in indoor and outdoor access cabling, the design makes the fiber cable are suitable for the following applications • Used as access building cable • Vertical Backbone Networks • Indoor and outdoor cabling • Distribution system cable Operation Features: The Indoor-Outdoor Loose Tube Two Wire Cable bundles for in building cabling systems are dedicated for indoor and outdoor network infrastructure. The small diameter is suitable to be used in projects requiring large number of slots and the fiber number between 4~24 core optical fiber cable which can be routed into ducts, and optical fiber cable with the following features • Flame retardant characteristics meet the requirements of relevant standards • Excellent temperature performance • Soft and easy to strip • High strength Loose Tube member • Small bending radius • Meet various requirements of market and clients • Excellent environmental properties • Perfect cable structure with high fiber density • Singlemode or Multimode • Fiber: G.652D, G.657A1, G.657A2 Temperature Performance: Storage and Transportation [°C]: -40 to +60 Installation [°C]: -20 to +50 Operation [°C]: -30 to +60 Mechanical Performance Test compliance: Tension: IEC 60794-1-21 Method E1 Bend: IEC 60794-1-21 Method E11 Crush: IEC 60794-1-21 Method E3 Marking: Indoor-Outdoor Loose Tube Two Wire Cable assemblies have markings showing the cable type and fiber number, Year of manufacture, Length marking. The individual fiber core is identified by their color according to the standard fiber colors.
