Introduction: Round Drop Cable is commonly known as indoor hanging wiring cable. It is mostly single-core and double-core structure. It can also be made into a 4 to 12 cores structure with a cross-section of flat type shaped. The reinforcement is located at the center of the two circles. It can be made of metal or non-metal structure. The fiber is located in the geometric center of the flat shape. The fiber in the cable is made of G.657 small bending radius fiber, which can be laid at a bending radius of 20mm Application: The Round Drop Cable bundles assemblies consist of a between 1~12 core, that enables installation of FTTH Drop Cable. The fiber assemblies are bundled with outer sheath is a PE or LSZH layer that is of low friction. This fiber cable is applied in Duct, Aerial FTTx, Access installations. Used in access network or as access cable from outdoor to indoor in customer premises network. Used as access building cable in premises distribution system, especially used in indoor or outdoor aerial access cabling, the design makes the fiber cable are suitable for the following applications • Outdoor and Indoor connections • FTTH and last mile connections • Distribution networks with dense fiber capacity • Terminal connections Operation Features: The Round Drop Cable bundles for FTTx systems are dedicated for the outdoor and indoor network infrastructure. The small diameter is suitable to be used in projects requiring large number of slots and the fiber number between 1~12 core optical fiber cable which can be routed into ducts, and optical fiber cable with the following features • Smaller diameter • Excellent environmental properties • Perfect cable structure with high fiber density • The outer sheath is a PE or LSZH jacket • Fiber count between 1~12 core • Singlemode or Multimode • Fiber: G.G652D, 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: Round Drop 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.
