Introduction: Break-out Optic Cable is commonly known as vertical wiring in buildings cable. It is mostly Installed in walls, between floors, in plenum air handling ducts and under data center floors. It can also be made into a 1 to 48 cores structure with a cross-section of round type shaped. The multi-core branch cable will use several simplex optical cables made of 900μm tight buffered fiber and aramid yarns as optical sub-units. Sub-units are stranded together to form a cable core. Then a PVC sheath is extruded on the core. Other sheath materials are available on request. Application: The Break-out Optic Cable bundles assemblies consist of a between 1~48 core, that enables installation of in building wiring applications. The fiber assemblies are bundled with outer sheath is a PVC layer that is of low friction. This fiber cable is applied in Duct, Aerial FTTx, Access installations. Used in access network indoor in customer premises network. Used as access building cable in premises distribution system, especially used in indoor access cabling, the design makes the fiber cable are suitable for the following applications • Used as access building cable • Used as interconnect lines of equipment, and used in optical connections in optical communication rooms and optical distribution frames • Indoor cabling • Suitable for patch cord and pigtails, indoor distribution • Distribution system cable Operation Features: The Break-out Optic Cable bundles for in building cabling systems are dedicated for indoor network infrastructure. The small diameter is suitable to be used in projects requiring large number of slots and the fiber number between 1~48 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 Kevlar yarn 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: Break-out Optic 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.
