This round ftth cable is mainly used for the optical cable connections from outdoor to indoor in access networks or user premises networks, it is also applicable to the building lead-in cables in structured cabling, especially for wiring during indoor or outdoor aerial lead-ins.
It must comply with relevant standards such as IEC 60794 and undergo a series of tests including temperature and humidity cycling tests, tensile strength tests, mechanical impact tests, and optical fiber core reflection tests to ensure its performance meets the requirements.
Typically this ronnd cable includes optical fibers, strengthening components, and an outer sheath. Optical fibers are usually single-mode fibers, such as types G.652D, G.657A1, and G.657A2. The strengthening components are used to enhance the mechanical performance of the cable, commonly made of steel wire, glass fiber reinforced plastic (FRP), aramid yarn, etc. The outer sheath materials are mostly low smoke zero halogen flame-retardant polyolefin (LSZH), polyurethane (TPU), or PVC, which have good weather resistance, flame retardancy, and mechanical protection performance.
