In a loose-tube cable design, color-coded plastic buffer tubes house and protect optical fibers. A gel filling compound impedes water penetration. Excess fiber length (relative to buffer tube length) insulates fibers from stresses of installation and environmental loading. Buffer tubes are stranded around a dielectric or steel central member, which serves as an anti-buckling element.
The cable core, typically surrounded by aramid yarn, is the primary tensile strength member. The outer polyethylene jacket is extruded over the core. If armoring is required, a corrugated steel tape is formed around a single jacketed cable with an additional jacket extruded over the armor.
Loose-tube cables typically are used for outside-plant installation in aerial, duct and direct-buried applications. Read More
Fiber optic cable, also know as optical fiber cable, is a type of Ethernet cable which consists of one or more optic fibers that are used to transmit data. It is an assembly similar to an electrical cable while it is used to carry light and the fiber optic cable price is much higher than that of copper cable. Designed to use light pulses, fiber optic cables support long distance telecommunication and high-speed data transmission. Normally, fiber optic cable can run at a speed of 10 Gbps, 40 Gbps and even 100 Gbps. Therefore, it is widely used in much of the world's internet, cable television and telephone systems. Read More
