Zip Cord / Duplex Fiber Optic Patch Cable

Description
Duplex fiber optic patch cable is the optical fiber cable used in fiber optic patch cord. It adopts 2 core fiber optic whose radius is 900μm or 600μm. Outside the fiber optic is a layer of aramid yarn or high-strength yarn as superior strength member. The outermost layer of the fiber optic cable is a LSZH or PVC sheath. The outer diameter of the fiber optic cable usually is 2.0mm or 3.0mm. The bandwidth of the fiber optic cable can be 1000Mhz.Km when it is transmitting at a wavelength of 1300nm.

Applications
Optical fiber communication system
Fiber access network
Optical fiber data transmission
Optical fiber CATV
LAN
Fiber optic sensor
Duplex fiber optic connects patch cords or pigtails.
Indoor ventilation and wiring
Interconnection of instruments and communication devices

Features Using tight buffered fiber which is convenient for stripping. Tight buffered fiber has great flame retardant performance. The strength member which is made of aramid makes the fiber optic cable has great tensile performance. The figure 8 structure of the sheath is convenient for separating branches for use. The outer material has many advantages, such as: corrosion-resistant, waterproof, ultraviolet-proof, environmentally friendly and so on. The duplex fiber optic patch cable adopts all dielectric structure so that it will not be interfered by electromagnetic fields.
