Duct FTTH Optical Fiber Cable


Duct FTTH Optical Fiber Cable, Steel Wire Drop Cable, The structure of drop optical cable is as following:put the optical fiber unit into the middle of two non-metallic strengthening devices, then squeeze and lay layer of LSZH out of it. The structure of self-supporting drop optical cable is : add the metal hanging line, which is tight and has an excellent performance of high & low temperature resistance. The strengthened hanging line is made of high-carbon steel wirewith great tensile resistance. The fiber strengthen device has outstanding bending bending property. In addition, the sheath is consist with LSZH material withgood flame-retardance. The duct FTTH drop cable is to increase the waterproof & moistureproof outer sheath.


The optical cable hassmall diameter, lightweight, low cost, low construction cost.

It is suitable formechanical splicing technology, fast, and flexible.

The optical cable hashigh-tension and anti-squash force,self-supportingstructure can meet therequirement of 50 meters pull-fly.

Ituses aromaticpolyamide materials to be the strengthen material.

The optical cable issoft, good bending performance, and ensure that the bendingperformance can meetthe requirements.

It uses low smokezero-halogen material, ensure that the cable can meet therequirements for theflame-retardant materials indoor.

The optical fiber isthe bend insensitive fiber which can meet requirement of ITU-T G.657.

High-carbon steelwire should be used for Self-supporting strengthen device of optical cable,superior tensile properties contented.


With the development of the telecommunications industry, the communications networksdevelop from theunitary voice service to the full-service integratedcommunications network with various digital services of voice, data, and video.The construction ofoptical networks develops from the backbone network, corenetwork to the MANand access net works. Since the fiber  withfrequencybandwidth has the strengths of high transmission capacity and lowattenuation,FTTH supports various kinds of services, the features such aswider bandwidth,convenient maintenance are the foundation for our company todesign the dropoptical cable, which is applicable to the accession of the user’send in thebroadband access network. Indoor wiring & Into the building cable.
