Drop cable, as an important part of the FTTH network, forms the final external link between the subscriber and the feeder cable. Choosing the right FTTH drop cable will directly affect network reliability, operational flexibility and the economics of FTTH deployment.

What Is FTTH Drop Cable?

FTTH drop cables, as previously mentioned, are located on the subscriber end to connect the terminal of a distribution cable to a subscriber’s premises. They are typically small diameter, low fiber count cables with limited unsupported span lengths, which can be installed aerially, underground or buried. As it is used in outdoor, drop cable shall have a minimum pull strength of 1335 Newtons according to the industry standard. Fiber optic drop cables are available in many different types. The three most commonly used fiber drop cables include flat drop cable, figure-8 aerial drop cable and round drop cable.

 

Outdoor Fiber Drop Cable

Outdoor Fiber Drop Cable, with a flat out-looking, usually consists of a polyethylene jacket, several fibers and two dielectric strength members to give high crush resistance. Fiber drop cable usually contains one or two fibers, however, drop cables with fiber counts up to 12 or more are also available now. The following picture shows the Outdoor Fiber Drop Cable.

Indoor Fiber Drop Cable

Indoor Fiber Drop Cable, with a flat out-looking, usually consists of a polyethylene jacket, several fibers and two dielectric strength members to give high crush resistance. Fiber drop cable usually contains one or two fibers, however, drop cables with fiber counts up to 12 or more are also available now. The following picture shows the Indoor Fiber Drop Cable.

Figure-8 Aerial Drop Cable

Figure-8 aerial drop cable is self-supporting cable, with the cable fixed to a steel wire, designed for easy and economical aerial installation for outdoor applications. This type of fiber drop cable is fixed to a steel wire as showed in the following picture. Typical fiber counts of figure-8 drop cable are 2 to 48. Tensile load is typically 6000 Newtons.
