Microducts
Microducts are small ducts for the installation of small microduct fibre optic cables. They have a size ranging from typically 3 to 16 mm and are installed as bundles in larger ducts. ==Description==
Microducts are typically small-diameter, flexible, or semi-flexible ducts designed to provide clean, continuous, low-friction paths for placing optical cables that have relatively low pulling tension limits. As stated in industry requirements document Telcordia (GR-3155, )〔(GR-3155-CORE, ''Generic Requirements for Microducts for Fiber Optic Cables,'' ) Telcordia.〕 ''Generic Requirements for Microducts for Fiber Optic Cables,'' microduct products are expected to: * Be compatible with existing construction designs and building configurations for both riser- and plenum-rated applications, including cable blowing apparatus. * Allow cables to be safely deployed through pull lines or strings using less than 50 lbs of force, and through cable blowing techniques at typical deployment speeds of 100-200 feet per minute.
