Micromodules are used in loose tube cable construction, demanded by the duct condition where there are very less space available. A micromodule is made with thin wall tubing, filled with a suitable compound, housing a bundle of optical fibres.
Alternatively micromodules can be manufactured by replacing the central strength member with radial strength, in which case it is known as “Modified Micromodule Cable design”. In such designs, the compression of the micromodules against the central strength member is eliminated and easy access is enabled to both the micromodule tubes and the fibres.
Such a cable design results in one of the smallest cable cross sections in the industry, offering increased protecting during sheath entry, and is resistant to crush and impact forces.
The small diameter micromodule is made of a very soft and flexible material which is easily strippable without dedicated tool. Furthermore this leads to easy micromodules storage in splicing boxes and trays. Suitable for various applications, micromodule cables offer significant improvement in installation and deployment time over other cable type. Thanks to its attributes, “micromodule cables” is a suitable design for FTTH applications.
