Over the past few years, several new technologies have made their way in the industry and revolutionized the same to great extent. One such evolution in the data communication technological landscape is air blown fiber.
ABF simply regarded as the use of compressed air or nitrogen to exactly blow lightweight optical fiber cables through a cable tube at up to 150 ft per minute. Standard blowing distances are 3300 ft for two to six fiber bundles and 1650 ft for 12 to 18 fiber bundles. However, if two sets of blowing equipment are used in conjunction, these distances can choose to be doubled. Whereas a tube cable is made of a flexible outer jacket containing separate flexible tubes, known as cells.
There are several advantage of using air blown fiber for installing fiber optic. The ABF cable design also reduces the need for slack boxes, typically required in conventional FO installations. This is because when you blow ABF, you can feasibly wind the slack inside the terminal cabinet’s fiber patch panel. If you wish to shift the enclosures, you can blow out the fiber, outspread the tube cable, and reinstall the fiber.
As these tubes are made of high-density polyethylene (HDPE) material, its coefficient of expansion is generally 10 times more than steel tube. Due to various complications and the intrinsic complexity of ABF systems, an ABF approved engineer should prepare the system design and supervise the installation.
