Inner diameter of optical cable plastic tube
A 144 fiber loose tube cable is typically 15-16mm diameter while a comparable micro cable is only about 8 mm diameter - half the size and about one-third the weight. The smaller size allows for much larger fiber counts, over 3,000 fibers in some designs. If multiple cables are being pulled into one innerduct, the sum of the outer diameters of each cable is divided by the innerduct interior diameter. A variety of wall strengths are available including Types 11 and 9, Schedules 40 & 80, SDR's 17, 13. 9 in (177 mm) Minimum Working Bend Radius = 6. 7 cm) To find the minimum diameter requirement for pull wheels or.
