NOTES:
Bend Radius:
*These radius values relate only to the physical cable performance, not to recommended blowing
radii. See Installation manual for blowing advice.
Force:
** These products are normally buried, not pulled, but pulling is acceptable. After applying pulling
tensions, allow time for the pulled product to relax. See Installation manual.
Note 1: Diameters and thicknesses are measured to the nearest 0.1mm.
Note 2: ‘nominal’ data is based on middle-spec, and is for information only, not for inspection purposes.
Note 3: Sketches are for information purposes only, and should not be used for inspection.
Note 4: When interpreting performance data and installing m/ds, bundles, or fibre units, it is
assumed that the user has been trained by Emtelle.
Note 5: All data is believed to be accurate but
Note 6: Users must establish the suitability of these products for their own applications.
