* - The stringing tension is always measured at the tensioner side. In general the maximum stringing
tension should be approximately half of the maximum sagging tension and should never exceed
20% RBS of the OPT-GW.
** - The value indicated is for the first and last structures of the pull and is based on 40 times the
diameter of the OPT-GW. Smaller diameters can be used at tangent structures. Reference AFL's
installation instructions for more details.
Reference AFL's "Recommended Installation Procedures for Composite Optical Ground Wire" for
detailed installation instructions.

Maximum lengths shown are the longest lengths that AFL offers. Longer lengths may be possible.
Ordered lengths should include a distribution of lengths, i.e., all reels cannot be ordered at the maximum.
A typical reel length distribution is as follows:
6000m – 7000m ~ 15% of reels
4500m – 6000m ~ 55% of reels
2500m – 4500m ~ 25% of reels
<2500m ~ 5% of reels
Wood reels with flex-wrap covering are standard. Non-returnable steel reels and/or wood lagging are
available upon request. Additional reel sizes may be available upon request.
Steel reels are recommended for long term storage. Reference AFL's "Fiber Optic Cable Receiving,
Handling and Storage" document for additional information.
