• No marks – dielectric |
[b] quantity of optical fibers in the cable, possible values |
• 10, 16, 18, 20, 26, 28, 30, 32, 36, 40, 65, 70, 75, 80 |
[c] type of optical fiber |
• E – single-mode (ITU-T G.652B) |
• A – single-mode with extended wavelength band (ITU-T G.652D, ITU-T G.657A1) |
• C – single-mode with non-zero shifted dispersion (ITU-T G.655) |
• M – multimode with core and sheath diameter ratio 50 : 125 mm (ITU-T G.651) |
• B – multimode with core and sheath diameter ratio 62.5 : 125 mm (IEC 60793-2) |
[d] 3 ... 5 – number of optical modules in cable |
[e] quantity of optical fibers in the module: |

|
Manufacturing of cables with two copper insulated remote power conductors instead of two string fillers is possible |
Manufacturing of cables in climate version F is possible |
Manufacturing of cables with steel strength element is possible |
Manufacturing of cables with polyethylene intermediate sheath between armour layers is possible |
It is possible to manufacture cables with gel-filled core or dry core (with water-blocking yarns and tapes) |
It is possible to manufacture cables with a number of core elements up to and including 18 |
