Fiber optic overhead module-core cables, with polyethylene outer sheath
Mark formation:
ÎÏÒ-[a]-[b] [c]6([d]x[e]+[f])-8
[a] central strength element
• C – steel
• No marks – dielectric
[b] quantity of optical fibers in the cable, possible values
• 4, 6, 8, 10, 12, 16, 18, 20, 22, 24, 28, 30, 32, 36, 40, 48, 60, 72, 78, 84, 90, 96
[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] 1 ... 6 – number of optical modules in cable
[e] quantity of optical fibers in the module:
• 1 ... 16
(f) quantity of insulated copper conductors in cable
Optical modules are completed with string fillers up to total number of core elements
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 armouring (aramid yarns and/or corrugated steel tape) is possible
Manufacturing of cables with steel or dielectric wire rope (glass fiber rod) is possible
Manufacturing of cables with flame-retardant polymer compound outer sheath 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
Order placing: sample of indication (corresponds to configuration pattern)
