Îà2ÊÏ * 4 – 20
ÒÓ Ó 31.3-00214534-036-2004
Fiber optic module-core cables, double-layer galvanized steel-wire armoured, sealed with alumopolymer tape, with polyethylene outer sheath
Mark formation:
Îà2ÊÏ-[a]-[b] [c]4([d]x[e]+[f])-20
[a] central strength element
• C – steel
• No marks – dielectric
[b] quantity of optical fibers in the cable, possible values
• 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 30, 32, 52, 56, 60, 64
[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 ... 4 – 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 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
Order placing: sample of indication (corresponds to configuration pattern)
Îà2ÊÏ-10A4(2x4+1x2)-20 • ÒÓ Ó 31.3-00214534-036-2004
Cables are used for:
• laying in soils of all categories, areas with soils subjected to cryosolic distortions
• laying on the bottom of navigable rivers and deep water canals (depth up to 100 m)
