Optical Fiber Cable OGD for Ground Installation and Infrastructure Use

Fibre-optic cable for laying in soils of all categories (except for those subject to permafrost deformations), cable ducting, on bridges and trestles; for cable with armoured coating of dielectric rods - suspension on transmission line towers, contact network of electrified railways, including conditions of cable laying under increased requirements for resistance to external electromagnetic effects. The cable contains from 2 to 288 single-mode standard optical fibres (fibre type OV E3 (G657A1/G652d), manufactured according to TU 27.31.12-004-99992751-2017 or E3 (G652d) fibres manufactured according to TU 636570-002-99992751-2016), The production uses fibres manufactured in the territory of the member states of the Eurasian Economic Union. Attenuation coefficient at the working wavelength, dB/km: for ?=1310nm not more than 0,35; for?

=1550nm not more than 0,22. Cable operation temperature from minus 40 C to 60 C Permissible tensile force not less than 2.5 kN (indicated in the mark from 2.5 to 20 kN). To...
