Optical Communication Cable TO2 (OV types E3) for Underground Installation in Challenging Conditions

Fibre-optic cable for laying in the ground, in areas with active manifestations of permafrost ground processes, navigable rivers and deep water obstacles, as well as on bridges and trestles. Cables can contain standard optical fibres (OV E3 (G652D) / E3 (G652D)200 / E3 (G657A1/G652D) / E3 (G657A1/G652D) ALPHA / E3 (G657A1/G652D)200 / E2 (G654E), manufactured according to TU 27.31.12-004-99992751-2017 or TU 636570-002- 99992751-2016). OMs manufactured in the territory of the Eurasian Economic Union member states are used.

Attenuation coefficient at the working wavelength, dB/km: for ?=1310nm not more than 0.35; for ?=1550nm not more than 0.22. Operating temperature of the cable is from -50º? to +70º?.
