Optical Communication Cable DA2 for Ground Installation in Challenging Conditions

Fibre optic cable for laying into the ground, in areas with active manifestations of permafrost-soil processes, navigable rivers and deep water obstacles, as well as over bridges and overpasses. 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?.
