Optical Communication Cable DAS E3 for Ground Installation and Environmental Resistance

Fibre-optic cable for laying in the ground and in cable ducts, in the presence of high requirements for mechanical stability, in conditions of exposure to moisture, including swamps and shallow, non-flowing rivers, as well as on bridges and overpasses Cables may 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?.
