Optical communication cable TO1 (OV types E3 (G652D, E3 (G657A1/G652D), E2 (G654E)) optical fibre manufacturer AO Optikovolokon

Fibre-optic cable for laying in the ground, in cable ducts, including swamps and shallow, non-waterable rivers, in cable ducts, in conditions of moisture exposure, as well as on bridges and trestles. Laying in soils subject to permafrost deformations is allowed if the cable resistance to DDDN is not less than 20 kN
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. Cable operation temperature is from -50º? to +70º?.
