Optical fibre cables for general applications
Description
Communication optical cables are produced according technical conditions TU 3587-023-24118545-2012 and intended for use in unified telecommunication network of Russian Federation.
Depending of type and performance, the cables can be deployed:
- underground including mechanized way;
- on river crossings, deep water reservoirs, in swamps;
- on bridges, overpasses in cable conduits, in blocks, in special tubes;
- on aerial lines, aerial contact lines of railway, on power poles;
- inside of buildings on walls in vertical and horizontal cable ways, in
tunnels and collectors, in subway tunnels.
Dependingconditionsofinstallation, the cables are operated by temperatures:
- suspended cables - from -60 °Ñ up to +70 °Ñ;
- cables installed on bridges, overpasses
- from -50°Ñ up to +50 °Ñ;
- underground and subsea cables - from -40 °Ñ up to +50 °Ñ.
The cables of
each type produced with different type and number of a cores and optical
fibres.
A standard notation of a special type of the cable contains twelve positions
which can be completed by other two (13 and 14).
A structure of notation of the cable should have:
