Multitube optical fibre
24/144 fibre Steel reinforced For outdoors or underground
installation
Data transmission optical fibre cables OM1 OM2 OM3 OS1 (multimode and singlemode)
▼ DESCRIPTION
Reinforced multitube cables are suited for outdoors and directly underground installation, with polyethylene jacket. The reinforcement
is composed of a corrugated steel tube waterproofed with a tape. The fibres are available according to colour standards, with 250 mi-
cron coloured sheaths. The fibres are contained in six PTB tubes, filled with GEL. Due to its construction, this cable has a high resist-
ance to impact and is very waterproof. The optical fibres are available in all four standard homologated versions: MultiMode OM1,
OM2, OM3, and SingleMode OS1.
▼ CHARACTERISTICS
• Coloured fibres for quick identification
• Rip cord for quick stripping
• PE jacket
• High mechanical strength
• High degree of waterproofing
▼ APPLICATION
• Black colour for outdoors or directly underground installation.
