OPTICAL FIBRE CABLES
"BREAK-OUT" optical fibre
For indoors/outdoors installation
Optical fibre cables for data transmission OM1 OM2 OM3 OS1 (multimode and singlemode)
▼ DESCRIPTION
"Break-out" type cables are multi-tight cables suited for indoors installation and are available according to colour standards with 900 mi-
cron coloured fibre sheaths. Each structure is like a single-unit tight cable, composed of a central single bundle of fibre strands surrounded
by glass fibres to give it traction resistance and resistance against attack by rodents. This is bundled with other structures around a filler to
create the break-out or multi-tight structure. The whole assembly is enclosed in a black jacket for outdoors installation. The jacket has LSZH
(low smoke zero halogen) fire specification and complies with IEC standards regarding flame and fire performance. The optical fibres are
available in all four standard homologated versions: MultiMode OM1, OM2, OM3, and SingleMode OS1.
▼ CHARACTERISTICS ▼ APPLICATION
• Coloured fibres for quick identification • Suited for laying in indoors ducting
• Rip cord for quick stripping • Suited for use in campus backbones, building backbones and horizontal cabling
• Black LSZH jacket for indoors and outdoors installation • Suited for high density sites and fusion splicing
• Compact design for installation in restricted space. • Compact structure, suited for installation in limited areas such as duct pipes.
