Fibre Optic Cable
Fibre optic cable transmits data as pulses of light rather than electrical signals, giving higher speed, bandwidth and reliability than copper for backbone links. Bownet stocks tight buffered, loose tube and armoured constructions across OM and OS categories.

Fibre optic cable carries data as pulses of light instead of electrical signals, giving higher bandwidth, longer reach and better immunity to interference than copper cable, which makes it a common choice for backbone and campus links. Bownet stocks tight buffered, loose tube and armoured constructions.
Choosing fibre optic cable
- Fibre category: OM1, OM3 and OM4 multimode for shorter high-bandwidth runs, or OS2 singlemode for long distance links.
- Cable type: tight buffered cable for internal patching, loose tube for outdoor runs, and steel tape or steel wire armoured builds for extra mechanical protection.
- Core count: from 4 core up to 48 core, sized to the number of fibre links the route needs to carry.

Fibre Optic Cable FAQs
What is the difference between tight buffered and loose tube fibre cable?
Tight buffered fibre cable has each fibre individually coated for easier internal patching, while loose tube fibre cable holds fibres in a gel filled tube, suited to outdoor and underground runs.
Should I choose OM multimode or OS2 singlemode fibre?
OM1, OM3 and OM4 multimode fibre suit shorter, high-bandwidth links such as within a building or campus, while OS2 singlemode fibre is used for longer distance backbone and external runs.
When do I need armoured fibre cable?
Steel tape and steel wire armoured fibre cable add mechanical protection for direct burial or exposed external routes, where a standard loose tube or tight buffered cable would be at risk of damage.
