From the picture below we can see that loose tube fiber holds more than one optical fiber each individually.
Central loose tube cable.
Loose tube cores are best suited for armored.
The optical performance is virtually unchanged as the cable is exposed to the elements.
Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber.
Pe is the preferred option in outdoor environment for water.

The first is plastic and the other waterproof acrylate.
Aramid yarn or fi ber glass is wound around the tube to provide physical protection and tensile strength.
This cable has been designed for lans and other low fiber count applications.
But there are two basic styles of fiber optic cable construction.
It is based on central loose tube catv construction.
With options for standard non armour corrugated steel or steel wire armours for protection.
The loose tube design isolates the fibers from outside environmental and mechanical stresses.
Our range includes fibre counts from 2f up to 24f in om1 om2 om3 om4 os1 2 fibre types.
Rather than using the gel layer loose tube has tight buffered cables have a two layer coating.
Webro s range of central loose tube fibre optic cables are suitable for use on backbone networks.
Telcordia technologies bicsi rus rural utility service and the telco and cable tv markets support this design.
Gyxtw metal strength member central loose tube aluminum tape shielding with4 parallel steel wries in black pe sheath outdoor optical cable applications this product can be used as outdoor transmission lines in core network for example long haul and relay lines between local telecommunication centers.
The design caters the protection of the fibers through thixotropic jelly filled in the tube the moisture barrier is the water swellable tape and the strength members are phosphorus coated steel wires with outer jacket of high density polyethylene.
Fiber optic cable is available in many physical variations such as single and multiple conductor constructions aerial and direct burial styles plenum and riser cables etc.
Loose tube fiber and tight buffered fiber.
Central loose tube cables in loose tube cables the coated fiber floats within a rugged abrasion resistant oversized tube which is filled with optical gel.
Fiber loose tube cable belden s loose tube cables are ideal for both outdoor indoor outdoor applications including use in conduit direct burial lashed aerial trunking.
Central loose tube cable contains one tube with 2 24 fi bers which is fi lled with water blocking gel.
Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288.
