Rather than using the gel layer loose tube has tight buffered cables have a two layer coating.
Central loose tube cable.
From the picture below we can see that loose tube fiber holds more than one optical fiber each individually.
The optical performance is virtually unchanged as the cable is exposed to the elements.
It is based on central loose tube catv construction.
Being more robust than loose tube cables they are best suited for moderate length lan or wan connections long indoor runs direct burial and for underwater use.
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.
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.
But there are two basic styles of fiber optic cable construction.
Webro s range of central loose tube fibre optic cables are suitable for use on backbone networks.
This cable has been designed for lans and other low fiber count applications.
The loose tube design isolates the fibers from outside environmental and mechanical stresses.
The first is plastic and the other waterproof acrylate.
Cable can be jacketed with either pe or lszh.
With options for standard non armour corrugated steel or steel wire armours for protection.
Central loose tube cable contains one tube with 2 24 fi bers which is fi lled with water blocking gel.
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.
Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber.
Central loose tube fibre optic cable.
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.
Loose tube fiber and tight buffered fiber.
Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288.
Aramid yarn or fi ber glass is wound around the tube to provide physical protection and tensile strength.
Pe is the preferred option in outdoor environment for water.
Breakout cable 6 central loose tube cable 517 ftth mini loose tube cable 6 fith cable 16 flat self supporting lt cable 6 heavyduplex fig 0 cable.
Loose tube cores are best suited for armored.
