Central Loose Tube Cable

Rather than using the gel layer loose tube has tight buffered cables have a two layer coating.

Central loose tube cable.

Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber. Aramid yarn or fi ber glass is wound around the tube to provide physical protection and tensile strength. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288. This cable has been designed for lans and other low fiber count applications.

Pe is the preferred option in outdoor environment for water. 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. Our range includes fibre counts from 2f up to 24f in om1 om2 om3 om4 os1 2 fibre types. Central loose tube fibre optic cable.

Webro s range of central loose tube fibre optic cables are suitable for use on backbone networks. 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. Telcordia technologies bicsi rus rural utility service and the telco and cable tv markets support this design.

The loose tube design isolates the fibers from outside environmental and mechanical stresses. 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 optical performance is virtually unchanged as the cable is exposed to the elements. From the picture below we can see that loose tube fiber holds more than one optical fiber each individually.

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. The first is plastic and the other waterproof acrylate. 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. It is based on central loose tube catv construction.

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. 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. But there are two basic styles of fiber optic cable construction.
