Central Loose Tube Cable

Telcordia technologies bicsi rus rural utility service and the telco and cable tv markets support this design.

Central loose tube cable.

The loose tube design isolates the fibers from outside environmental and mechanical stresses. It is based on central loose tube catv construction. This cable has been designed for lans and other low fiber count applications. Cable can be jacketed with either pe or lszh.

Pe is the preferred option in outdoor environment for water. 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.

Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber. 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. 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.

Aramid yarn or fi ber glass is wound around the tube to provide physical protection and tensile strength. 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. From the picture below we can see that loose tube fiber holds more than one optical fiber each individually.

The first is plastic and the other waterproof acrylate. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288. Loose tube cores are best suited for armored. Webro s range of central loose tube fibre optic cables are suitable for use on backbone networks.

With options for standard non armour corrugated steel or steel wire armours for protection. The optical performance is virtually unchanged as the cable is exposed to the elements. 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. 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.
