Multi loose tube optical fiber cable.

Tubes and fillers are stranded around the strength member into a compact and circular cable core. Multi loose tube fibre optic cable is typically used in building backbone application networks in high risk harsh environments with high fibre counts. Tight buffered and loose tube fiber are the two styles of constructions fiber optic cables offered. Up to 72 fiber 6 element dry core om1 om2 om3 om4 multimode or g 657a1 g 655cd single mode 250µm multi loose tube mlt rodent resistant internal or external i e duct cables with e glass strength members and low smoke zero.

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. Fiber optic cables are constructed in two ways. Each however is designed for very different environments.

Multi 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. Loose tube and tight buffered. From the picture below we can see that loose tube fiber holds more than one optical fiber each individually.

A steel wire locates in the center of core as a metallic strength member. The tubes are filled with a water resistant filling compound. Between them there are several common denominators like the fact that both have in their interior a strengthening member of sorts that can be made of stainless steel in the form of wire strands aramid yarn or gel filled sleeves. Multi loose tube fibre optic cable is available in a 8 912 250µm fibres within gel filled tubes and water blocking glass yarns.

The multi loose tube cable construction consists of up to 144 250µm optical fibers in 12 fiber gel filled loose tubes with fillers where appropriate sz stranded around a fiber reinforced plastic frp central strength member with waterswellable threads and waterswellable tape. Mgtsv fiber optic cable the fibers 200μm or 250μm are positioned in a loose tube made of a high modulus plastic.
