Multi Loose Tube Optical Fiber Cable

A steel wire locates in the center of core as a metallic strength member.

Multi loose tube optical fiber cable.

Tubes and fillers are stranded around the strength member into a compact and circular cable core. Their designs utilize 250µm fibers in both central multi loose tube constructions ranging in fiber counts from 2 to 288. Since the tube does not have direct contact with the fiber any cable material expansion or contraction will not cause stress on the fiber. But there are two basic styles of fiber optic cable construction.

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. Each however is designed for very different environments. The tubes are filled with a water resistant filling compound. Download datasheet product updated on april 15th 2020.

Multi loose tube fiber optic cable cpr. 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. Loose tube and tight buffered. 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.

From the picture below we can see that loose tube fiber holds more than one optical fiber each individually. Multi loose tube fibre optic cable is typically used in building backbone application networks in high risk harsh environments with high fibre counts. Multi loose tube fibre optic cable is available in a 8 912 250µm fibres within gel filled tubes and water blocking glass yarns. 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.

Tight buffered and loose tube fiber are the two styles of constructions fiber optic cables offered. Mgtsv fiber optic cable the fibers 200μm or 250μm are positioned in a loose tube made of a high modulus plastic. 45 75 89 22 99 mon fri. Loose tube fiber and tight buffered fiber.

Both contain a type of strengthening member such as aramid yarn stainless steel wire strands or gel filled sleeves. Fiber optic cables for fttx projects single multi loose tube micro fiber optic cables with single mode optical fiber g 657a g 652d.
