Prysmian group, now including the Draka, offers 1728 fiber cable in loose tube ribbon construction. The cable is branded as MassLink 1728. Loose tube Ribbon construction combines good attributes of both loose tube and the ribbons. Prysmian prefer to call it Ribbon stranded tube cable. Company’s product catalog says, 1728 fiber cable is the highest fiber count cable available with them. High fiber count cables maximize duct utilization in critical installations such as bridge crossings.
Prysmian’s 1728 fiber cable is ideal for connecting large fiber distribution hubs. The cable offers easy handling as it is lighter in weight compared to multiple number of cables in case the installer use lower fiber count cables. MassLink 1728 cable is designed with ribbonized fibers. Both 12 and 24 fiber ribbons are easy to mass strip during installation. Ribbonized fibers also allow mass fusion splicing. Ribbons can be easily split from 24 fiber matrix to two individual 12 fiber ribbon units. This enables the use of industrially available mass fusion splicing machines during installation.
Mass fusion splicing saves a lot of Ribbonized fibers can also be split into individual fibers quickly and cleanly. This allows splicing of individual fibers with that of an interconnecting loose tube cable with individual fibers. Ribbon mass fusion splicing saves a lot of money and time to the favor of project owner.
MassLink 1728 brand cables are available in rodent resistant version as well. Rodent resistance is best achieved by applying a layer of steel tape, usually corrugated, which is then known as an armor to the cable from rodents. This layer increases the cable’s resistance to the mechanical stresses. Prysmian use dry water-blocking technology, which permits quick cable preparation and termination as water-blocking materials can be easily removed from the cable core. Multiple loose buffer tubes are stranded using the reverse oscillation technique. MassLink 1728 cable is uniformly flexible in all directions to simplify access, handling and management of fibers and ribbons. Termination is made easier with a fewer number of ribbons in each buffer tube.
The cables are manufactured in Prysmian’s manufacturing locations in U.S and Canada. Cable comply with RDUP (RUS) listed in accordance with PE-90, 7CFR 1775.900. Cable can meet a dynamic bend requirement of 20 times the cable diameter and a static bend requirement of 10 times the cable diameter. During installation, the cable can be pulled with a maximum tensile strength of 4500N, which is equivalent of 1000 lbf. Residual tensile strength, that is, after installation, the cable design allows 800N, which is equivalent of 180 lbf. Crush resistance of 220N/cm (125 lbf/inch) can be applied to the cable for short term, while the long term crush resistance shall be 110N/cm (63 lbf/inch). MassLink 1728 cable can be installed at a temperature as low as -30 degree C. Maximum installation temperature can be +70 degree C. The cable allows operation in a wide range of temperature with a minimum of -40 deg C and a maximum of +70 degree C. Cable shall be stored or shipped at temperature that varies from -40 degree C to +75 degree C.
MassLink 1728 cables are available in All-dielectric design and Single Armor/Single-Jacket design. 432 fibers are put into a buffer tube in both cable designs. So, there will be 4 buffer tubes. The buffer tube outer diameter is around 12.1 mm (millimeters), which is around 0.476 inches. All-dielectric cable has an outer diameter of 31.5 mm, while the armor cable diameter is 35.1 mm. Armor cable is heavier than All-dielectric cable. The weight of All-dielectric cable is 749 kg/km, while the weight of armor cable is 965 kg/km. Maximum reel length is 3,020 meters for the All-dielectric cable, while the maximum reel length of armor cable is 2,170 meters.
