Purchase informations

The cable is sold in sections of 1000 meters! There is no rewinding possibility

Opton S-QOTKSdD is a universal drop-fiber cable for indoor and outdoor use. The outer shell (thickness about 0.7 mm) is made of polyurethane, it is resistant to UV radiation and the negative weather conditions effect. The offered product is equipped with 4 G.657.A2 fibers covered with multicolored varnish (without tubes). The 657.A2 fiber is distinguished by a better flexibility than the 652.D, which is why it can also be successfully used inside residential buildings in places where the cable needs to be run, for example along the wall. The optical fiber is distinguished by its small outside diameter - 2.9 mm and weight - about 8.2 kg / km.

The cable has been reinforced with a large amount of aramid fibers (9 den), the maximum tension force (momentary / installation) is 800 N.The  S-QOTK is completely dielectric, it can be successfully used in overhead installations and telecommunication ducts. Perfect as a main route, eg in PON network locations, where there are relatively few subscribers and no more than 4 fibers are needed. The cable is supplied on a plastic roll that allows convenient unwinding.

The maximum span: in the Polish conditions marked as NESC Heavy (due to icing and low temperatures), the maximum span is 30 meters! Correspondingly for lighter climatic conditions, the span is: NESC Medium: 56 meters, NESC Light: 112 meters.

The cable is sold on a roll of 1000 meters (1 km)!
