Optical fiber cable OS2 subscriber FTTx round SM 2J 9/125 G657A LSOH black, all-dielectric, 1000m ALANTEC FOK-W2J-SM-B-C-1

Universal fiber optic cable for FTTx networks

This OS2 fiber optic cable, designed for FTTx subscriber applications, combines versatility, durability, and ease of installation. It is an ideal solution for both professional installers and end customers looking for a reliable transmission medium. The cable delivers fiber optic signal directly to the home (FTTH) or office, providing fast and stable data transmission.

Construction and properties

The cable features a round construction reinforced with aramid fibers, making it self-supporting and resistant to tensile stress. The lightweight design with a diameter of 3 mm makes it easy to route the cable in various conditions – both indoors and outdoors. The G.657.A fibers used provide high flexibility and a minimal bending radius, which is particularly important during installation in tight spaces. The LSOH (Low Smoke Zero Halogen) jacket ensures fire safety by limiting the emission of toxic gases during combustion and is resistant to UV radiation, increasing the cable's durability in outdoor conditions. The fully dielectric construction eliminates the risk of electromagnetic interference.

Applications and benefits

The cable is designed for aerial installations and in telecommunication ducts using pneumatic (blowing) and mechanical (pulling) methods. Thanks to the high quality of workmanship and materials used, it ensures a reliable optical connection for a long time. Two single-mode (SM) fibers of the G.657.A standard guarantee high bandwidth and minimal signal loss. It meets the requirements of the Regulation of the Minister of Infrastructure, confirming its compliance with applicable safety standards. Euroclass Eca provides an appropriate level of fire safety in residential and commercial buildings. The cable is sold on spools of 1000 meters in length, which facilitates transport and assembly.
