A look at the construction of the cable

Key features:

• for indoor and outdoor applications
• FireBur LSZH jacket
• UV resistant
• max. pulling force 2000 N
• gel-filled central tube
• reinforced with aramid yarn for anti-rodent protection
• a ripcord for easy removal of the sheath
• convenient processing
• CPR class: Eca

DRAKA U-DQ(ZN)BH 12E is a universal fiber-optic cable for indoor and outdoor applications. Single-mode G.657A1 9/125 μm fibers are contained in a central gel-filled tube. The gel in the tube is a kind of protective coating for optical fibers, which absorbs mechanical stresses and protects against environmental factors. The aramid yarn is designed to protect the central tube and fibers from mechanical damage, including risks posed by rodents.

DRAKA U-DQ(ZN)BH 12E contains 12 single-mode fibers (Sumitomo). The color identification of the buffer layers complies with the TIA-EIA-598-A standard. The jacket (sheath) is made of low smoke zero halogen flame retardant polyolefin (LSZH).

Universal cables are gel-filled fiber-optic cables intended for horizontal connections inside and outside buildings. Due to their small size and flexibility, the cables are ideal for installation in cable ducts. They are used in modern FTTH and FTTB systems, in server rooms, and in between buildings. Unlike outdoor cables, universal cables can also be used inside buildings. This eliminates the need to create additional transitions, splices and cable distribution frames at the junction of the external and internal networks. Universal cables can be laid in cable ducts or even directly in trenches in the ground (in places where they are not exposed to direct mechanical damage).
