Flexible Fiber-Optic Trailing Cable 6XV1820-6****

The flexible fiber-optic trailing cable contains two multimode graded fibers 62.5/125

∝m. Integrated dummy elements produce a round cross-section.

The outer jacket is labeled “SIEMENS SIMATIC NET FLEXIBLE FIBER OPTIC 6XV1 820-6AH10” at intervals of approximately 50 cm. Meter markers consisting of a vertical line and a 4-figure number make it easier to estimate the length of an installed cable.

Properties

The flexible fiber-optic trailing cable has the following properties:

SHighly flexible (100,000 bending cycles at a minimum bending radius of 150 mm)

SNot halogen free

SAvailable in meter lengths for up to 2000 m

SAvailable preassembled with 4 BFOC connectors in fixed lengths up to 650 m
