Flexible Fiber-Optic Trailing Cable 6XV1820-6****
The flexible fiber-optic trailing cable contains two multimode graded fibers 62.5/125
µm. Integrated blind elements produce a round cross-section.
The outer sheath 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:
S Highly flexible (100,000 bending cycles at a minimum bend radius of 150 mm)
S Not halogen free
S Available in meter lengths for up to 2000 m
S Available preassembled with 4 BFOC connectors in fixed lengths up to 650 m
