Item Test Method Requirements
Tensile performance IEC 60794-1-2-E1 The maximum increase in attenuation less Load: Maximum allowed tensile than 0.1dB, and fiber strain less than 0.6%According to 2.4 under short load. Cable length under tension: Not less No change in attenuation after test at 1550nm. than 50m. Under visual examination without Duration of load sustain: 1min. magnification, no damage to the sheath or to Velocity of transfer device: the cable elements after test. 10mm/min
Crush Under short term load, there shall be less than 0.1dB in attenuation at 1550 nm after the test. IEC 60794-1-21-E3 Under visual examination without Load and Duration: According to 2.4 magnification, no damage to the sheath or to Number of tests: 3 the cable elements. The imprint of the striking Spacing between test places: 500 mm surface on the sheath is not considered mechanical damage.
Flame retardant IEC 60332-1-2
Water Penetration Fiber optic cables do not have water blocking requirements.
Remark: “No attenuation changes” is considered as the attenuation changes ≤ 0.05 dB.
