■ Mechanical Characteristics:

Proof Stress Level:

Additional Attenuation with Bending:

· For 10 turns with D=30mm:

o At 1550 nm: α ≤ 0.25 dB

o At 1625 nm: α ≤ 1.0 dB

· For 1 turn with D=20mm:

o At 1550 nm: α ≤ 0.75 dB

o At 1625 nm: α ≤ 1.5 dB

o These values represent the additional signal loss (attenuation) induced when the fiber is bent. A smaller bending radius or more turns results in higher attenuation.
