■ Optical Characteristics:

Attenuation:

G.652.D Fiber:

1. 

1. @ 1310 nm: ≤ 0.36 dB/km

2. @ 1550 nm: ≤ 0.22 dB/km

3. Application: This fiber offers low attenuation at both 1310 nm and 1550 nm, making it ideal for long-distance communications.

G.655 Fiber:

1. @ 1310 nm: ≤ 0.40 dB/km

2. @ 1550 nm: ≤ 0.23 dB/km

3. Application: This fiber also provides excellent attenuation performance, although slightly higher than G.652.D at 1310 nm, making it suitable for applications with advanced dispersion management needs.

50/125 µm (Multimode):

1. @ 850 nm: ≤ 3.0 dB/km

2. @ 1300 nm: ≤ 1.0 dB/km

3. Application: Multimode fiber that operates at higher attenuation values but is commonly used for short-distance applications like within buildings or campuses.

62.5/125 µm (Multimode):

1. @ 850 nm: ≤ 3.0 dB/km

2. @ 1300 nm: ≤ 1.0 dB/km

3. Application: Similar to 50/125 µm multimode fiber, used for short-distance transmission with slightly larger core size.

Bandwidth:

50/125 µm (Multimode):

1. @ 850 nm: ≥ 500 MHz·km

2. @ 1300 nm: ≥ 1000 MHz·km

3. Application: Higher bandwidth at 850 nm and 1300 nm ensures that the fiber can support high-speed data transmission over relatively short distances.

62.5/125 µm (Multimode):

1. @ 850 nm: ≥ 200 MHz·km

2. @ 1300 nm: ≥ 600 MHz·km

3. Application: Slightly lower bandwidth than 50/125 µm, but still suitable for multimode applications with moderate data transmission needs.

Polarization Mode Dispersion (PMD):

G.652.D Fiber:

1. Individual fiber: ≤ 0.20 ps/√km

2. Design link value (M=20, Q=0.01%): ≤ 0.1 ps/√km

3. Application: Low PMD ensures minimal signal distortion, ideal for long-distance communication at high speeds.

G.655 Fiber:

1. Individual fiber: ≤ 0.20 ps/√km

2. Design link value (M=20, Q=0.01%): ≤ 0.1 ps/√km

3. Application: Similar to G.652.D, G.655 fiber also offers low PMD, ensuring high performance for long-distance and high-speed data transmission.
