■ Optical Characteristics:
Attenuation:
G.652.D Fiber:
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.
