A Detailed Comparison of G.652 and G.655 Single-Mode Fibers
Jun 07, 2024
G.652 and G.655 are both single-mode fibers, but they differ in their characteristics and applications. G.652 fiber is one of the earliest developed single-mode fibers and offers good transmission performance at a lower cost, making it widely used in short-haul and intermediate-haul communication systems. G.655 fiber is an improved single-mode fiber with lower dispersion and polarization mode dispersion, making it more suitable for long-haul and high-bandwidth communication systems.
| G.652 | G.655 | |
|---|---|---|
| Single-mode | Single-mode | |
| 9μm | 9μm | |
| 125μm | 125μm | |
| 0.14 | 0.14 | |
| 10.5μm | 10.5μm | |
| 1310nm | 1310nm | |
| Dispersion (1310nm) | < 9.5 D/km | < 2.0 D/km |
| Dispersion (1550nm) | < 17 D/km | < 3.2 D/km |
| Polarization Mode Dispersion (1550nm) | < 0.2 ps/km | < 0.05 ps/km |
| Attenuation (1310nm) | < 0.35 dB/km | < 0.35 dB/km |
| Attenuation (1550nm) | < 0.22 dB/km | < 0.22 dB/km |
| 85 degree | 85 degree | |
| -40 degree | -40 degree | |
| Short-haul and intermediate-haul communication systems | Long-haul and high-bandwidth communication systems |
G.652 and G.655 single-mode fibers each have their own advantages and disadvantages. G.652 fiber offers good transmission performance at a lower cost, making it suitable for short-haul and intermediate-haul communication systems. G.655 fiber features lower dispersion and PMD, making it more appropriate for long-haul and high-bandwidth communication systems.
The choice of single-mode fiber type should be based on specific application requirements.
