Characteristics

The information you've provided includes details about fiber optic cables and their various performance specifications. Here's a breakdown of the key characteristics:

Fiber Types and Specifications:

1. G.652.D and G.655 are types of single-mode fiber with specific attenuation and dispersion characteristics, which are often used in various optical transmission systems.

   • G.652.D is a standard single-mode fiber with lower attenuation, suitable for most general applications.
   • G.655 is a non-zero dispersion-shifted fiber designed for long-haul, high-capacity transmission, especially where dispersion compensation is needed.

2. Multimode Fibers:

   • 50/125 µm and 62.5/125 µm are the core/cladding diameters for multimode fibers, commonly used for short-distance data transmission (e.g., within buildings or campus environments).

Attenuation (Signal Loss):

• G.652.D and G.655:

  • At 850 nm and 1300 nm, both types of fibers have an attenuation of ≤3.0 dB/km.
  • At 1310 nm, G.652.D has an attenuation of ≤0.36 dB/km, and G.655 has ≤0.40 dB/km.
  • At 1550 nm, the attenuation is ≤0.22 dB/km for G.652.D and ≤0.23 dB/km for G.655.

• Multimode Fibers (50/125 µm and 62.5/125 µm):

  • At 850 nm, attenuation is ≤3.0 dB/km.
  • At 1300 nm, attenuation is also ≤1.0 dB/km.

Bandwidth (Signal Transmission Capacity):

• Multimode fibers:
  • At 850 nm, 50/125 µm fiber has a bandwidth of ≥500 MHz·km, while 62.5/125 µm fiber has ≥200 MHz·km.
  • At 1300 nm, 50/125 µm fiber has a bandwidth of ≥1000 MHz·km, while 62.5/125 µm fiber has ≥600 MHz·km.

Polarization Mode Dispersion (PMD):

• Individual Fiber: Both G.652.D and G.655 fibers have a polarization mode dispersion value of ≤0.20 ps/√km.
• Design Link Value (M=20, Q=0.01%): Both G.652.D and G.655 fibers have a design link value of ≤0.1 ps/√km.
