1. Polarization Maintenance:
- PM DWDM employs polarization-maintaining fibers, which preserve the polarization state of the transmitted light. This characteristic is crucial for maintaining signal integrity, especially in high-performance applications or long-distance transmission, where polarization-dependent losses can degrade the signal quality.
2. Dense Wavelength Division Multiplexing (DWDM):
- DWDM technology enables the transmission of multiple data channels over a single optical fiber by using closely spaced wavelengths (or channels) in the optical spectrum. This allows for a significant increase in bandwidth and capacity without the need for additional fibers. DWDM systems can typically handle dozens to hundreds of channels, each at different wavelengths, effectively maximizing the capacity of the existing infrastructure.
