Product Description

Reliable PM DWDM for Enhanced Signal Quality

Product Description

PM DWDM stands for Polarization-Maintaining Dense Wavelength Division Multiplexing. It is a technology used in optical fiber communication systems that combines multiple signals, each at a different wavelength, into a single optical fiber.

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.

Features

• High lsolation
• High Return Loss
• Low Insertion Loss
• High stability and reliability

Applications

• CATV router
• GPON network
• DWDM system
