 FAQ

1: What is the difference between this product and a regular DWDM Mux/Demux?

A: This product is a Polarization Maintaining PM DWDM Device, suitable for link or device integration scenarios with higher polarization stability requirements. Compared to regular DWDM devices, the PM structure is more suitable for polarization-sensitive systems, test platforms, coherent communication links, or high-stability optical modules. The product page clearly positions it as a PM DWDM Device / DWDM Multiplexer Demultiplexer.

2: What are the key fiber parameters of this product?

A: The product page indicates that its coating diameter is 245 µm, cladding diameter is 125 µm, core diameter is 3.0 µm, and attenuation is ≤0.5 dB/km. These parameters help engineers assess its compatibility with existing PM fiber links, test fixtures, and packaging structures.
