FAQ
Q1: What is the PM Isolator WDM Hybrid Device (PM IWDM) primarily used for?
A: This product is mainly used in EDFA/Raman fiber amplifiers, polarization-maintaining fiber lasers, and high-end fiber optic instruments. It enables WDM wavelength division multiplexing/demultiplexing and optical isolation within a single device, suitable for the multiplexing, isolation, and transmission management of signal and pump light.
Q2: What wavelength combinations does this PM IWDM support?
A: This product supports various common signal and pump light combinations, including 1550/1480nm, 1550/1310nm, 1480/1550nm, and 1550/980nm, covering C-band signals and 1310nm, 1480nm, and 980nm pump configuration requirements.
Q3: What are the advantages of the PM IWDM compared to a "standalone isolator + standalone WDM" setup?
A: PM IWDM integrates a polarization-maintaining isolator and WDM in the same package, reducing fusion points and connection points, lowering cumulative insertion loss, simplifying module structure, and saving space. At the same time, it helps improve system polarization consistency, optical path stability, and long-term reliability.
