M FWDM Device | Polarization Maintaining Filter WDM, 1480/1550nm, Low Insertion Loss, High Isolation
The PM FWDM Device is a polarization-maintaining (PM) filter-type 1480/1550nm WDM combiner/splitter designed specifically for PM fiber systems. It enables efficient combining or splitting of 1480nm pump light and 1550nm signal light within the same fiber. The device uses a filter-type structure with Corning PM15-U25D panda polarization-maintaining fiber, has a transmission wavelength range of 1535–1565 nm (Pass/Transmission) and a reflection wavelength of 1480±10 nm (Reflection). It can achieve low-loss and high-isolation channel management in C-band EDFA, amplification links, and ROADM/CATV systems. Typical transmission insertion loss is ≤0.8 dB, reflection end insertion loss is ≤0.6 dB, return loss is ≥50 dB, and it maintains good operational adaptability and environmental stability across a wide wavelength range of 1260–1620 nm.
Transmission end IL ≤0.8 dB, reflection end IL ≤0.6 dB, minimizing the impact on system OSNR and power budget.
Transmission isolation ≥25 dB, reflection isolation ≥15 dB, effectively isolating 1480/1550nm signals from noise and improving system stability.
Uses Corning PM15-U25D PM fiber, compatible with PM amplifiers and PM patch cords, providing clear and controllable polarization direction.
Supports 1260–1620 nm broadband applications, operating temperature 0–70 ℃, storage temperature -40–85 ℃, suitable for indoor equipment rooms and most engineering environments.
Complies with ITU-T G.694.2 and RoHS standards, ensuring long-term operational reliability, suitable for carrier-grade system deployment.
