PM FWDM Device Polarization Maintaining Filter WDM 1290 1500nm Pass 1524 1650nm Block Low Loss High Isolation For ROADM CATV CWDM PON
PM FWDM Device (PM Filtered WDM Device) is a filter device designed specifically for polarization-maintaining fiber systems, with a transmission range of 1290~1500nm and a cutoff range of 1524~1650nm, used for precisely separating or combining different wavelength signals within the same fiber.
Low Insertion Loss, Minimal Link Budget Pressure
Transmission channel IL ≤1.0dB. In multi-stage amplification or long-distance transmission scenarios, the impact on overall network power budget and OSNR is smaller, allowing for more system margin.
High Isolation, Strong Crosstalk Suppression
Transmission channel isolation ≥30dB, effectively suppressing interference from other wavelength bands such as 1524–1650nm to the main service wavelength, enhancing system stability and reliability.
Good Polarization and Reflection Performance
Minimum extinction ratio not less than 18dB (the datasheet lower limit is “≤18dB"; in practice, it can be considered a high extinction ratio level), return loss ≥50dB, suitable for polarization-sensitive systems, helping improve the signal-to-noise ratio in interference and coherent applications.
Wide Operating Wavelength and Temperature Range
The device supports a wide wavelength range of 1260–1620nm, operating temperature 0–70℃, storage temperature -40–85℃, suitable for various environments including indoor equipment rooms and outdoor cabinets.
Compact Packaging, Easy Integration
Adopts φ5.5*L38mm steel tube packaging, with a compact structure, easy to install in modules, box-type devices, or 1U/2U racks, facilitating high port density designs.
Standards Compliance, High Engineering Reliability
Complies with ITU-T G.694.2 and RoHS standards, capable of long-term online operation, suitable for carrier-grade network applications.
