Description

M FWDM Device | Polarization Maintaining Filter WDM, 1480/1550nm, Low Insertion Loss, High Isolation

1. Product Overview

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.

2. Product Advantages
Low Insertion Loss, Reduced Link Budget Pressure

Transmission end IL ≤0.8 dB, reflection end IL ≤0.6 dB, minimizing the impact on system OSNR and power budget.

High Isolation, Effective Crosstalk Suppression

Transmission isolation ≥25 dB, reflection isolation ≥15 dB, effectively isolating 1480/1550nm signals from noise and improving system stability.

Polarization-Maintaining Design, Controllable Polarization State

Uses Corning PM15-U25D PM fiber, compatible with PM amplifiers and PM patch cords, providing clear and controllable polarization direction.

Wide Operating Wavelength and Temperature Range

Supports 1260–1620 nm broadband applications, operating temperature 0–70 ℃, storage temperature -40–85 ℃, suitable for indoor equipment rooms and most engineering environments.

High Reliability Design

Complies with ITU-T G.694.2 and RoHS standards, ensuring long-term operational reliability, suitable for carrier-grade system deployment.
