PM 2000nm-DWDM 3Port Device

This Polarization-Maintaining (PM) 2000 nm 3-Port DWDM module provides low insertion loss and high channel isolation for precise wavelength separation in polarization-sensitive optical systems. Designed to transmit the 2000 nm channel while reflecting the 1550 nm signal, it maintains high stability with minimal temperature-dependent loss and wavelength shift, ensuring reliable performance across its operating range.

Ideal for channel add/drop, DWDM networks, wavelength routing, and fiber amplifier systems, the module supports both fast and slow axis operation using PM Panda fiber in a compact, epoxy-free design. Custom configurations including fiber type, connector style, and cable length are available to meet specific system integration requirements.
