Polarization Maintaining DWDM Multiplexer 48 Channel 100GHz For C-Band DWDM / ROADM

The PM-AAWG-48CH-100G-F&G-Module is a polarization-maintaining (PM), thermally stabilized Arrayed Waveguide Grating (AAWG) multiplexer/demultiplexer module designed for C-band DWDM systems. Operating within a wavelength range of approximately 1525 to 1565 nm, the module supports a total of 48 channels corresponding to the ITU-T Grid C15–C62, featuring a channel spacing of 100 GHz (equivalent to a wavelength spacing of approximately 0.8 nm). The product utilizes a "Flat-top" passband design, ensuring excellent power flatness and filtering characteristics across its effective bandwidth. As indicated in the specifications, the module employs PM1550 polarization-maintaining fiber for its pigtails; by default, the connectors are aligned to the slow axis key, thereby facilitating superior preservation of polarization states. This makes the module particularly well-suited for coherent communication systems, as well as for high-order DWDM applications that demand exceptional polarization stability and channel consistency. The unit is housed in a compact 120 * 70 * 11 mm metal package, allowing for easy integration into 1U or 2U chassis and sub-modules.
