4 Channel 200G O-Band Polarization Maintaining Dense Wavelength Division Multiplexing Module

This 4-channel, 200 GHz O-Band PM DWDM module is a polarization-maintaining (PM) Dense Wavelength Division Multiplexing/Demultiplexing unit operating within the O-band. Specifically designed for the 1260–1380 nm wavelength window, it utilizes a 200 GHz channel spacing with center wavelengths centered at 1306.85 nm, 1309.14 nm, 1311.43 nm, and 1312.58 nm. It is ideally suited for carrying multiple high-speed data channels within the 1.3 µm low-dispersion window. The product features PM13-U25D polarization-maintaining fiber as its pigtail, supplied with a standard length of 1 meter, a 0.9 mm blue Hytrel jacket, and an FC/APC connector. With overall package dimensions of approximately 100 * 80 * 10 mm, the module is easily integrated into 1U/2U chassis or optical transceiver modules. Technical specifications indicate that the module is engineered to deliver a combination of low insertion loss, high extinction ratio, high channel isolation, and high reliability, while fully complying with Telcordia and RoHS standards.
