Polarization Maintaining WDM 980/1550nm

SKU: PMDM

The PMDM 980/1550 is a 1×2 Wavelength Division Multiplexer (WDM) that combines a 980 nm pump laser with a 1550 nm signal laser into a single polarization-maintaining fiber. The pump input supports either PM980 or HI1060 (non-PM) fiber. Utilizing thin-film coating technology and a proprietary micro-optics packaging design, the PMDM enables efficient optical addition at 980 nm while maintaining low insertion loss, high channel isolation, wide passband, low temperature sensitivity, and an epoxy-free optical path. The device meets Telcordia GR-1221-CORE reliability standards, including impact, vibration, thermal shock, and temperature cycling tests.
