Product Details
Singlemode wavelength division multiplexer WDM
1310/1550,980/1550nm,1480/1550nm 1X2 2X2 combine or separate light
at different wavelengths. They offer very low insertion loss, low
polarization dependence, high isolation and excellent environmental
stability. These components have been extensively used in CATV, WDM
networks, Fiber sensor and fiber optics instrumentation.
Features:
