Tap Isolator/Filter Wavelength Division Multiplexer Hybrid (TIWDM Series)

Produts Details

Product Name: Tap Isolator/Filter Wavelength Division Multiplexer Hybrid (TIWDM Series)


The TIWDM series combines Filter WDM, Tap Coupler and Isolator into a compact package. This device is ideal for fiber amplifier application to provide input signal power monitoring, pump/signal multiplexing and isolation functions at the same time. It offers the advantages of cost saving, space saving, as well as performance improvement.
