Tri-band optical filters are used for wave division multiplexing (WDM) in fiber to the home or business (FTTx) applications. Iridian’s WDM triband filters for FTTx applications have been described as the best in the world by some of our customers.
Iridian FTTx Filters Advantage:
Iridian’s tri-band FTTx filters feature very sharp transition between the reflect and pass bands while still maintaining very low insertion loss and pass band ripple. Our standard FTTx product line includes both shortpass filters (SPF) and longpass filters (LPF) for a range of wavelengths (UV, visible and NIR – 400 to 2200nm) and for various angles of incidence (AOI). Extra wide wavelength blocking is also available.
WDM LPF Tri-band Filter
Part Number: ZZ000306
Longpass, Shortpass and Tri-band optical filters are used for wave division multiplexing (WDM) in fiber to the home or business (FTTx) applications. The high performance and low cost characteristics make Iridian's FTTx products particularly attractive.

WDM SPF Tri-band Filter
Part Number: ZZ000307
Iridian's WDM Tri-band filters have been described as the best in the world by some of our customers. Iridian designs WDM Tri-band filters to have a very sharp transition between the reflect band and the pass band while still maintaining a very low insertion loss and pass band ripple. Short-pass and Long-pass filters are available for a wide range of wavelengths (UV, visible and NIR, i.e., 400 to 2200 nm) and for different angles of incidences. Note that extra wide wavelength blocking is an option for these types of filters.
