Primanex's wavelength division multiplexing (WDM) products are based on mature thin film interference filter technology, and are packaged by all-glass epoxy technique which ensures no epoxy within the light beam path. The products have low insertion loss, high isolation, return loss, stability and competitive cost structure. Primanex has over 10 years of volume manufacturing experience on WDM products, and is one of very few earliest vendors within China to have WDM capability. 
Primanex also develops high-end wavelength management products such as interleavers and tunable optical filters. The interleavers are based on Mach-Zehnder type polarization interferometer, and are designed to have “zero”-dispersion hence are perfect for high-speed 40G/100G systems which have very tight tolerances for the dispersion. The tunable optical filters are based on angle-tuning of thin-film optical interference filters, can be tuned across the whole C-band. 
Primanex WDMs have very wide products portfolio including CWDM, DWDM, and EWDM components and modules etc, which are widely used in cable TV network system, metro, long-haul and access network systems.
