You can see the CWDM mux listed on their site, and they will also make custom mux for you.
Let me know if you need a Sales Contact for them.. My last set of muxes from them were custom muxes and they were able to get me a configuration with a lower insertion loss than what is listed on their website. ( I paid a small premium for that feature, which I was very happy to). Regards.
