We have provide WDM for Raman DTS from 2003 year, developing the key optic passive components for Raman temperature distributer and monitor system.
Over 10 year's promotion, we providing special optic WDM for Raman DTS, continuously improving according to our customers' usage condition,now,these parts and assembly can work at different areas, including ultra-cold area, ultra-high temperature area, and so on.
We get the update of WDM for Raman DTS at May,2014,especially for:
1. More less insertion loss for SR and ASR channel in reall Raman system.
2. Keep balance between SR and ASR signal.
3. Isolation from 40dB to 60dB ,for SR and ASR channel,for high resolution of Raman system.
At the same time, we've developed the 1064nn/1116nm/1016nm WDM for Raman high temperature application.
