Product Description
Raman Fiber Optic Sensor are wildely used in distributing temperature sensor.
We provide multimode and singlemode fiber optic WDM for DTS system.
1550nm-input while 1450nm, 1650nm output with low loss, .
We provide special optic WDM for Raman DTS from 2003 year, developing the key optic components for Raman temperature distributor and monitor system.
Over 10 year's promotion, our Raman WDM not only made by different type optic fiber(SMF, 50/125, 62.5/125) but also different wavelength(1550nm, 1064nm, etc. )
At May 20, 2014, we update the craft of WDM for Raman DTS, special at:
More less insertion loss in real Raman system; More balance between SR and ASR; Less mis-match of multimode laser etc.
In the same time, we have developing Raman WDM for 1064nm/1016/1116nm wavelength, for more high temperature application.

Shanghai Changing Communication Technology Inc. Changing established in Shanghai---the financial center of China, is a leading international manufacturer of fiber optic passive components, including connectors, couplers, adapters, WDM and fiber optic splitter.
Over 10 years 0f reliability R&D experience base on Chinese national institute for passive optic components, we produce huge quantities on a high level of quality matching highest demands. Most of productions are used in national telecom. System, military system, fiber optic sensor industry, optic laser industry, oil field etc.
Three major producing lines set up in 2009, including, fusing bi-conical taper(FBT) producing line, optic fiber Polish producing line, micro-optic assembly producing line, accordingly, we are original manufacturer of optic fiber inter-connector, coupler, WDM and splitter.
Base on very deep research in fused bi-conical taper fiber technology, we find many factors infect performance and reliability of FBT coupler, providing high reliability production including: Dual/Tri-windows optic splitter, singlemode monlinthical single fused 1*3, 3*3, 1*4 dual-windows splitter, multimode mode insensitive splitter, high power large core multimode 1*16 or 16*1 fiber splitter / combiner, 1310/1490/1550nm WDM, online optic attenuators.
Optic Polish line providing very excellent end to end interconnection connectors, but we still focus on special requirement connectors product, like hash environment connectors, waterproof optic connectors and adaptor, military field connectors, ODC outdoor connectors serial production, we also provide OEM and ODM to new required construction connectors.
Precise assembly workstation can make micro-optic components. Base on this workstation, we mass producing PLC optic splitter, CWDM, DWDM etc.
For minimizing the cost, we reduce all cost we can, provide best price/quality for customers while minimum order.
ODM and OEM with quality delivery.
