Applications
• Distributed temperature System
Characteristics
• Low attenuation at DTS operating wavelength 1450nm, 1550nm and 1650nm
• High bandwidth at C-band (especially at 1550nm)
• High temperature resistance
• Low splicing loss
• Excellent bending insensitivity
Compared with communication multimode fiber, the advantages of DTS-MMF are as follows:
1.Low attenuation at DTS operating wavelength
The lower attenuation of the DTS-MMF at the wavelength of 1450nm, 1550nm and 1650nm can increase
the distance of the distributed temperature measurement system.
2.High bandwidth at 1550nm
According to IEC 60793-1-41-2010 (bandwidth), the actual measured bandwidth at 1550nm of DTS-MMF
can exceed more than 1000MHz·km, which effectively improves the spatial resolution of the long-distance
distributed temperature measurement system.
