INTRODUCTION:
DCM(dispersion compensation module) - Product descript ion
ITU G.652 standard single mode fiber (SMF-28). It has dispersion at 1550nm (C-Band).Dispersion
typical data is 17ps/nm·Km. It limits 1550nm optical fiber system transmission distance and
bandwidth. 2.5Gb/s optical fiber system, transmission distance>100Km，because of the dispersion influence, it will lead to the high error rate. CATV optical fiber system, transmission
distance>100Km. It also lead to CSO deterioration，so that 550～862MHz can not realize digital
CATV transmission.
There are many ways of Optical fiber dispersion compensation. It has already proved that it
is the simple, economic, effective method if you adopt dispersion compensation module (DCM, DCF).
It is not only can compensate standard single mode optical fiber extra dispersion effectively,
but also can 100% compensate standard single mode chromatic dispersion gradient.DCM-FC
dispersion compensation optical fiber module is based on negative dispersion compensation
optical fiber technology. It can compensate standard single mode optical fiber of 1525~1565nm
effectively 1525~1565nm to fit for its dispersion feature and slope characteristic.
DCM(dispersion compensation module) - Product feature
1 Adapt to standard single mode optical fiber SMF-28 (ITU G.652), 1525~1565nm transmission channel
2 Excellent dispersion compensation feature can eliminate the influence to
system’s index, because of residual dispersion.
3 1525~1565nm transmission channel. 100% dispersion slope compensation.
4 Dispersion compensation value range is 10~120Km optional.
5 Low insert loss, low polarized mode dispersion.
6 Excellent performance price ratio.
DCM(dispersion compensation module) - Main applicatio
1) ITU G.652 standard single mode optical fiber (SMF-28), 1525~1565nm wavelength
range dispersion and slope compensation.
2) Long distance, over length optical fiber link .
3) DWDM system
4) 10Gb/s, 40Gb/s high-speed optical fiber communication system.
5) CATV over length trunk line.
6) Satellite, microwave long distance optical fiber link .
