Product description: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.

INTRODUCTION:

DCM(dispersion compensation module)Product description

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>100Kmbecause of the dispersion influence, it will lead to the high error rate. CATV optical fiber system, transmission 

distance>100Km. It also lead to CSO deteriorationso that 550862MHz 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
