DCM-FC Dispersion Compensation Module
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>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.
Idealphotonics 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
Feathure
Adapt to standard single mode optical fiber SMF-28 (ITU G.652), 1525~1565nm
transmission channel
Excellent dispersion compensation
feature can eliminate the influence to system's index, because of residual
dispersion.
1525~1565nm transmission channel. 100% dispersion slope compensation.
Dispersion compensation value range is 10~120Kmoptional.
Low insertion loss, low polarized mode dispersion.
Excellent performance price ratio.
Application
ITU G.652 standard single mode optical fiber
(SMF-28), 1525~1565nm wavelength range dispersion and slope compensation.
DWDM system
10Gb/s, 40Gb/s high speed optical fiber communication system.
CATV over length trunk line.
Satellite, micro-wave long distance optical fiber link
