Product Description

HDCM-F DCM
CATV Optical fiber 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>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 Module ( DCM ). Adopt dispersion compensation module (DCM, DCF) is not only can compensate standard single mode optical fiber extra dispersion effectively, but also can 100% compensate standard single mode chromatic dispersion gradient.
AITC HDCM-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.

Poduct 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. Dispersion compensation value range is 10~120Km optional.
4. Low insertion loss, low polarized mode dispersion.

Main application
