PRODUCT DESCRIPTION
ITU G.652 standard single-mode fiber has dispersion in C-Band, the typical value is 16.6ps/nm Km dispersion. Dispersion limits the transmission distance of 1550nm optical fiber system and the available bandwidth.
There are several methods of optical fiber dispersion compensation. Practice proved that the dispersion compensation fiber module (DCF, DCM) is the method is simple, the most economical, effective. It can not only effectively extra dispersion compensation of standard single mode fiber, dispersion slope compensation can also be 100% standard single mode fiber.
DCM-60K dispersion compensation fiber module, is negative dispersion compensation based on optical fiber technology, can effectively compensate for G.652 standard single-mode fiber transmission band of 1525 ~ 1565nm dispersion and dispersion slope characteristic.
