Description

Product description: HA***0/F Negative Dispersion Fiber amplifier, not only amplifies the power of the input optic signal, but also generates a negative cost which can be used as dispersion compensation in standard single-mode fiber ***0nm extra-long trunk. Standard single mode fiber, dispersion exists on ***0nm medium. Typical value is *7ps/nm.km. Dispersion restricts the transmission distance and usable bandwidth of ***0nm fiber network, In the condition of super long truck with the distance ≥**0km, dispersion will cause HF CSO deterioration, it is impossible to realize Digital TV transmission for **0~**0MHz. At present, dispersion compensation component mainly contains Dispersion Compensation fiber (DSF) and Chirp Fiber Grating (CFG). CFG compensation module can only has its influence towards the accurate wavelength and suitable for single wavelength transmission. DCF is one kind of special type fiber commercialized, it has excellent negative dispersion features. Typical value is **0~***0ps/nmKm. It is one kind of mature component for dispersion compensation and has widely adopted high speed communication line. DCF has two mainly disadvantages: one is high attenuator value(normally is 0.5~2dB/Km):the other is short Mode Field Diameter and high un-linearity. That is the main reason that DCF are not able to applied in CATV series flexibly. Huatai HA***0/F, Negative Dispersion Fiber amplifier, integrates DCF into fiber amplifier casing, overcomes its disadvantage of high attenuator value and short Mode Field Diameter. Negative Dispersion Fiber amplifier can be designed and budgeted in system exactly same as the normal fiber amplifier. Product feature: High compensation rate: ***0ps/nm~****0ps/nm Operation flexibly: can be placed in any position of optical fiber link
