据日经电子学第376号报导,美国康宁玻璃公司已开始出售零色散波长为1.55μm的单模光纤。这个波长的传输损耗有0.22dB/km和0.27dB/km两种。波长在1.525～1.575μm之间,色散值优于±2.5ps·km~(-1)nm~(-1),模班为9μm。光纤长度除有6.4、5.3、4.4km
According to Nikkei Electronics No. 376, Corning Glass Corporation of America has begun selling single-mode fibers with zero-dispersion wavelength of 1.55μm. The transmission loss of this wavelength has 0.22dB / km and 0.27dB / km two kinds. The wavelength is between 1.525 and 1.575μm, the dispersion value is better than ± 2.5ps · km ~ (-1) nm ~ (-1) and the mode class is 9μm. In addition to fiber length 6.4,5.3,4.4km
