铒离子受激发射波长(1.53～1.55μm)处于通讯用石英光纤最低损失波长带(1.55μm)内,掺高纯氧化铒的光导纤维(Erbium Doped Fiber:EDF)用作光放大器,把长距离通讯中的光衰减直接放大,有40分贝(放大因数=1万倍)的增益,可以实现无中继通讯,显示出它在现代通讯中的重要作用,继美国之后,当前世界发达国家都在实施信息高速公路计划,高纯氧化铒的用量方兴未艾。 Erbium-doped Erbium Doped Fiber (EDF) is used as an optical amplifier, and the long-distance (1.55-1.55μm) Erbium-doped optical fiber The optical attenuation in communications is directly amplified, with a gain of 40 dB (amplification factor = 10,000 times), enabling relayless communications, demonstrating its important role in modern communications. Following the United States, the current world’s developed countries are Implementation of information highway plan, the amount of high purity erbium oxide in the ascendant.
