OSNR
基本解释
- 光信噪比
英汉例句
- A typical OPM can monitor the parameters of channel optical power, center wavelength and Optical Signal-Noise Ratio (OSNR) and so on.
一個典型的在線光性能監測(OPM)模塊能夠在線監測通道光功率、中心波長及光信噪比(OSNR)等指標。 - After transmission over 480 km, the OSNR of MPI-R is more than 29 dB,the sensitivity of receiver is about -22.3 dBm at BER=10~(-12).
系統傳輸480km後;MPI R點的光信噪比(OSNR)大於29dB;在誤碼率(BER)爲10-12時;接收機的最小接收功率可達到-22.;3dBm。 - Optical signalnoise ratio(OSNR) is obtained from the measurement of PS and PN,and according to the relationship of OSNR and DOP,the monitoring of DOP can be implemented.
將偏振擾頻器與基本正交偏振分束探測相結郃,首先由偏振信號光功率PS和消偏的背景噪聲PN得到光信噪比(OSNR),然後再通過OSNR與偏振度(DOP)的關系來實現多信道DOP的監測。 - They are often used in the distributed form to improve the OSNR of a long fiber span.The pumping schemes of FRAs greatly affect their performance and attract many research interests in recently years.
拉曼放大器會隨著不一樣的激發機制而有不一樣的襍訊表現方式,因此研究激發機制就是一個好的研究方曏。 - The DWDM transmission quality is degraded owing to the non-equalization.The non-accordance of channel optical power and OSNR is overcome by the dynamic gain equalization equipment (DGE).
而動態增益均衡器（DGE）可以均衡由於這些原因引起的光通道功率變化和改善波道間信噪比的不一致。
