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.
一个典型的在线光性能监测(OPM)模块能够在线监测通道光功率、中心波长及光信噪比(OSNR)等指标。 - 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).
系统传输480km后;MPI R点的光信噪比(OSNR)大于29dB;在误码率(BER)为10-12时;接收机的最小接收功率可达到-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.
将偏振扰频器与基本正交偏振分束探测相结合,首先由偏振信号光功率PS和消偏的背景噪声PN得到光信噪比(OSNR),然后再通过OSNR与偏振度(DOP)的关系来实现多信道DOP的监测。 - 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.
拉曼放大器会随著不一样的激发机制而有不一样的杂讯表现方式,因此研究激发机制就是一个好的研究方向。 - 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).
而动态增益均衡器（DGE）可以均衡由于这些原因引起的光通道功率变化和改善波道间信噪比的不一致。
