OSNR
基本解釋
- 光信噪比
英漢例句
- A typical OPM can monitor the parameters of channel optical power, center wavelength and Optical Signal-Noise Ratio (OSNR) and so on.
一個(gè)典型的在線光性能監(jiān)測(OPM)模塊能夠在線監(jiān)測通道光功率、中心波長及光信噪比(OSNR)等指標(biāo)。 - 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(tǒng)傳輸480km後;MPI R點(diǎn)的光信噪比(OSNR)大於29dB;在誤碼率(BER)爲(wèi)10-12時(shí);接收機(jī)的最小接收功率可達(dá)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(jié)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(guān)系來實(shí)現(xiàn)多信道DOP的監(jiān)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(fā)機(jī)制而有不一樣的襍訊表現(xiàn)方式,因此研究激發(fā)機(jī)制就是一個(gè)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(dòng)態(tài)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。
