Appendix
Optical loss measurements
The first step in setting reference (Reference) value
Open the NKOPM-21A optical power meter, by a key to select the correct working wavelength.
Open source (emission source), select the correct wavelength and make it stable (this process takes approximately 1-2 minutes).
The choice of a root is used for connecting the light source of optical fiber jumper, which we call the emission source jumper, clean emission jumper connector. Note: the emission source used by the optical fiber jumper must use by optical fiber. The optical fiber link is the same.
With the emission source jumper will light source (emission source) is connected with the NKOPM-21A optical power meter.
Optical power at this time of the value obtained by NKOPM-21A.
Note: the power of the value should be with the light source (emission source) itself set close to the value, if there is a big deviation, please pay attention to carefully clean the respective connecting end face or the timely replacement of emission source jumper.
The dB key press NKOPM-21A optical power meter, when the NKOPM-21A dB reading of 0, and at the same time the light power of the measured values are set to be the benchmark (Reference) value.
Note: NKOPM-21A is zero, the number of digits after the decimal point with minor changes, this is a normal phenomenon.
The second step optical link loss measurement
Keep the emission source jumper and light source (emission source) connection.
The light source (emission source) and NKOPM-21A respectively and the optical fiber links need to connect.
Note: clean connection end all, including fiber optic adapter required.
At this time NKOPM-21A readings is the loss to test the fiber link, the unit is dB (absolute optical power current value and display by dBm

光纤损耗测量

第一步设定基准（参考）值

打开NKOPM-21A光功率计，通过λ键来选择正确的工作波长。

打开光源（发射源），选择正确的波长并使其稳定（本过程大约需要1-2分钟）。

选择一根用来连接光源的光纤跳线，我们称之为发射源跳线，清洁发射跳线的连接器。注意：发射源跳线所使用的光纤必须与被测光纤链路所使用的光纤相同。

用发射源跳线将光源（发射源）与NKOPM-21A光功率计相连。

用NKOPM-21A得到此时的光功率值。

注意：此时测得的功率值应该与光源（发射源）本身的设定值相近，如果有较大偏差，请注意仔细清洁各个连接端面或者及时更换发射源跳线。

按NKOPM-21A光功率计的dB键，此时NKOPM-21A的dB的读数为0.00，并同时将所测的光功率值设置成为基准（参考）值。

注意：NKOPM-21A归零后，小数点后的位数会有轻微变化，这是正常现象。

第二步光纤链路损耗测量

保持发射源跳线与光源（发射源）的连接。

把光源（发射源）与NKOPM-21A分别和需要的光纤链路进行连接。

注意：清洁所有的连接端面，包括所需的光纤适配器。

此时NKOPM-21A显示的读数就是被测光纤链路的损耗，单位为dB（同时以dBm方式显示当前的绝对光功率值）。

Can simultaneously measure and display the power of uplink and downlink wavelength 1310 1490 and 1550 three wavelength values.
The standard configuration:
The host (including rechargeable lithium battery), a rubber protection sleeve, USB data transmission line, the driver software CD, AC adapter, product warranty card, clean cotton swab.
The above parameters and configuration of any change without notice

◆ 产品概述

NKPON-21光功率测试仪是我公司专门针对FTTx/PON 无源光网络测试推出的新款测试仪表,采用了高清的TFT彩色液晶，可在BPON/EPON/GPON架构上实验语音、数据和视频信号的同步测量和显示。还可设置功率阈值，对每个波长提供通过、警告或未通过状态指示。是PON网络工程、施工和维护的理想选择。

◆ 产品特点
1.滤波测量功能，同时测试PON系统中的1490nm，1550nm，1310nm三种波长相应的功率值。
2.用于1310nm上行波长的突发模式测试。
3.双端口直通设计，测试期间可保证 OLT 到 ONT 的全程通讯。
4.通过、警告或未通过指示，3个指示灯直观显示被测光路状态。
5.易于使用，只需连接光纤即可读取结果。
6. 高清的TFT彩色液晶

7.通过USB进行数据传送，方便快捷。
8.200条记录可在设备或上机位软件中保存，查看，删除。
9.通过后台软件设置阈值，上传数据，校准波长。
10.自动关机功能，并可在设备上进行时间设置、阈值设置。
