650 系列光纤故障定位仪
我们使用 MWQ LD 作为 650 系列光纤故障定位仪的发光组件。由恒流源驱动，可以布防指示灯稳定的红色激光。产品可以用来检查光纤故障，当他们与光学接口连接，并将插入单模或多模光纤。它是在纤维项目建设、 纤维网工作维护、 光学组件制造和研究不可或缺的工具。
技术参数:
光源波长: 650 + 10nm
适用光纤类型: 单模式或多模式
输出功率在单模式: 10 mW
动力: 两个 1.5 v 电池
权力的连续工作时间: ≥20 小时
工作温度: 10 ~ + 60 ℃ (不结露)
存储温度:-40 ~ + 85 ℃
外壳材质: 铜合金或不锈钢
尺寸: φ24 * 170 毫米 (没有接口)
外部结构:

1 防尘盖 2 光学接口 3 头的指标
4 LED 5 开关 6 身体 7 尾
使用方法:
1.拧开到尾巴，尾巴，再放入两个 1.5 v 电池。(警告: 电池点至底部的定位器，定位器的电池接触阴极阴极阳极)。
2.连接身体夹着尾巴，并打开防尘盖，然后按下开关。你会看到红色激光发光从光学接口，同时，LED 将照亮 (请别盯着看梁，为了不损害你的眼睛)。
3.按下开关再次，发光的变化对脉冲模式下，并与发光 LED 同步 (脉冲频率将控制在 0.5-2.0 Hz)。
4.再次按下开关，光源将关闭，而且还有没有更多的光线。同时，LED 熄灭 (开关的周期模式是: 连续脉冲关闭)。
5.你应该插入的纤维，你想要检查到光学界面，然后按下开关选择光源的工作模式 (连续或脉冲)。
6.当你完成的检查，请拧上防尘盖。如果你不使用指标很长时间，你必须拿出电池，以防电池腐烂和摧毁光源。
维护和注意事项:
1.激光是有害的所以特别是，你必须保护你的眼睛。当 LD 工作，请不要让你的眼睛暴露在激光。
2.一般来说，温度越高，越短的激光器避免温度过高的生活当你使用它时。
3.纤维头必须清理，而劳工处经营。
4.如果不使用此灯源，请拧上防尘盖，以免灰尘落入。
5.如当你不使用它，将电池取出。

650 series fiber fault locator
We use MWQ-LD as the emitting component of 650 series fiber fault locator. Driven by constant current source, the indicator can emit stable red laser. The product can be used to inspect fiber failure when they connect with optical interface and be inserted into single mode or multi mode optical fiber. It is indispensable tool in fiber project constructing, fiber net-work maintaining, optical component manufacture and research.
Technical parameter:
Wavelength of optical source: 650+10nm
Applicable fiber type: single mode or multi mode
Output power in single mode: 10 mW
Power: two 1.5V batteries
Continuous working time of power: ≥20 hours
Working temperature: 10~+60℃ (not dewing)
Storage temperature: -40~+85℃
Material of the shell: Cu-alloy or stainless steel
Dimension: φ24*170mm (without interface)
Outer structure:

1-dust cap 2-optical interface 3-head of the indicator
4-LED 5-switch 6-body 7-tail
Usage:
1. Screw off the tail, then put two 1.5V batteries into the tail, . (Caution: anode of batteries point to bottom of the locator, cathode of batteries contact cathode of the locator) .
2. Connect the body with the tail, and open dust cap, then press the switch. You will see the red laser emitting from the optical interface, at the same time, LED will be lighted up (Please don't stare at the beam, for fear of damaging your eyes) .
3. Press the switch again, light-emitting changes to pulse mode, and LED synchronize with light-emitting (pulse frequency will be controlled at 0.5-2.0 Hz ) .
4. Press the switch again, the optical source will shut, and there is no more light. Meanwhile, LED put out (Switching cycle mode is: continuous-pulse-shut) .
5. You should insert the fiber which you want to inspect into optical interface, then press the switch to choose working mode of the light source (continuous or pulse) .
6. When you finish the inspection, please screw on the dust cap. If you don't use the indicator for a long time, you must take out the batteries, in case that batteries rot and destroy light source.
Maintenance and attentions:
1. Laser is harmful, so especially, you must protect your eyes. When the LD working, please don't let your eyes exposure to laser.
2. Generally, the higher is temperature, the shorter is life of the LD. Avoiding high temperature when you use it.
3. The head of fiber must cleared up while the LD operates.
4. If don't use this light source, please screw on the dust cap in case that the dust fall into.
5. Take out the batteries when you don't use it.
