Recommended configuration |
|
* This recommended configuration is only for giving general ideas. Please refer to the
operation manual which is included with the product when you use the product. The
operation manual shows you the appropriate way to use with any note. (1) For proper adjustment, make optical connection prior to electrical connection otherwise the product may get damage. The optical connection between the product and a power meter, or between the product and a laser source should be made when laser source is off. |
|
Any risk of making connection while laser source is working, such as loss of eyesight, should be at the user. |
|
(2) |
The input fiber of the modulator must be optically adjusted with an optical laser source. The schematic diagram is illustrated below. |
|
(3) |
The output fiber of the modulator must be optically adjusted with a power meter. The schematic diagram is illustrated below. |
|
(4) |
You can work the laser source. |
|
(5) |
Adjust the input side connector appropriately so that the input light power to the module
is maximized. The internal polarizer will get damage by improper adjustment and cause unexpected optical loss. |
|
(6) |
DC Supply is connected to Auto Bias Circuit. Auto Bias Circuit and Drivers are appropriately connected to modulator electrical inputs. The schematic diagram is illustrated below. |
|
*Addendum Input pulse signal from first RF port, and input data signal from second RF port. Both electrical signals should be synchronized each other. |
