Main Optical Parameters:

Table 1; main optical parameters

1. Status display panel operation method:

The machine's microprocessor software work with the laser status monitoring, digital board display, fault alarm, network management and other functions. Pressing the front panel of the machine ●, ● button to turn the key to show the machine operating parameters.Model 1550-15、1550-16、1550-17、1550-18、1550-19、1550-20、1550-21、1550-22、

1550-23、1550-24、1550-25、1550-26、1550-27

2. +5 V voltage (+5 VREADS)> ± 0.5V will prompt alarm.

3.-5V voltage (-5VREADS)> ± 0.5V will prompt alarm.

4. laser temperature (TEMP): ℃, the machine laser set at 20 ℃ -30 ℃ to work norm is, when the test temperature exceeds this range, LCD display "READY", red warning flashing prompts, and automatically off off laser power.

5. cooling / heating (COOLING / HEATING): laser show in order to maintain the temperature in the standard the occasion of the 25 ℃, the thermo electric cooler in the heating or cooling when the operating current. (MA)

In the hot environment, LCD display COOLING (cooling).

In the cold environment, LCD display HEATING (heating).

6. the bias current (BIAS): laser bias current is the main operating parameters of lasers, when the parameter exceeds setting value, you will be prompted alarm and automatically shutdown laser power, laser protection.

7. the output optical power (OUTPUT): shows like the back of the machine output power. (DBm)

Permissible error, <± 0.2 dBm,

No light input, pump laser power supply shutdown, will show no light output (NO OUTPUT).

8. input optical power (INPUT): shows the back panel of the input optical power (dBm).

Input power> +10 dBm, you will be prompted alarm;

Matt input alarm, input power <-12 dBm, will show NO INPUT LOM, automatically breaking work of pump laser bias;

Input optical power> 0 dBm, to achieve the rated output power.

The proposed low-power-type input optical power-12dbm to +2 dbm

9. the machine factory serial number: S / N:

10. address code: R232 plug set by the user for the network

2.  State of alarm note

The machine front panel power switch next to a working state indicator (Optical). Green display is working properly, the red laser is not displayed to enter the work, the red light flashing display alarm.

1. then plug in the power line plug 220V power supply, such as the machine normally, digital panel displays "CONTROL OFF", the red light.

2. Press the previous version of the radio button, automatically connected to laser power, the status light from the red light into green light, the digital panel display  OUTPUT *** / INPUT *** This machine is working properly.

3. pressing the STATUS button to display the parameters for this.

4. input optical power <-12dBm, will show NO INPUT, can not boot, red light.

5. the machine status display in the 2-8 items within any exception occurs, the alarm will be prompted (red flashing), the microprocessor will automatically turn off laser power, the digital board show the cause.

6. for the protection of laser safety, laser power of this machine with delay function, that is, when the key turned on, the need to delay for 10 seconds, the laser to enter  the work.

3. Handling Precautions

12．1 Environmental conditions

1.Do not expose the module to any flammable or dissolved in the nature of the environment

l2. to keep clean the module, please use in a clean environment.

l3. Do not attempt to repair or demolish blocks

l4. mobile module or fiber optic connection when not in use to set caps on the protection of

l5. Do not bend, pulling pigtails

6.transport, package, pigtails bending radius should be larger than 40 mm

12．2 ESD protection to attention

This product is electrostatic-sensitive ESD devices, which use a lot of the static-sensitive optoelectronic devices, can only be used in anti-static work area. Please observe the following rules to eliminate the static effect:

1.region in anti-static installation, use

l2. module should be placed on the table in anti-static work

l3. Users must be well grounded body

l4. in direct skin contact with the module must wear anti-static wrist

l5. easy to produce static electricity in the dry so be careful with the environment protection within the static

l6. operator's feet must touch the ground

l7. using semiconductor materials such as desktop

Operation at any time, static-sensitive devices such as optoelectronic devices can not be taken lightly. Also, exposed beams is dangerous, certainly, to prevent damage to the laser beam.

12．3 Optical connector Maintenance Notice

Optical connector cleaning is an important optical amplifier, a maintenance. To achieve safe and effective for cleaning, please observe the following rules:

1.Use of anhydrous alcohol and absorbent cotton or other special wipes clean fiber end face

2.dip ethanol touch light connector end face, sticking out-side surface of the dust and other debris

3.Do not force back and forth in the optical connector end face cleaning, so as not to scratch the face

4.still can not connect the first light output when cleaning work to prevent face injury
