1. PRODUCT DESCRIPTION
Erbium-doped fiber amplifier (EDFA) has advantages of low noise, high gain, wide
bandwidth, efficient pump and stable working condition etc. It is used in CATV system
widely.
As the transmitting nodes in the CATV system increase constantly, fiber to the home
(FTTH) and fiber to the building (FTTB) are popular. When the EDFA is used to cascaded
amplification in the CATV system, the C/N deterioration is serious, so the EDFA must
have high saturated output power, low distortion, while the saturated output power of
EDFA is usually between 13dBm and 23dBm, output power limit is about 27dBm. In
addition, the gain fiber of EDFA is single-mode and single-clad fiber, pump is directly
coupled into fiber core, while fiber core is very small, it is required the pump is
single-mode.
The output power of single-mode semi-conductor laser is just several hundred’s mW,
and it is limited by pump area, high power pump can’t be coupled, so it has a serious
effect on the output of fiber laser. In the face of this kind of situation, an international
new double-clad fiber has been developed. It takes advantage of envelope pump
technology, which overcomes shortcomings of the single-mode fiber, and makes output
power increased one to two orders of magnitude, and promotes the development of
high-power fiber amplifier. The factory overcomes multiple technical difficulties, and
then developing erbium ytterbium co-doped double-clad fiber amplifier which is fit to
CATV system to adapt current require of FTTH and FTTB.
This series of products produced by JDSU and Lumics etc---the famous brand
semiconductor firms as the pumping source. In the interior of the machine is equipped
with the light power export stable circuit and laser thermoelectric cooling device
temperature stability control circuit to ensure optimal machine performance and
long-life laser stability. The microprocessor software monitors the lasers’ working state,
the Digital Panel (VFD) displays the operating parameters. Once the laser operating
parameters deviate from the permissible range set by the software, micro-processing
will automatically turn off laser power, red light goes on to warn, digital panel prompts
cause of troubles., a detailed report of the device parameters please read "instructions."

6.7 Fan Status: Figure (1) page"6" and
page "4". The fan, a total of three kinds of
working state can be adopted .In the current
page, click the" "key to change the working
state, while in the "AUTO" state, when the
device internal temperature is higher than
45 ℃, the SCM will automatically open the
chassis fan to cool, and it will not close until the
temperature dropped to 35 ℃.
6.8 Parameters of Pump Laser:

of pump laser. As shown in Figure (2)
6.8.1 Pump Switch State: If there is no light power input, pump will keep close.
Figure (2)7.1.
6.8.2 Lead Pump Bias: Figure (2) 7.2, displaying LD bias currents in laser.
When the operating current is greater than 130% of rated current, the working life of
laser are affected, even damage the lasers. Therefore, when detected laser operating
current is greater than 130% of rated current. The internal hardware circuit of
equipment has limited its scope.
6.8.3 Lead Pump Temperature:
lasers work properly at 20 ℃~35 ℃
temperature range. 6.4 in Figure (2) 7.3.
LCD displays the actual temperature of
laser, such as "25.5℃", when the detected
temperature is 20~30℃, the LCD displays
real-time temperature.
6.8.4 Laser Cooling Current:
in Figure (2) 7.4. In order to ensure the
internal temperature of laser range from
20 ℃to 30 ℃, we should provide Thermoelectric cooling device a certain amount of
operating current. When the detected working current of thermoelectric cooling device
is within-1500mA~ +1500 mA, the LCD displays real-time current. When the current is
positive, the TEC cool.
