Description
The product is high output power C-Band Er-Yb co-doped double
cladding optical fiber amplifier. The key components of the product are high
reliability multimode PUMP laser and the double cladding optical fiber. A
proprietary ATC (Automatic Temperature Control) and APC (Automatic Power
Control) circuit insures the high stability and reliability output power, the
unique optical circuit design ensures the excellent optical performance. The
high stability and high precision MPU system to ensure the control, adjustment
and display are intelligent and easy.
This amplifier employ double cladding Erbium Ytterbium co-doped
fiber, and employ the high power multimode pump, with a 10 times Conversion
efficiency higher than the single mode general technology, and therefore have a
lower relative cost and more compact size and lower power consumption, in
particular, for FTTH or FTTB or other large distribution system applications.
Employ
intelligent temperature control system: (1)Adopt special temperature control
circuit，heat radiating and power consumption can be reduced 30%, (2)The
professional air flow design can also ensure the best temperature stability, at
the same time powerful fan will start when the case temperature is over 45℃, meanwhile
it will stop as the temperature is under 40℃.The technology makes sure the
thermal stability of system and fan’s long life.
Intelligent network management system. Perfectly network interface:
Ethernet network，and the open network management interface ensure the connectivity
with all other network management system.
These products are widely used in CATV transmission system and the
high power distributing system FTTH requirement. It can be used for CATV
analog/digital signal distribution, or match with PON system to construction
the triple network integration. (Triple wavelength WDM is optional)
