Description:
The EDFA is high output power C-Band
Er-Yb co-doped double cladding optical fiber amplifier built-in catv transmitter. 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.
Intelligent network management system.
Perfectly network interface: Ethernet, RS-485 and RS-232 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)
