OPA-1240 EDFA With GFF for DWDM System(BA,LA,PA)
   Content
Description
OPA-1240 is a kind of spectrum flat EDFA for DWDM system, The stability Pump laser and unique ATC (automatic temperature control) and APC (automatic power control) circuit are employed in it as the key component to ensure the high stability and reliability of output power. The unique optical circuit design ensures the excellent optical character. The high stability and high precision MPU system are employed to ensure the control adjustment and display is intelligent and easy.
 
Professional design GFF (gain flattening filter) with excellent optical path design make flatness and noise reach the best optimization. It can provide 40~80 channels, and above 35nm flatness.
 
The optical circuit is designed especially for digital optical fiber communication system including
(1) lower noise figure
(2) high output booster and high sensitivity Pre-Amplifier improve the system loss budget
(3) Broad input power range and output power adjustable make it use easily.
The design of dual Power Mixed and hot swap make it has longer MTBF. Also, the power system can be backup.
 
Employ the intelligent temperature control system, the fan is on when the module temperature over 45℃, meanwhile it will stop as the temperature is under 40℃, which makes sure the thermal stability and fan’s long life-time, meanwhile, the professional air flow design can also ensure the best temperature stability.
Intelligent network management system, perfectly network interface: Ethernet, RS-485 and RS-232 network interface, and the open MIB ensures the connectivity with all other network management system.
 
Features
(1) Low Noise Figure: Typical 4.5dB.
(2) High Flatness: Typical 1dB.
(3) Cover Whole C-Band: Carrie 40 or 80 CHs.
(4) Redundancy hot swap power module: 110/220VAC and 48VDC can plug Mix.
(5) Perfect Network Interface: Ethernet, RS-485 and RS-232 port.
(6) Support Telnet and SNMP network management.
(7) Gain can be adjustable by network and manual.
(8) High Precise AGC and ATC Circuit.
(9) High saturation output power.
(10) Flexible Mechanics and Circuit structure (Module, 1U rack and Gain Block).
(11) OEM is available.
 
Application
(1) Pre-Amplifier
(2) Online Amplifier
(3) Booster
(4) DWDM Optical System
