4 port WDM PON High power 1550nm EDFA optical amplifier CATV with WDM JDSU pump
Product Overview
JZEYDFA CATV analog optical fiber amplifier executive standard: GY/T184-2002 "Specifications and methods of measurements on analog fiber amplifiers used in CATV system”It adopt multiple mode high power pump laser from world famous semiconductor company like JDS,Lumics etc.Built in optical power output stable circuit and laser thermoelectric refrigerator temperature stability control circuit, which ensure the best performance of the machine and long service life of laser.Microprocessor software monitor the working state of the laser, the working parameters will be displayed by digital panel (LCD).Once the working parameters of laser deviation software Settings allow range, the microprocessor will automatically shut off the laser power, red light flashing reminder alarm, digital panel indicate the cause of the problem.
Features
- High Quality:Adopting international famous multiple mode high power pump laser.940nm and 980nm double pump laser.Low noise,low distortion,wide band,high power output.The power reasonably optimized by the software maximally reduces NF of EDFA,which is as good as common EDFA,also makes the system have excellent CNP
- Adopting Canada CorActice high performance erbium ytterbium fiber, high efficiency of energy conversion
- Output optical power (APC) function, with overload protection and laser overheating protection. Output gain (attenuation) adjustment function, adjustable range of -5~0dBm, adjust accuracy of 0.1dBm. Input and output both with optical isolation
- High reliability:With high performance switch power supply built-in,working voltage 85-265VAC,DC48V (option).ATC for head dissipation of case
- Intuition:The pump laser is the most valuable part of the machine. Built-in microprocessor used to monitoring the working state of the pump laser.Working parameters are displayed by the panel LCD window. The device has a power indicator, with function of screen display and alarm function. LED panel display configuration parameters and operating conditions
- Network type: optional type monitoring transponder meet the national standard and compatible with SCTE HMS standard,which realize the network monitoring function.
- Through the RJ45 interface (RS-485 or RS-232 option) to provide network management functions, using the standard SNMP V2 protocol. MIBs library provided by equipment manufacturers freely which support the third webmaster.Monitoring functions includes optical input power, optical output power, pump laser current, power supply voltage, etc.. The monitoring parameters include optical input power, optical output power, pump laser current, power supply voltage, etc.
- Power plug type: Aluminum plug switch power supply is conducive to heat dissipation and replacement. Dual redundancy power supply design,hot backup, supports automatic switching, hot plug
- High output power: synthesis of maximum output power of up to 4W ~ 10W
- Integratable WDM:It will be more concise used in GPON, EPON
