CATV PON WDM Fiber Amplifier 1550nm fiber amplifier RF signal input type 4output EDFA with JDSU pump laser
Product Overview
JZEDFA series 1550nm fiber amplifier is a important optical relay transmission equipment during 1550nm optical communication system.In order to reach high index and dependability, main instruments are all adopted imported famous brand to cooperate microprocessor automatic control circuit and high dependability switch power to assemble up. High dependability, low noise, especially double pump design makes noise index better. Each main technique performance index and technique plane can compare with foreign similar machine. And with high performance to price ratio, it is suitable for using at large or middle-size network.
Performance Characteristic
■ Adopt international famous brand pump laser with the advantage of low noise , low distortion, wide frequency band and, high output optical power.
■ Imported high-performance erbium-doped fiber, high energy conversion efficiency.
■ Support 1, 2, 3 or 4 output.
■ Support two detachable backup power supplies.when the power supply module failure, just pull out the fault power module.220 vac and 48 VDC power supply module for option.
■ Adopt radiator and fan cooling together, the cooling capacity tenfold increase.When the machine temperature more than 38 ℃, axial flow fan automatically start, regulate internal temperature, make the pump laser ATC control more accurate.
■ Built-in microprocessor automatic monitoring circuit, real-time accurate monitoring of all kinds of working state of the input and output power and laser light, make sure the stability of the optical output power, and prolong the working life of the laser
■.When the scope of work parameter deviates from the set of safety equipment, the device automatically shut off the laser power, sound and light alarm at the same time.
The output power is able to adjust 5dB lower by front panel button.
■ Built-in LCD display on the front panel, accurate display the working state parameters of the equipment accurately.
■ With RS232 interface,RS485 industrial standard interface and RJ45 Ethernet interface (option) .It meet the needs of the various conditions, making it easy for users to choose convenient network management environment.
■ Ethernet interface provides advanced network management function based on the SNMP protocol.Which meet the international standards.
■ Meantime with integrated network card , with functions of Web Server, through the Ethernet interface connected to the Internet network, complete equipment under the HTTP browsing capabilities.
