详情

Description: The product is high stability output erbium-doped fiber amplifier EDFA (Erbium-doped Optical Fiber Amplifier). The core device is highly reliable Pump lasers, using a unique APC (automatic power control) and ATC (Automatic Temperature Control) circuit, enabling high output power stability, reliability and good; a unique optical design ensures excellent optical path indicators; use high stability and high precision of the MPU (microprocessor) systems use regulation, display convenient, reliable and intelligent. Using unique intelligent temperature control system, when the machine temperature is higher than *5 ℃, the powerful fan to work, the temperature below *0 ℃, the fan stops. Assurance system thermal stability and long-life fan. At the same time, professional cooling duct design to ensure optimum temperature stability. Intelligent monitoring and management system. Unique with RS**2, RS**5 and Ethernet, three kinds of network management interface, and open network management interface to ensure that any network management system connectivity. Features: ■ Low noise figure: 0dBm less than 4.5dB ■ Low CSO degradation: <**0dBc ■ Controllability and operability: Dual CPU dealt with separately low-level control loop and the upper interface ■ High stability and high reliability: HTTB> *****0 hours ■ High brightness VFD display status (1U structures) ■ Improve the network management interfaces: Ethernet, RS***5 and RS***2 network interface ■ High-precision AGC / APC and ATC circuits: power control accuracy of typically ± 0.*5dB, temperature control accuracy of <± 0.1 ℃ ■ Intelligent Temperature Control System: A special temperature control chip, heat and power consumption reduced by *0% compared with conventional products ■ A flexible mechanical and circuit structure (including pure optical modules, live modules, desktop and 1U structure) ■ All the performance meet the Bellcore GR*****-CORE requirements Application: ■ Analo
