Detailed Description

Introduction: Dynamic Variable Optical Attenuator (DVOA) is the important device for realizing full optical network power in the regulation and it based on the micro electrical mechanical system. DVOA can realize the long-distance control of optical network. The main applications of DVOA are: light path power balance, channel transmission equilibrium, light automatic gain regulation, optic receiver protection etc. Our company’s DVOA products use MEMS chips and unique optical design which make products smaller and the cost lower. Meanwhile, our products have fast reaction speed, high reliability and stability. Features High reliability High stability Low insertion loss High reaction speed Small volume High light transmission power Applications Light path power balance Channel transmission equilibrium Light automatic gain regulation Optic receiver protection Optic path open/broken Specifications Wavelength C band 1525 -1575 nm 1525 -1575 nm L band 1570 -1610 nm 1570 -1610 nm Parameters Normally open Normally closed Typical maximum Typical maxim Attenuator range 0~25 dB 0~60 dB 0~25dB 0~60B Insertion loss 0.5 dB 0.8 dB 0.7 dB 0.9 dB Response time 20 ms 20 ms Transmission power 24 dBm 300mW 24 dBm 300W Device power dissipation 120 mW 150 mW 120 mW 150 mW Drive impedance - 240 Ω - 200 Ω Wavelength flatness loss 10dB 0.2 dB 0.3 dB 0.3 dB 0.5 dB 20db 0.4 dB 0.5 dB 0.5 dB 0.7 dB Polarization dependant loss 10db 0.06 dB 0.1 dB 0.06 dB 0.1 dB 20db 0.12 dB 0.2 dB 0.12 dB 0.2 dB Temperature Independent loss -5 -75° C 0db 0.1 dB 0.3 dB 0.1 dB 0.3 dB 10db 0.2 dB 0.5 dB 0.5 dB 1.2 dB 20db 0.3 dB 0.7 dB 0.5 dB 1.5 dB Repeatability - 0.1 dB - 0.1 dB Return loss - 45 dB - 45 dB Drive voltage - 6V DC - 5V DC Operating temperature -5 -75° C -5 -75° C Storage temperature -40 -85° C -40 -85° C
