• The Optical Power Budget data fit Mulit-mode(62.5/125 μm),Single-Mode(9/125 μm).
• When using 50/125 μm multimode fiber, subtract 3 dB from the optical power budget.
• Optical transmission distance is limited to optical loss of the fiber and any additional loss introduced by connectors, splices and patch panels.
• Maximum transmission distance is also limited by fiber bandwidth.
• Power adapter is manufactured by third party and is supplied with fitted screw-terminal output cables.Power adapter included (for standalone) US, European, UK or Australian power plug.
• Please feel free to consult factory for any special requirement and customization.
