Remark
•The Optical Power Budget fit Multi-mode(62.5/125m),Single-Mode(9/125 m).
•When using 50/125 m 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 for stand-alone units is manufactured by third party .Power adapter included US, European, UK or Australian power plug.
