METHOD AND APPARATUS FOR OBTAINING AN OPTICAL POWER POWER LEVEL IN A PON

摘要

A method and apparatus for remotely obtaining an optical power level in a PON network is provided. An Element Management System (EMS) (12) transmits a Simple Network Management Protocol (SNMP) request message 44 to retrieve an optical power level from an Optical Network Unit (ONU) 20. After receiving the SNMP request message 44, an Optical Line Terminal (OLT) sends an optical power level request frame 50 to the ONU 20. The ONU 20 responds to the request 50 with an optical power level response frame 52 having an expected bit pattern that is used by an optics block 32(1) in the OLT 14 to calculate the upstream optical power level. The OLT 14 sends the calculated level to the EMS 12 in a SNMP response message 46.
