Syntax

Release Information

Statement introduced in Junos OS Release 17.1R1.

Description

Displays the status information about a particular erbium-doped fiber amplifier (EDFA) for the optical inline amplifier (ILA). There are two EDFAs in the optical ILA: one is responsible for A to B direction (for example, east to west) and is called EDFA-A-B; the other one is responsible for B to A direction (for example, west to east) and is called EDFA-B-A. Information is shown for the EDFA-A-B and EDFA-B-A.

Options

fpc-slot—Slot number of the FPC or PIC in which the integrated photonic line card (IPLC) module resides.

ila-number—The number assigned to the optical ILA.

Table 1: show chassis fpc optical-properties amplifier-chain ila edfa Output Fields

Field Name	Field Description
edfaIndex	Index of the EDFA in the optical ILA (1 or 2).
Manufacture information	Displays the EDFA’s manufacturing information.
edfaModuleType	Name of the module.
edfaPartNumber	EDFA part number.
edfaSerialNumber	EDFA serial number.
edfaMfgDate	Name of manufacturer.
edfaCaliDate	Date of calibration.
edfaFirmwareVer	Firmware version.
edfaHardwareVer	Hardware version for the EDFA.
edfaMode	The EDFA’s workmode.
edfaGainSetting (0.01dBm)	Displays the EDFA’s gain setting in automatic-gain control (AGC) mode. AGC is a mode of operation in which the optical ILA adjusts it’s gain to compensate for the preceding span loss.
edfaTilt (0.01dBm)	Displays the EDFA tilt.
edfaWorkingStatus	The EDFA’s status. The status is Normal, Output Disabled, or Standby. The Automatic Power Reduction (APR) status is APR activated or APR deactivated.
edfaAprEnable	Displays whether the APR is enabled or disabled.
edfaWorkRange	Displays the EDFA’s gain working range, it is Low Gain or High Gain.
edfaActualGain (0.01dBm)	Displays the EDFA’s actual gain in response to the EDFA’s gain setting target.
edfaCaseTemperature (C)	The EDFA’s case temperature. Case temperature measures the temperature inside the case.
edfaPumpTemperature (C)	The EDFA’s pump temperature. Pump temperature is the set operating temperature of the pump.
edfaAse (0.01dBm)	The EDFA’s amplified spontaneous emission (ASE) in dBm.
edfaUpstreamOutputPower (0.01dBm)	The output power of the optical ILA preceding the previous optical span.
edfaInputPower (0.01dBm)	The input optical power. The unit is dBm.
edfaOutputPower (0.01dBm)	The output optical power. The unit is dBm.
edfaDownstreamInputPower (0.01dBm)	Input power of the optical ILA following the next optical span.
edfaInputLOSThreshold (0.01dBm)	Displays the set threshold for the minimum input power to the EDFA. If the received power is less than this threshold, the EDFA declares loss of signal (LOS). The unit is dBm.
edfaOutputLOSThreshold (0.01dBm)	Displays the set threshold for the minimum output power to the EDFA. If the transmitted power is less than this threshold, the EDFA declares LOS. The unit is dBm.
