There may be -- a separate VOA per channel, one VOA per band of wavelengths, -- or one VOA for the pass through wavelengths. -- -- VOA modules are also often used before terminating optical -- wavelengths at optical receivers, in order to avoid receiver -- saturation. -- -- The VOAs may be present on various modules within the network -- element, for example, on an Optical Add/Drop Multiplexer -- (OADM) module, on the same module as an optical transceiver, -- or on a separate module of its own. -- RevDate -- 200205070000Z -- RevDescr -- The initial revision of this MIB. cVoaMIBObjects OBJECT IDENTIFIER ::= { ciscoVoaMIB 1 } cVoaBaseGroup OBJECT IDENTIFIER ::= { cVoaMIBObjects 1 } cVoaMIBConformance OBJECT IDENTIFIER ::= { ciscoVoaMIB 3 } cVoaMIBCompliances OBJECT IDENTIFIER ::= { cVoaMIBConformance 1 } cVoaMIBGroups OBJECT IDENTIFIER ::= { cVoaMIBConformance 2 } OpticalPowerInDbm ::= INTEGER(-1000|-400..250) -- TEXTUAL-CONVENTION -- Status -- mandatory -- Descr -- An integer value that gives the optical power level in 1/10ths -- of dBm. -- Example: The value -300 represents a power level of -30.0 dBm. -- -- The distinguished value of '-1000' indicates that the object -- has not yet been initialized.

When the mode is set to 'manual', the attenuation level is configured manually, by setting the desired attenuation level in the cVoaAttenuation object. The cVoaDesiredPower object does not apply in this case. When the mode is set to 'automatic', the attenuation level is continuously adjusted to maintain a desired power level, after attenuation. The desired optical power level after attenuation is configured using the cVoaDesiredPower object. The cVoaAttenuation object cannot be configured in this case, but it indicates the attenuation level derived from the desired power level. The automatic mode of controlling attenuation should not be used when the monitored power level includes multiple wavelengths, since the power level monitor cannot distinguish between a decrease in power across all wavelengths, versus a loss of power of some but not all wavelengths. If some but not all wavelengths go down, this would cause the attenuation level to be automatically decreased, leading to an increase in the power level of the remaining wavelengths." ::= { cVoaEntry 2 } cVoaAttenuation OBJECT-TYPE SYNTAX OpticalAttenInDb -- Rsyntax INTEGER(0..400) ACCESS read-write STATUS mandatory DESCRIPTION "This object indicates the attenuation level applied at the interface.
