This object indicates the type of an optical interface, when the type is not specified in the ifType object in the IF-MIB, i.e., when the ifType object is set to 'other'. The value 'opticalTransponder' represents an optoelectronic interface that relays signals of various physical layer protocols. The interface may be capable of pulse shaping and retiming. The interface may be capable of monitoring various physical layer protocols. The interface may emit signals that are colored (e.g. one channel in a DWDM system) or uncolored (i.e., for single channel interfaces). The value 'wdmTransport' indicates an optical interface that carries multiple wavelengths. The value 'wdmChannel' indicates an interface sub-layer above 'wdmTransport' representing a single wavelength. The value 'wdmChannelGroup' indicates an interface sub-layer above 'wdmTransport' representing a wavelength division multiplexed group of wavelengths. The value 'wavelengthTransport' indicates an optical interface that carries a single wavelength. The value 'ethernetPhy' indicates an interface that implements the physical layer of the Ethernet protocol. The value 'esconPhy' indicates an interface that implements the physical layer of ESCON. The value 'gigabitPhy' indicates an interface that supports the physical layers of both Gigabit Ethernet and Fibre Channel. The value 'twoGigabitPhy' indicates an interface that supports the physical layer of 1x and 2x Fibre Channel. The value 'sonetPhy' indicates an interface that carries the trunk side traffic of eight port multirate muxponder The value 'multiRate' indicates an interface that supports client protocols of eight port multirate muxponder .
