Procedure job aid: SFP models with DDI support

Digital Diagnostic Monitoring (DDM) allows the Metro Ethernet Routing
Switch 8600 to monitor SFP laser operating characteristics. Metro Ethernet
Routing Switch 8600 support for Digital Diagnostic Interfaces (DDI-an
interface that supports DDM) involves data collection and alarm and warning
monitoring. Static data collection includes the SFP vendor information, DDI
support information, and DDI alarm and warning threshold values. Dynamic
data collection includes temperature, supply voltage, laser bias current,
transmit power, and receive power. DDM works at any time during active
laser operation without affecting data traffic.
The warning and alarm status bits are only checked during initialization
and during requests for dynamic data. If an alarm or warning is asserted
or cleared, a message is logged and a trap is generated. DDM warning
and alarm messages are mapped into WARNING and FATAL message
categories for system logging purposes. If an alarm or warning is generated,
the software does not automatically shut down the port.
CWDM SFPs are also supported. CWDM SFPs are designed to support
high-speed data communications. A CWDM system uses a grid of
wavelengths to provide multiple channels for both ring and point-to-point
configurations. All components are color-coded by wavelength.
