SFPs are hot-swappable input and output enhancement components that permit Gigabit
Ethernet ports to link with other Gigabit Ethernet ports over various media types.
The system also supports Coarse Wavelength Division Multiplexer (CWDM) SFPs. CWDM
technology consolidates multiple optical channels on a common optical fiber. CWDM uses
multiple wavelengths to expand available bandwidth.
CWDM SFPs support high speed data communications for Metropolitan Area Networks (MAN).
The system uses a grid of eight CWDM optical wavelengths in both ring and point-to-point
configurations. All components are color-coded by wavelength.
Important:
The attainable cable length can vary depending on the quality of the fiber optic cable
used.
Use Digital Diagnostic Monitoring (DDM) to monitor SFP laser operating characteristics.
Support for Digital Diagnostic Interfaces (DDI—an interface that supports DDM) involves data
collection and alarm and warning monitoring. Static data collection includes 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 during active laser operation without affecting data traffic.
The Virtual Services Platform 9000 only checks warning and alarm status bits during
initialization and during requests for dynamic data. If the system asserts or clears an alarm or
