SFP model Common application
1000BASE-T SFP Lowest-cost gigabit Ethernet solution. Up to 100 m reach over Category 5 (CAT5)
unshielded twisted pair (UTP).
1000BASE-SX SFP Well-suited for campus local area networks (LAN) and intrabuilding links. Up to
275 or 550 m reach (fiber-dependent) over a fiber pair.

SFP transceivers 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 ERS 3500 Series only checks warning and alarm status bits during initialization and during
requests for dynamic data. If the system asserts or clears an alarm or warning, the system logs a
