3 If the media is optical fiber, determine any wavelength restrictions or
requirements.
To expand available bandwidth on a common optical fiber, use
CWDM SFPs.
4 Determine if digital diagnostic monitoring (DDM) is required.
Not all SFPs or products support DDM.
5 Use the following job aids to determine the appropriate SFP for your
application.

The following table describes the reach provided by various SFPs. This
table is informational only—not all Nortel ethernet switching and routing
products support all the SFPs listed here.

SFPs and common applications
SFP model Common application
1000BASE-T Lowest-cost Gigabit Ethernet solution. Up to 100 m reach over Category 5
(CAT5) unshielded twisted pair (UTP).
1000BASE-SX Well-suited for campus local area networks (LAN) and intrabuilding links.
Up to 275 or 550 m reach (fiber-dependent) over a fiber pair.
1000BASE-LX Up to 10 km reach over a single mode fiber (SMF) pair. Up to 550 m reach
over a multimode fiber (MMF) pair.
1000BASE-XD Up to 40 km reach over a single mode fiber pair.
1000BASE-ZX Up to 70 km reach over a single mode fiber pair.
1000BASE-BX Up to 10 km or 40 km reach. Bidirectional over one single mode fiber.
1000BASE-EX Up to 120 km reach over a single mode fiber pair.
Procedure job aid: SFP models without DDI support
SFPs are hot-swappable input/output enhancement components designed
for use with Nortel products to allow Gigabit Ethernet ports to link with other
Gigabit Ethernet ports over various media types.
The SFPs described in this section do not have Digital Diagnostic Interface
capability, and are RoHS -E5 compliant.
