20 Small form factor pluggable transceivers
Possible media include CAT5, single mode fiber, and multimode
fiber. Possible connectors include LC (Lucent optical connector),
MT-RJ, and RJ-45.
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.

Procedure job aid: SFPs and common applications
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 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
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.
