Small form factor pluggable transceivers

Possible media include CAT5, single mode fiber, and multimode
fiber. Possible connectors include LC (Lucent 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.

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.

Table 1
SFPs and common applications

SFP model

Common application

T1 Fast Ethernet to
T1 Remote Bridge

Provides 1.544 Mbit/s connectivity with up to 2874 m reach over 22
AWG cable. The distance may be reduced when common 24 AWG UTP
CAT5/5E cable is used. Applications include connecting remote LANs and
providing transparent LAN services over leased lines.

100BASE-FX

Provides 100 Mbit/s LAN services with up to 2 km reach.

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.

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.
