24 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.

If the media is optical ﬁber, determine any wavelength restrictions or

requirements.

To expand available bandwidth on a common optical ﬁber, use

CWDM SFPs.

Determine if digital diagnostic monitoring (DDM) is required.

Not all SFPs or products support DDM.

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 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.
