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.

.
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.
Common application
Provides 1.544 Mbit/s connectivity with up to 2874 m reach over 22 AWG
cable. The distance may be reduced when 24 AWG UTP CAT5/5E cable
is used. Applications include connecting remote LANs and providing
transparent LAN services over leased lines.
Provides 100 Mbit/s LAN services with up to 2 km reach.
Lowest-cost Gigabit Ethernet solution. Up to 100 m reach over Category 5
(CAT5) unshielded twisted pair (UTP).
Well-suited for campus local area networks (LAN) and intrabuilding links.
Up to 275 or 550 m reach (fiber-dependent) over a fiber pair.
Up to 10 km reach over a single mode fiber (SMF) pair. Up to 550 m reach
over a multimode fiber (MMF) pair.
Up to 40 km reach over a single mode fiber pair.
Up to 70 km reach over a single mode fiber pair.
