Chapter 4: SFP transceivers

Selecting an SFP

About this task
Use an SFP transceiver to connect a device motherboard to a fiber optic or unshielded twisted
pair network cable. Select the appropriate transceiver to provide the required reach.
Procedure
1. Determine the required reach.
2. Determine the required media and connector type.
3. If the media is optical fiber, determine wavelength restrictions or requirements.
4. Determine if you need digital diagnostic monitoring (DDM).
5. Use the following job aid 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 Avaya products support all the SFPs listed here.
SFP model
1000BASE-T
Installing the SFP, SFP+, and XFP transceivers on Avaya ERS 3500 Series
Depending on the product, you can obtain SFPs for cable distances of up to 100
meters (m), 550 m, 10 kilometers (km), 40 km, 70 km, and 120 km.
You need fiber optic cable for a reach over 100 m.
Possible media include CAT5, single mode fiber, and multimode fiber. Possible
connectors include Lucent connector (LC) and RJ-45.
To expand available bandwidth on a common optical fiber, use Coarse Wavelength
Division Multiplexing (CWDM) SFPs.
Not all SFPs or products support DDM.
Lowest-cost gigabit Ethernet solution. Up to 100 m reach over
Category 5 (CAT5) unshielded twisted pair (UTP).
