Chapter 5: Small form factor pluggable
transceivers
This chapter describes how to select and install small form factor pluggable (SFP) transceivers.
Use an SFP to connect a device motherboard to a fiber optic or unshielded twisted pair network cable.
The SFPs described in this chapter provide Ethernet at 1 gigabit per second (Gb/s).
The Avaya VSP 4000 supports SFPs on fiber ports 47 and 48.
Selecting an SFP
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 steps
1. Determine the required reach.
Depending on the product, SFPs are available for cable distances of up to 100
meters (m), 550 m, 10 kilometers (km), 40 km, 70 km, and 120 km.
2. Determine the required media and connector type.
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), MT-RJ, and RJ-45.
3. If the media is optical fiber, determine wavelength restrictions or requirements.
To expand available bandwidth on a common optical fiber, use Coarse Wavelength
Division Multiplexing (CWDM) SFPs.
4. Determine if you need digital diagnostic monitoring (DDM).
Not all SFPs or products support DDM.
5. Use the following job aids to determine the appropriate SFP for your application.
