Chapter 5: Small Form Factor Pluggable Transceivers; Selecting An Sfp - Avaya 8800 Series Installation Manual

Chapter 5: Small form factor pluggable
This section 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 section provide Ethernet at 1 gigabit per second (Gb/s).
You can use the Power Management function to monitor the power usage of modules containing SFPs.
For more information, see Avaya Ethernet Routing Switch 8800/8600 Administration, NN46205-605.
For information about the minimum software versions required to support the hardware described in this
document, see Avaya Ethernet Routing Switch 8800/8600 Administration, NN46205-605.

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.
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).

transceivers
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.
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.
To expand available bandwidth on a common optical fiber, use Coarse Wavelength
Division Multiplexing (CWDM) SFPs.
Not all SFPs or products support DDM.
