Installation Instructions

Procedure
1. Determine the required reach.
Depending on the product, SFP transceivers 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 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) SFP transceivers.
4. Determine if you need digital diagnostic monitoring (DDM). DDM is enabled by default.
Job aid
SFP transceivers are hot-swappable input and output interface devices designed for use with
Extreme Networks products to allow Gigabit Ethernet ports to link with other Gigabit Ethernet ports
over various media types. SFP transceivers are devices that are used to connect pairs of ports
together over different media types, different distances, and at different price points.
The system also supports CWDM SFP transceivers. CWDM technology consolidates multiple
optical channels on a common optical fiber. CWDM uses multiple wavelengths to expand available
bandwidth.
CWDM SFP transceivers support high speed data communications for Metropolitan Area Networks
(MAN). The system uses a grid of eight CWDM optical wavelengths in both ring and point-to-point
configurations. All components are color-coded by wavelength.
Important:
• The attainable cable length can vary depending on the quality of the fiber optic cable used.
• Extreme Networks recommends using the transceivers documented in this document as
they have been through extensive qualification and testing. Extreme Networks is not
responsible for issues related to third party transceivers.
Installing an SFP
Install an SFP to provide an interface between the device and the network cable.
Before you begin
• Verify that the SFP is the correct model for your network configuration.
• Before you install the fiber, ensure that the connector is clean.
