Chapter 3: Safety and equipment care This chapter contains important safety and regulatory information. Read this section before you install Small Form Factor Pluggable (SFP) and Small Form Factor Pluggable Plus (SFP+). Fiber optic equipment care Use the information in this section to properly maintain and care for fiber optic equipment. Transceivers are static sensitive. Dust contamination can reduce the performance of optical parts in transceivers.
Safety and equipment care • Do not stand on fiber optic cable; keep the cable off the floor. • Do not pull fiber optic cable harder than you do a cable containing copper wire of comparable size. • Do not allow a static load of more than a few pounds on a section of the cable. • Place protective caps on fiber optic connectors that are not in use. • Store unused fiber optic patch cables in a cabinet, on a cable rack, or flat on a shelf.
Fiber optic equipment care Cletop, to clean the connector. A reel cleaner is a good choice to ensure that no dust contaminates the connector. • If the connector is visibly dirty or you suspect contamination by chemicals (for example, matching gel), use high-quality alcohol and canned air to clean the connector. This method is the most thorough cleaning method. In some cases, a reel cleaner can suffice.
Safety and equipment care Important: Do not let the IPA evaporate; wipe it dry immediately. Alcohols can leave a residue that is difficult to remove. 4. Dry the connector surfaces by applying canned air. 5. Inspect the connector to ensure it is clean and undamaged. To prevent contamination, do not touch the connector surfaces after cleaning; and cover connectors with dust caps if they are not in use.
Fiber optic equipment care 3. Gently wipe the cylindrical and end-face surfaces of both ferrules using a tissue saturated with optical-grade isopropyl alcohol. 4. Gently wipe the cylindrical and end-face surfaces with a dry tissue. Important: Do not let the IPA evaporate; wipe it dry immediately. Alcohols can leave a residue that is difficult to remove. 5. Blow dry the connector surfaces with canned air. 6. Inspect the connector to ensure it is clean and undamaged. 7.
Safety and equipment care Important: Do not let the IPA evaporate; wipe it dry immediately. Alcohols can leave a residue that is difficult to remove. 4. Remove lint by blowing compressed air into the optical port. 5. Reconnect the optical connector and check for proper function. If you do not reinstall the connector, use a protective cap. If problems persist, ensure that the connector or receptacle is free from damage.
Chapter 4: SFP This chapter provides installation procedures and specifications for Small Form Factor Pluggable (SFP) transceivers. SFP transceivers This section describes how to select and install Small Form Factor Pluggable (SFP) transceivers. Use SFP transceivers to connect a device motherboard to a fiber optic or unshielded twisted pair network cable. The SFP transceivers described in this chapter provide Ethernet at 1 gigabit per second (Gbps).
SFP 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. Not all SFP transceivers or products support DDM.

SFP Procedure 1. Remove the SFP from its protective packaging. 2. Grasp the SFP transceiver between your thumb and forefinger. 3. Insert the device into the port on the module. Depending on the module type, you must insert some SFP transceivers into the port with the bail facing up and some SFP transceivers with the bail facing down. Warning: Risk of equipment damage SFP transceivers are keyed to prevent incorrect insertion.
SFP specifications Before you begin • Wear an antistatic wrist strap. Danger: Risk of eye injury by laser Fiber optic equipment can emit laser or infrared light that can injure your eyes. Never look into an optical fiber or connector port. Always assume that fiber optic cables connect to a light source. Electrostatic alert: ESD can damage electronic circuits. Do not touch electronic hardware unless you wear a grounding wrist strap or other static-dissipating device. Procedure 1.

SFP+ transceivers 3. Use the following job aid to determine the appropriate SFP+ transceiver or cable for your application. Job aid SFP+ transceivers are hot-swappable input and output enhancement components that allow 10 gigabit connections. All Avaya SFP+ transceivers use Lucent connectors (LC) to provide precision keying and low interface losses. The following table lists and describes the Avaya SFP+ models.
SFP+ Installing an SFP+ Install an SFP+ transceiver to provide a 10–gigabit Ethernet interface between the device and other network devices. Before you begin Important: Do not install an SFP+ transceiver in an SFP slot. The two transceivers look the same but function differently. • Verify that the SFP+ transceiver is the correct model for your network configuration. • Before you install the optical connector, ensure it is clean.
SFP+ transceivers Job aid Depending on the transceiver manufacturer, the SFP+ transceiver uses bail-latch type of locking and extractor mechanism. The following figure shows typical mechanism used on SFP+ transceivers; other locking and extractor mechanisms exist. SFP+ transceivers are similar to SFP transceivers in physical appearance. In the following figure, the SFP+ transceiver still contains the bore plug. Pull the bail to release the device.
SFP+ 4. Affix dust covers over the fiber optic bore and connector. 5. Store the SFP+ transceiver in a safe place until needed. Important: If you discard the SFP+ transceiver, dispose of it according to all national laws and regulations.
