Instruction Manual – DXLink Fiber Transmitters and Receivers
Appendix G – Fiber Transceiver Replacement
Applicability Notice
This appendix pertains to replacement of SFP+ fiber optic transceivers for the DXLink Fiber Transmitters and Receivers
listed in the tables on page 12.
The process for removing and replacing transceivers is the same in Enova DGX DXLink Fiber Boards as it is in the
DXLink Fiber units and the same for multimode transceivers (black latch) as it is for single mode transceivers (bright
blue latch).
Items Required
Replacement SFP+ fiber optic transceiver
DXLink Fiber unit or DXLink Fiber board
ESD wristband and cord with alligator clip
ESD shielded bag for storage of removed transceiver
Important:
Compatibility between hardware requires matching model types: multimode to multimode and
single mode to single mode.
Important Information for Fiber Transceiver Replacement
Replacement transceivers
must
match those replaced: either multimode or single mode.
Adding or replacing SFP+ transceivers should be done only by personnel trained to handle ESD sensitive
parts and assemblies.
If disposal of transceivers is necessary, dispose of them as mandated by your area or country guidelines.
Note:
When fiber optic transceivers are not cabled (e.g., for shipping or storage), replace the dust plugs that
originally shipped with the product.

Warning:
DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive on page 15).
ESD Warning:
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are
properly grounded before touching any internal DXLink Fiber TX/RX materials. Use an ESD wristband and
cord with an alligator clip attached to a good ground source.
