Replacing an SFP+ Fiber Optic Transceiver

This section applies to replacement of SFP+ fiber optic transceivers for DXLink Fiber boards (and DXLink Fiber units).
IMPORTANT: Compatibility between hardware requires matching model types: multimode to multimode and single mode
to single mode.

Items Required

Replacement SFP+ fiber optic transceiver

DXLink Fiber Board or DXLink Fiber unit

ESD wristband and cord with alligator clip

ESD shielded bag for storage of removed transceiver


Multimode SFP+ Fiber Optic Transceiver

The multimode SFP+ fiber optic transceiver is used on DXLink Fiber, Duplex and Simplex Boards. Depending on the
transceiver model, it will have a black latch or a black label on the latch top with white triangles showing data flow
direction (FIG. 60).

The multimode SFP+ fiber optic transceiver requires multimode fiber optic cable, which allows numerous optical waves to
transverse the optic core. Multimode fiber optic cable has a significantly larger optical core (and therefore a higher
dispersion rate) and results in comparative shorter distance runs than the single mode cable.

Single Mode SFP+ Fiber Optic Transceiver

The single mode SFP+ fiber optic transceiver is used on DXLink Fiber, Duplex and Simplex Boards. Depending on the
transceiver model, it will have a bright blue latch or a blue label on the latch top with white triangles showing data flow
direction (FIG. 61).
FIG. 61
Multimode SFP+ fiber optic transceiver (model with black label on latch top shown)
The single mode SFP+ fiber optic transceiver requires single mode fiber optic cable, which allows a single optical wave to
traverse through the optic core. Single mode fiber optic cable has a significantly smaller diameter optical core than
multimode fiber optic cable and is generally associated with longer distance transport capabilities.

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.
ESD WARNING:
touching any internal Enova DGX materials. Use an ESD wristband and cord with an alligator clip attached to a good ground source.
NOTE: The process for removing and replacing transceivers is the same in DXLink Fiber Boards as it is in DXLink Fiber units
and the same for multimode transceivers (black latch) as it is for single mode transceivers (bright blue latch). The
photographs in the procedure below show a DXLink Fiber unit.
