Replacing An Sfp+ Fiber Optic Transceiver - AMX DGX1600-ENC Hardware Reference Manual

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.
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.
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.

Important Information for Fiber Transceiver Replacement
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 118).
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: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded
before touching any internal Enova DGX materials. Use an ESD wristband and cord with an alligator clip attached to a good ground
source.
