Instruction Manual – DXLink Fiber Transmitters and Receivers
OSHA Directive
The
OSHA Technical Manual
(at https://www.osha.gov/dts/osta/otm/otm_iii/otm_iii_6.html) under “VI. Control
Measures and Safety Programs” states: “Direct exposure on the eye by a beam of laser light should always be avoided
with any laser, no matter how low the power.”
Transceiver Disposal
Important:
If disposal of transceivers is necessary, dispose of them as mandated by your area or country
guidelines.
Multimode SFP+ Fiber Optic Transceiver
Multimode SFP+ fiber optic transceivers are used in the DXLink Fiber units specified in the table at the top of the
previous page. Depending on the transceiver model, it will have a latch that is black 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 traverse the optic core. Multimode fiber optic cable has a significantly larger optical core (which results in a higher
dispersion rate) and results in comparative shorter distance optical runs than the single mode cable.
Single Mode SFP+ Fiber Optic Transceiver
Single mode SFP+ fiber optic transceivers are used in the DXLink Fiber units specified in the table at the top of the
previous page. 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.
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 below).
