Instruction Manual – DXLink™ Fiber Transmitters and Receivers, Duplex
Product Notes
Fiber Optic Transceivers
The DXLink Fiber units use SFP+ fiber optic transceivers.* Fiber optic transceivers are self-contained modules that send
and receive optical signals over fiber cable. These fiber optic transceivers are either multimode or single mode and must
be wired with the corresponding cable type.
* SFP+ = enhanced small form-factor pluggable fiber optic transceiver rated at 10 Gbps transmission data rate.
Note:
The types of fiber optic transceivers used in DXLink Fiber units are referred to as “multimode” and
“single mode,” which indicate the maximum length of the fiber optic cable that can be used. In addition, the
Transmitters and Receivers support modes that can be determined during setup to handle the system
architecture, accommodate networking needs, and process video signals (see page 26).
Transceiver Types / Cable Types / Cable Runs
The type of SFP+ fiber optic transceiver helps determine the maximum length of cable runs possible. Cable quality is
also a determining factor.
All DXLink Fiber units are designed for transmission of an HDMI signal over fiber optic cable.
Both multimode and single mode transceivers on DXLink Fiber units support bidirectional communication
(Bidirectional Mode).
Bidirectional communication over DXLink Fiber includes transmission of the following:
Digital video and audio
Native NetLinx control
IR
RS-232
USB keyboard and mouse
Ethernet (100 Mbps)
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.

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).
