Instruction Manual – DXLink Fiber Transmitters and Receivers
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 29).
Device Types / Cable Types / Cable Runs
The type of DXLink Fiber device determines 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.
DXLink Fiber, Duplex multimode and single mode transceivers support bidirectional communication (Bidirectional
Mode) or unidirectional communication (Unidirectional and Data Link-lost Mode). DXLink Fiber, Simplex multimode
and single mode transceivers only support unidirectional communication.
Bidirectional Mode Communication
Bidirectional communication over DXLink Fiber includes transmission of digital video and audio, native NetLinx
control (IR and RS-232), USB keyboard and mouse, and Ethernet (100 Mbps).
Unidirectional Mode and Data Link-lost Mode Communication
Unidirectional and Data Link-lost communication over DXLink Fiber includes transmission of digital video and audio.
While native NetLinx control (IR and RS-232) is not supported over fiber, units can provide this support when they are
connected to a LAN via their ICS LAN 10/100 connector (see “Unidirectional Mode LAN Configuration” on page 60).
