3.4. Multimode Single Fiber Extender Concept
DVI-OPT-220Pro series extenders support multimode fiber optical interface to transmit digital A/V signals.
For more details about the supported cable extension see
section.
Port Diagram of Optical Interface
The Neutrik opticalCON DUO cable has two fiber channels, named channel
A
and channel
B
. Since Lightware
fiber extenders use only one fiber for signal transmission, the other fiber can be used by other optical devices.
The unused fiber channel is accessible by the break-out connector.
INFO: Red line shows the main direction of the video signal. The blue line represents the optical signal via
break-out connector, which direction is not specified.

Application Example of Break-out Connector
Using this feature, it is possible to transmit two different A/V signal from one transmitter pair to another
receiver pair with only one Neutrik opticalCON DUO cable. See the application example below.
Transmitter Unit (DVI-OPT-TX220-Pro)
The transmitter’s laser driver sends the signal through
Channel A
.
Channel B
is directly connected to the
break-out connector with a fiber optical cable inside
the unit. Any optical signal can be transferred through
this channel in any direction.
Receiver Unit (DVI-OPT-RX220-Pro)
The receiver’s laser sensor gets the signal through
Channel B
.
Channel A
is directly connected to the
break-out connector with a fiber optical cable inside
the unit. Any optical signal can be transferred through
this channel in any direction.
