Device Description
Congratulations on your purchase of a DD2FR-FX Optical Digital Network Device with Cat5 based SANE, MADI,
video, Ethernet and data interfaces. The DD2FR-FX manual will quickly demonstrate the advantages of the
device and help to ease your day-to-day workload in a professional audio-visual environment.
The DD2FR-FX is a digital I/O unit and interface to the OPTOCORE

and SANE

DIGITAL NETWORK SYSTEM.
The unit provides two SC single/multimode optical MADI input and two SC single/multimode optical MADI output
ports, allowing the transmission of up to 128 input and 128 output digital audio channels. Device can operate in
sample rates up to 192 kHz (sample rates above 96 kHz are available upon request). Each MADI port can be
adjusted by OPTOCORE CONTROL software to handle different formats according to the standards AES10-
1991/AES10-2003. SC multimode optical cables shall be used at the MADI ports. The device is perfectly suitable
for 3
rd
party equipment integration, especially with Soundcraft, Studer, Lawo and SSL digital consoles.
Redundant fibre Optocore connections can be established using the two provided SFP-based LC multimode or
singlemode optical LINK-interfaces. The dual redundant ring structure provides maximum safety in a network with
an outstanding low latency. It facilitates the use of the advantages of fibre optical transmission in all sorts of
temporary and permanent applications, especially when long distance connections and high-quality audio are
required.
The DD2FR-FX enables connectivity to the SANE network via RJ45 ports. It is possible to use SANE as a Cat5
based cost-efficient extension to the optical core system. SANE ports may be used as point-to-point MADI over
Cat5 or as a bridge interface between SANE and OPTOCORE, providing in total up to 128 input and 128 output
additional channels.
Two built-in Ethernet ports can be used to establish 100Mbit Ethernet LAN through the OPTOCORE and SANE
networks. The DD2FR-FX together with R-Series devices, YG2 and DD6NE behaves like one 100Mbit Ethernet
switch. SANE ports can be used for Ethernet transport as well, so up to four ports can be used to provide Local
Ethernet connection via single DD2FR-FX.
The DD2FR-FX provides both word clock input and output. It includes also bi-directional composite video
interfaces. Additionally four RS485 ports allow the transport of a wide range of standards such as RS422, DMX,
MIDI, and CAN-Bus (bi-directional, requires special firmware version). In addition to the audio signals, video and
data signals are transmitted through the common fibre connection. The dual power supply unit, with automatic
switchover, permits a redundant power supply and safeguards against malfunctions in the event of a power
supply failure.
The DD2FR-FX is the perfect I/O interface for a wide range of professional audio devices with MADI inputs and
outputs such as digital consoles and I/O systems. The high number of channels exchanged by one DD2FR-FX
makes it the ideal and most cost effective interface for digital console systems. The number of input channels can
be defined in groups of eight by the OPTOCORE CONTROL software. Only this number of channels is allocated
for transmission via fibre optical connection. This keeps the system highly flexible in order to build the network
exactly suiting the application needs. A DD2FR-FX, for example, can transmit 128 channels to a digital console
system from various Optocore devices such as DD32R-FX, X6R-FX or V3R-TP. If only eight return channels from
the console are required, only those eight channels instead of 128 inputs can be received at the DD2FR-FX and
transmitted via fibre optical connection, leaving the other channels to be shared with the other network devices.
Networks with several DD2FR-FX and other Optocore devices allow the transport of a huge amount of digital
signals, e.g. 768 audio channels with a sample rate of 48 kHz, 32 RS485 channels and three video channels.
Depending on the type of fibre optic transceiver, distances from 700 m up to 120 km can be covered.
The dual optical interfaces with data transfer rates up to 2 Gbps are equipped with LC-connectors, commonly
used and absolutely reliable in permanent installations. For rough applications such as touring and live
productions the 1U OptoCon panel, with rugged and secure fibre optic connectors can be added to the rack.
All Optocore devices are designed and built using the latest programmable microprocessors and FPGA (field
Please note:
Fiber MADI ports on DD2FR-FX are equipped with special fiber transceivers which
support both singlemode and multimode connectivity. Please use multimode cable in
