DD8RP 7 / 15 rev. 1.0
Device Description
Congratulations on your purchase of a DD8RP Repeater / Media Converter Module. The DD8RP will quickly
convince you with its advantages and will facilitate your day-to-day work.
The DD8RP features two possible applications. It can operate as a repeater in an Optocore network, if distances
between devices are longer than 700 m and the standard multimode fiber cables are used. Or it can function as
media converter from multimode to monomode fiber connections and vice versa. The four repeaters / media
converters work protocol independent, they can be implemented in networks based on protocols such as Ethernet
as well. The unit is specially designed for low power consumption and provides a DC 12 V power supply. Battery
packs can supply the power, if no mains supply is available. This can immensely simplify outdoor applications.
The flexibility to use the DD8RP as repeater and converter is achieved by receptacles for SFP (Small Form-factor
Pluggable) optical transceivers. Eight receptacles form the four independent LINK interfaces; each LINK can
consist of two SFPs with dual LC type connectors. The function of a LINK as repeater or converter depends on
the implemented optical transceiver. This allows the configuration exactly appropriate for the application. E.g. one
LINK may extend the distance between two Optocore devices in an OPTOCORE®OPTICAL DIGITAL
NETWORK, while the other LINKs are used in totally different networks with non-Optocore protocols.
LEDs on the front give detailed information about the status and operating state of each LINK. They indicate if a
malfunction of any connection could influence the high quality data transmission.
Two power supplies with automatic switchover and individual connectors provide a high grade of safety. The first
power supply is for AC mains input including the unique 400 V tolerant Optocore design. An over-voltage-monitor
lights the OVP (Over Voltage Protection) status LED during an over voltage condition, simultaneously
suppressing the normal function of the device. The second power supply is for DC 12 V, equipped with a male 4-
pin connector. The DC power supply is compatible with battery packs, UPSs (Uninterruptible Power Supply) or
standard AC adapters.
Due to SMD production the DD8RP fulfills the demand of highest digital standards occupying only one rack unit of
a 19" rack. The FPGA (field programmable gate array) based concept of the internal logic circuitry permits
updating of the hardware via the units remote ports, ensuring a continual state-of-the-art device.

Device Details
LINK Ports
Four independent LINK ports provide receptacles for SFP optical transceivers. Each LINK can be equipped with
two SFPs with two LC-type connectors. The advantage of this concept is obvious. Each port holds the SFP
needed in the particular application. They can be changed without opening the device. The multimode full duplex
SFP transceiver (850nm) or monomode full duplex SFP transceiver (1300nm) can be purchased with the device
or can be ordered later.
The specification of the ports as A or B serves only for orientation. A dual LC cable with an input and output signal
connected to port A will be transferred to port B, either refreshed by the repeater or refreshed and converted to
another media type.
The DD8RP is not limited to be used in Optocore networks. It can operate in all sorts of networks no matter which
protocol is the base of the data transmission. The four LINKS are functioning totally independent; so one LINK
can serve in an Optocore network, the next one in a 1 Gbit-Ethernet and the others in completely different
networks.
Power Supply
The device is equipped with two power inputs and power supply units. If one power supply fails, due to
malfunction of the feeding power line or the power supply unit itself, the device will automatically switch over to
the other power supply unit.
One power supply unit operates with mains voltage of 100 ... 240 V and frequency of 50 … 60 Hz. Thus the
device can be used throughout the world without any adjustments or transformers.
The power supply unit is 400 VAC tolerant and protected against high current. The OVP (Over Voltage Protection)
LED on the front will indicate over voltage at > 300 V, simultaneously suppressing the normal function of the
device. When the OVP LED is lit, immediately disconnect the device from the power line to prevent any damage
to the device. The power input has a fuse, replaceable without opening the device.
Never bypass the fuse and only use the specified type.
Be aware that the switched-mode power supply operates with high voltages! Coming into contact with it
can lead to considerable electric shocks that may result in death! To prevent electric shocks do not
remove any covers!
The second power supply operates with 9-15 V / 1 A AC or DC. The low voltage can be provided by a wide range
of alternatives such as battery packs, UPSs (Uninterruptible Power Supply) or standard AC adapters. Specially in
temporary outdoor applications with long distances between devices, e.g. at a race course or a road race, this
simplifies the power supply. No generator or long power cables are necessary. The unit is specially designed for
low power consumption. A battery pack with a sufficient capacity can easily supply the required power.
Connectors and Cables
Optical Connection
The type of the optical fiber cables depends on the optical transceivers. The connectors are LC-type.
RS232-Connection
Shielded, standard 1-modem cable is sufficient for the RS232 port.
USB-Connection
For the USB-port use a standard PC/device cable.
Mains-Connection
For the power supply 1 standard power cords with IEC C13 socket can be used.
12V-Connector
For the power supply 2 a cable with 4 pole female XLR connector can be used.

DD8RP 10 / 15 rev. 1.0
Starting Up
The DD8RP is functioning independent of the format and structure of the connected devices. So no software
configuration is necessary, no ID has to be set and there is no limitation of the number of DD8RP implemented in
the network.
Hardware Connection
Each LINK is working autonomous. There are four separate repeaters or converters. To extend the distance
between two devices, e.g. two DD32E as shown in Fig. 1 and Fig. 2, one LINK interface of the DD8RP equipped
with the appropriate SFP optical transceivers is needed.
In Fig. 1 both receptacles of LINK 1 are equipped with multimode transceivers (orange). The LINK is functioning
as a repeater in order to extend the distance of a multimode connection. Port A of the LINK 1 is used as interface
to the DD32E with ID 2; port B as interface to the DD32E with ID 2.
Fig. 1: DD8RP between two DD32E, functioning as repeater in order to extend the distance of the
multimode connection.
The second example in Fig. 2 shows an application where the two DD8RP work as repeater and media converter.
The first DD8RP functions as a converter from multimode to monomode, the second DD8RP converts the signal
back to multimode. The ports of LINK 1 connected to the DD32E are equipped with multimode SFPs (orange).
The second ports of LINK 1 contain standard monomode SFPs (yellow) in order to enable distances up to 10 km.
SFPs for distances up to 70 km can be purchased on request. The converters refresh the signal as well. The full
cable length, 700 m between multimode transceivers and 10 km between monomode transceivers, is available.
