1 Product overview
The flashlink®SDI-OE-2 is a dual multi bit-rate optical to electrical converter
module providing high performance media conversion for various signal
formats from 19.4Mbps up to 540Mbps. This state of the art unit offers a high
sensitivity PIN diode technology with long wavelength on single mode fiber.
Unmatched signal accuracy, even in critical applications with pathological
signal patterns makes the HD-OE-2 the first choice for all optical transport
demands.
The SDI-OE-2 can transport all SD signal formats in addition to DVB-ASI and
SMPTE 310. It performs optical refreshing and signal reclocking, which is
selectable on application. The optical input comes with a sophisticated PIN
diode with a sensitivity typically better than –30dBm operating in the 2nd and
3rd optical windows. The open system platform of Network Electronics
flashlink®system allows easy interoperability with third party fiber optical
systems.
The two independent electrical outputs are equipped with a distribution
amplifier where 2 outputs reduces the need for additional DA’s.

3 Configuration
3.1 Format configuration
The SDI-OE-2 can support a number of different broadcast formats. The
correct configuration can either be set with a DIP switch or with the GYDA
Control System. The layout of SDI-OE-2 is shown in the drawing below with
the DIP switch to the upper left position.
Figure 2: SDI-OE-2 board layout.
DIP switch configuration must be set according to the table below:

4 Connector module
The SDI-OE-2 has a dedicated connector module: HD-EO-2-C1. This module
is mounted at the rear of the sub-rack. The module is shown in the figure
below.
Figure 5: Connector module for SDI-OE-2.
In typical use a SDI-EO-2 / SDI-OE-2 module at each end will be used. Two
channels simultaneously can be converted from optical to electrical channels
The electrical input signal is connected to the INx input on the transmitting
SDI-EO-2, and the electrical output is connected to corresponding the OUTx+
or OUTx- output BNC on the receiving SDI-OE-2. The fibre cable is connected
to the corresponding optical port (OPT1 uses IN1/OUT1- and OUT1+ and
OPT2 uses IN2/OUT2- and OUT2+).
4.1 Mounting the connector module
The details of how the connector module is mounted, is found in the user
manual for the sub-rack frame FR-2RU-10-2.
This manual is also available from our web site:

formats. The table below shows which signal formats are supported on the
selected terminals.

∗SDI-OE-2 has a “Transparent mode”. In this mode all reclockers are switched off and no jitter attenuation
will be performed. This mode may be used for non-standard or unsupported bit rates over shorter
distances and up to 1 Gbps.

5 Module status
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional).
2. GPI at the rear of the sub-rack.
3. LED’s at the front of the sub-rack.
Of these three, the GPI and the LED’s are mounted on the module itself,
whereas the GYDA System Controller is a separate module giving detailed
information on the card status. The functions of the GPI and the LED’s are
described in sections 5.1 and 5.2. The GYDA controller is described in a
separate user manual.
5.1 GPI Alarm – Module status outputs
These outputs can be used for wiring up alarms for third party control systems.
The GPI outputs are open collector outputs, sinking to ground when an alarm
is triggered. The GPI connector is shown in figure below.
