1Product overview
The flashlink®HD-EO-2 is a dual multi bit-rate electrical to optical converter
module providing high performance media conversion for various signal
formats from 19.4Mbps up to 1485Mbps. Unmatched signal accuracy, even
in critical applications with pathological signal patterns makes the HD-EO-2
the first choice for all optical transport demands.
The HD-EO-2 can transport all HD and SD signal formats in addition to DVB-
ASI and SMPTE 310. It performs electrical equalizing and signal reclocking,
both selectable on application. High quality optical transmitters using Fabry-
Perot lasers are suitable short and medium haul applications. The open system
platform of Network Electronics flashlink®system allows easy interoperability
with third party fiber optical systems.
The HD-EO-2 unit has also one electrical output for each channel, which
reduces the need for additional DA’s. The electrical input is equipped with a
multi rate cable equalizer providing an equalization of typically 100m of high
quality coax cable at 1485Mbps.

3Format configuration
The HD-EO-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 HD-EO-2 is shown in the drawing below with
the DIP switch to the upper left position.
Figure 2: HD-EO-2 board layout.
DIP switch configuration must be set according to the table below:

4Connector module
The HD-EO-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 3: Connector module for HD-EO-2.
In typical use a HD-EO-2 / HD-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
HD-EO-2, and the electrical output is connected to the corresponding OUTx+
or OUTx- output BNC on the receiving HD-OE-2. The fiber cable is connected
to the corresponding optical port (OPT1 uses IN1/OUT1- and OUT1+ and
OPT2 uses IN2/OUT2- and OUT2+). Please note that OUT1- and OUT2- have
inverted signal versions, so formats like DVB-ASI can not use be used on this
output.
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:

∗HD-EO-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.
