1. General
The flashlink HD-EO is a multi bit-rate electrical to optical converter module providing high
performance media conversion for various signal formats from 19.4Mbps up to 1485Mbps. This state of
the art unit offers Fabry-Perot laser technology with long wavelength on single mode fiber. Unmatched
signal accuracy, even in critical applications with pathological signal patterns makes the HD-EO the first
choice for all optical transport demands.
The HD-EO can transport all HD and SD signal formats in addition to DVB-ASI and SMPTE 310. It can
also perform signal reclocking, which is selectable on application. The optical output comes with a
sophisticated 1310nm F-P laser covering the demands of short and medium haul applications. The open
system platform of Network Electronics flashlink system allows easy interoperability with third party
fiber optical systems.
The electrical input is equipped with a multi rate cable equaliser providing an equalisation of typically
100m of high quality coax cable at 1485Mbps. A distribution amplifier with 2 outputs reduces the need
for additional DA’s (for DVB-ASI only one can be used).

3. Format Configuration
The HD-EO 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 is shown in the drawing
below with the DIP switch to the upper left position.
Figure 2 - HD-EO-13T board layout.
DIP switch configuration must be set according to the table below:
Switch # Label Function DIP=ON Function DIP=OFF Comment
1D/B Not in use Not in use Always in broadcast mode
2E/O Not in use Not in use Always E to O mode
3RCL Reclocker ON Reclocker Bypass Reclocker mode
4EQ Cable equaliser ON Cable equaliser Bypass Equaliser mode
5ASI DVB-ASI Reclocker

6GBE Not in use Not in use
7622 Not in use Not in use
8OVR Override GYDA control

GYDA
All DIP switches are off when pointing towards the release handle.
All clock rates for HD-SDI, SDI and DVB-ASI are automatically configured by the module itself.

4. Connector module
The HD-EO has a dedicated connector module: SDI-C1 (Rev.1 or later). This module is mounted at the
rear of the sub-rack. The module is shown in figure 3.
Figure 3 - Overview of the SDI-C1 connector module
In typical use a HD-EO / HD-OE module at each end will be used. The electrical input signal is connected
to the DIGITAL INPUT BNC on the transmitting HD-EO, and the electrical output is connected to the
DIGITAL OUTPUT 1 or DIGITAL OUTPUT 2 BNC on the receiving HD-OE. The fiber cable is
connected to the OPTICAL ports on HD-EO and HD-OE. Please note that DIGITAL OUTPUT 2 has an
inverted signal, 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.

Output
* HD-EO 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.
