1Product overview
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 (F-P)
or “Distributed Feedback” (DFB) 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, optionally a
DFB laser for medium and long haul applications, with 16 CWDM
wavelengths available. The open system platform of Network Electronics
flashlink®system allows easy interoperability with third party fiber optical
systems.
The electrical input(s) are equipped with a multi rate cable equaliser(s)
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 (on HW version 1, only one can be used for DVB-ASI).
Optionally, a built-in change-over can switch to the standby input if the main
input experiences a loss of signal (version 2 hardware only).

2.7 Connector module
HD-EO version 1 uses the connector module: SDI-C1 (Rev.1 or later, figure 3).
Figure 3: HD-EO (version 1) backplane.
HD-EO version 2 uses the connector module HD-EO-2-C1 (figure 4).
Figure 4: HD-EO (version 2) backplane.
The connector module is mounted at the rear of the sub-rack.
In typical use an HD-EO / HD-OE module at each end will be used. The
electrical input signal is connected to the IN1 or IN2 (DIGITAL INPUT for
version 1) BNC on the transmitting HD-EO, and the electrical output is
connected to an output BNC on the receiving HD-OE (see HD-OE manual for
possible configurations). The fibre cable is connected to the OPTICAL ports on
HD-EO and HD-OE.
Please note that some output BNCs on HD-OE might carry an inverted signal,
so formats like DVB-ASI can not be used on these outputs.

will be performed. This mode may be used for non-standard or unsupported bit rates over shorter
distances and up to 1 Gbps.

3Configuration
3.1 Version 2 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. Look at the labels beside the 8 dip switches
near the release handle in order to find out what hardware version of HD-EO
you have. If the labels match the table below, you have version 2. If they
match the table in chapter 3.2, you have version 1.
