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.

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.

4Module 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 Chapters 4.2 and 4.3. The GYDA controller is described in a
separate user manual.
4.1 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 figures below.

5Laser safety precautions
Guidelines to limit hazards from laser exposure.
All the available EO units in the flashlink®range include a laser.
Therefore this note on laser safety should be read thoroughly.
The lasers emit light at wavelengths around 1310 nm or 1550 nm. This means
that the human eye cannot see the beam, and the blink reflex can not protect
the eye. (The human eye can see light between 400 nm to 700 nm).
A laser beam can be harmful to the human eye (depending on laser power
and exposure time). Therefore:
!! BE CAREFUL WHEN CONNECTING / DISCONNECTING FIBER PIGTAILS (ENDS).
NEVER LOOK DIRECTLY INTO THE PIGTAIL OF THE LASER/FIBER.
NEVER USE MICROSCOPES, MAGNIFYING GLASSES OR EYE LOUPES TO LOOK
INTO A FIBER END.
USE LASER SAFETY GOGGLES BLOCKING LIGHT AT 1310 nm AND AT 1550 nm
Instruments exist to verify light output power: Power meters, IR-cards etc.
flashlink®features:
All the laser module cards in the flashlink®product range, are Class 1
laser products according to IEC 825-1 1993, and class I according to 21
CFR 1040.10 when used in normal operation.
More details can be found in the user manual for the FR-2RU-10-2 frame.
Maximum output power2: 5 mW.
Operating wavelengths: > 1270 nm.
2Maximum power is for safety analysis only and does not represent device performance.

Materials declaration and recycling information
Materials declaration
For product sold into China after 1st March 2007, we comply with the “Administrative
Measure on the Control of Pollution by Electronic Information Products”. In the first
stage of this legislation, content of six hazardous materials has to be declared. The table
below shows the required information.

O: Indicates that this toxic or hazardous substance contained in all of the homogeneous materials for
this part is below the limit requirement in SJ/T11363-2006.
X: Indicates that this toxic or hazardous substance contained in at least one of the homogeneous
materials used for this part is above the limit requirement in SJ/T11363-2006.
Environmentally-friendly use period
The manual must include a statement of the “environmentally friendly use period”.
This is defined as the period of normal use before any hazardous material is released to
the environment. The guidance on how the EFUP is to be calculated is not finalised at
the time of writing. See
http://www.aeanet.org/GovernmentAffairs/qfLeOpAaZXaMxqGjSFbEidSdPNtpT.pdf
for an unofficial translation of the draft guidance. For our own products, Network
Electronics has chosen to use the 50 year figure recommended in this draft regulation.
Network Electronics suggests the following statement on An “Environmentally Friendly
Use Period” (EFUP) setting out normal use:
EFUP is the time the product can be used in normal service life without leaking the hazardous materials.
We expect the normal use environment to be in an equipment room at controlled temperature range
(0ºC - 40ºC) with moderate humidity (< 90%, non-condensing) and clean air, not subject to vibration or
shock.
Further, a statement on any hazardous material content, for instance, for a product that
uses some tin/lead solders:
Where a product contains potentially hazardous materials, this is indicated on the product by the
appropriate symbol containing the EFUP. The hazardous material content is limited to lead (Pb) in some
solders. This is extremely stable in normal use and the EFUP is taken as 50 years, by comparison with the
EFUP given for Digital Exchange/Switching Platform in equipment in Appendix A of “General Rule of
Environment-Friendly Use Period of Electronic Information Products”. This is indicated by the product
marking:

HD-EO Rev. 2
20
50
It is assumed that while the product is in normal use, any batteries associated with real-time clocks or
battery-backed RAM will be replaced at the regular intervals.
The EFUP relates only to the environmental impact of the product in normal use, it does not imply
that the product will continue to be supported for 50 years.
Recycling information
Network Electronics provides assistance to customers and recyclers through our web
site http://www.network-electronics.com. Please contact Network Electronics’
Customer Support for assistance with recycling if this site does not show the
information you require.
Where it is not possible to return the product to Network Electronics or its agents for
recycling, the following general information may be of assistance:
Before attempting disassembly, ensure the product is completely disconnected from
power and signal connections.
All major parts are marked or labelled to show their material content.
Depending on the date of manufacture, this product may contain lead in solder.
Some circuit boards may contain battery-backed memory devices.
