HD-OE-2/HD-OE-L-2/HD-OE-2-M Rev. 1
1 Product overview
The Flashlink HD-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
1485Mbps. This state of the art unit offers a high sensitivity PIN diode technology.
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 HD-OE-2 can transport all HD and 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 –20dBm operating in the 1200-1620nm wavelength range. The module is also
available as a long-haul version, called HD-OE-L-2 with typically -23dBm senitivity.
The open system platform of Network Electronics Flashlink system allows easy
interoperability with third party fibre optical systems.
A multi mode version for distances up to 300m, called HD-OE-2-M is also available.
The two independent electrical outputs are equipped with a distribution amplifier where 2
outputs reduces the need for additional DAs (for DVB-ASI only one can be used).

4 Connector module
The HD-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 HD-OE-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-OE-2, and the electrical output is
connected to the corresponding OUTx+ or OUTx- output BNC on the receiving HD-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+). 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 subrack frame FR-2RU-10-2.
This manual is also available from our web site:

4.2 Terminal format support
The different input and output ports on HD-OE-2 can support a number of formats. The table
below shows which signal formats are supported on the selected terminals.
Terminal format support:

HD-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 modus
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 LEDs 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.

5.2 Front panel – Status monitoring
The status of the module can be easily monitored visually by the LED’s at the front of the
module. The LEDs are visible through the front panel as shown in the figure below.

6 Laser safety precautions
These are 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 from 1310nm up to 1550nm. This means that the human
eye cannot see the beam, and the blink reflex cannot 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 fibre pigtails (ends).
Never look directly into the pigtail of the laser/fibre.
Never use microscopes, magnifying glasses or eye loupes to look into a fibre
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.

Appendix A Materials declaration and recycling information
A.1 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.
A.2 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:
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.
network-electronics.com | 15
HD-OE-2/HD-OE-L-2/HD-OE-2-M Rev. 1
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.
A.3 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.
