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). Figure 1 - HD-EO – HD-SDI Electrical to Optical Converter for 1310nm

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 1 D/B Not in use Not in use Always in broadcast mode 2 E/O Not in use Not in use Always E to O mode 3 RCL Reclocker ON Reclocker Bypass Reclocker mode 4 EQ Cable equaliser ON Cable equaliser Bypass Equaliser mode 5 ASI DVB-ASI Reclocker support SDI 177Mbps Reclocker support Select ASI or 177Mbps support 6 GBE Not in use Not in use 7 622 Not in use Not in use 8 OVR Override GYDA control Config. with DIP switch GYDA control Config. with GYDA Select configuration from 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.

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. This manual is also available from our web site: http://www.network-electronics.com/

The table below shows which signal formats are supported on the selected terminals. Terminal format support: Terminal Function Supported Format Mode DIGITAL INPUT Electrical Input HD-SDI, SDI, DVB-ASI, SMPTE310, Transparent* Input DIGITAL OUTPUT 1 Electrical Output – None inverted Reclocked DA output HD-SDI, SDI, DVB-ASI, SMPTE310, Transparent* Output DIGITAL OUTPUT 2 Electrical Output – Inverted Reclocked DA output HD-SDI, SDI, Transparent* Output OPTICAL Optical Output (Transmitter) HD-SDI, SDI, DVB-ASI, SMPTE310, Transparent* Output GPI ALARM Open Collector Alarms Wired alarms OC 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.

The LED’s are visible through the front panel as shown in figure 5 below. (Text not printed on the front panel). Figure 5 - Front panel indicator overview for HD-EO The HD-EO has 4 LED’s each showing a status corresponding to the GPI pinning. The position of the different LED’s is shown in figure 5.

Laser 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 power*: 5 mW. Operating wavelengths: > 1270 nm. *Max power is for safety analysis only and does not represent device performance.
