The flashlink SDI to Optical converter for DWDM is a multi bit rate converter module for use together
with the SDI-EO-C1 connector module. The unit can handle bit rates from 143Mbps up to 540Mbps. An
on-board cable equaliser provides up to 35dB gain at 200 MHz. This will typically result in equalisation of
more than 300 m of high quality coax cable at 270Mbps. The optical output is made with a DFB laser for
wavelengths according to ITU-T rec. G.692. The products are not sold separately, but as parts of a
flashlink®DWDM-system.
The product is available in 16 versions:

3. Connector module
The SDI-EO-D15xx.xx has the same connector module as the SDI-EO: SDI-EO-C1.
This module is mounted at the rear of the sub-rack.
The module is shown in figure 2.
Figure 2. Overview of the SDI-EO-C1 connector module
3.1 Applying signals to the connector module
The connector module is the same for the SDI-EO-D and the SDI-OE cards.
Apply the SDI signal to the BNC digital input connection. For monitoring purposes there are two
digital outputs as well. These signals have a loop-through function where the SDI signal applied at the
digital input is equalised and passed through a distribution amplifier to the two digital outputs. The signal
is the same at both outputs.
The optical connection is an SC/UPC connector with a return loss better than 40dB typ.
According to the specification SMPTE 259M, the return loss shall be better than 26 dB.

4. Module status
The status of the module can be monitored in three ways.
1. GYDA-SC controller.
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-SC controller
is a separate module giving detailed information of the status of the card. The functions of the GPI and the
LED's are described in sections 4.1 and 4.2. The GYDA-SC controller is described in a separate user
manual.
4.1 GPI – 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 2.
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V
SDI-EO-C1 GPI pinning:

4.2 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
LED's are visible through the front panel as shown in figure 4.
(Text not printed on the front panel).
Figure 4 Diode overview of SDI-EO-D
The SDI-EO-D has 3 LED's each showing a status corresponding to the GPI pinning. The position of the
different LED's is shown in figure 4.

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 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:
The FR-2RU-10-2 is classified as Class 1 laser product according to EN 60 825-1:94/A11:96, and
CFR Ch1(1997) Part 1040.10.
If the front panel is removed, the FR-2RU-10-2 is classified as Class 1 laser product according to
EN 60 825-1:94/A11:96, and classIIIb according to CFR Ch1(1997) Part 1040.10.
Maximum output power: 5 mW.
Operating wavelengths: 1310 nm or 1550 nm.
< 5mW
>1270nm
