3GHD-OE-2-SFP Rev. C
1 Product overview
The Flashlink 3GHD-OE-2-SFP 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 2970Mbps. Unmatched signal accuracy, even in critical applications with pathological
signal patterns makes the 3GHD-OE-2-SFP the first choice for all optical transport demands.
The 3GHD-OE-2-SFP can transport all SD, HD and 3G signal formats in addition to DVB-ASI
and SMPTE310M. It performs optical refreshing and signal re-clocking, which is selectable
on application. The optical inputs are embedded in optional SFP module, which makes the
module configurable to application specific needs. The open system platform of Nevion
Flashlink system allows easy interoperability with third party fiber optical systems.
The 3GHD-OE-2-SFP unit has also three electrical outputs for each converter, which reduces
the need for additional DA’s.

Control System. The layout is shown in the drawing below with the DIP switches to the upper
left position.

3.2.1 Re-clocker mode
The re-clocker can be set to re-clock or bypass from DIP#9 and DIP#13 or from GYDA.
When re-clocker is set to re-clock mode jitter from signal is removed. Accepted bitrates is
270, 1483.5, 1485, 2967 and 2970Mbps.
When re-clocker is set to bypass the converter accepts all bitrates between 2 to 2970Mbps.
Note that in this mode the jitter is not removed and this can cause problems for equipment
following the converter.
3.2.1.1 Transparency
This converter only looks at the bitrates and not the content. This means that any signal with
correct bitrates is converted. The product is transparent to data in the ancillary space like
embedded audio.
3.2.2 Display optical input power
The LED’s can be used as an optical power meter. This is practical under installation of the
module. The power measurement is not accurate but can be used as an indication of optical
power strength. Remember to turn this function of after installation. When all LEDs are green
the optical input power is more than -6.5dBm. When all LEDs are off input power is below 25dBm.
The DOP (Display of Optical input Power) can only be turned on from the DIP. DOP is turned
on by DIP#6.

3.2.3 Automatic change over
Dual optical converter has an automatic change over module. This module has the possibility
to have an automatic change over on the input. This can be used in redundancy systems
where the user wants automatically switch to a backup port when the main input loses signal.
This function can be selected with DIP#10 and Dip#14. Each converter can be configured to
be main and backup input by DIP#5 or from GYDA.
3.2.3.1 Trigger condition
Loss of optical power trigs the automatic change over. When the main input lose optical
power the backup input is selected. When the backup input is active an alarm is displayed in
GYDA. When the main input optical power is restored the converter switches immediately
back to main input and alarm is restored.
Note that bit error or loss of lock on re-clocker does not trigger the automatic
change over.

5 Operation
5.1 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.
5.1.1 Multicon Gyda status interface
Figure 15 Dual converter status tab
The on-board temperature measurement is a feature used for monitoring
variations in temperature over time and can be accessed thru SNMP. The
absolute value of the temperature measurement has little value of its own as it
does not reflect the temperature inside the electronics nor the ambient frame
temperature.
