3GHD-EO-2-SFP Rev. B
1 Product overview
The Flashlink 3GHD-EO-2-SFP is a dual multi bit-rate electrical to optical 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-EO-2-SFP the first choice for all optical transport demands.
The 3GHD-EO-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-EO-2-SFP unit has also two electrical outputs for each converter, which reduces
the need for additional DA’s.

3.2.1 Cable EQ
Electrical input cable eq. can be turned on and off. If SDI signal is used on the input it is
advised to set the EQ to on. The input will then adjust for the loss of high frequency
component from SDI signal. This will increase the working cable length on the input. If none
SDI signal is used on the input, turning of EQ may help increase the cable length if required.
3.2.2 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.
3.2.2.1 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.
3.2.3 Automatic change over
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.
The main and backup input can be selected with DIP#5 or from GYDA.
3.2.3.1 Trigger condition and latching
Loss of electrical signal on input trigs the automatic change over. When the main input lose
electrical signal the backup input is selected. When the backup input is active an alarm is
displayed in GYDA. When the main input electrical signal is restored the converter switches
immediately back to main input and alarm is restored if latch is set to off. If latch is set to on
the fall back to main input will not happen before the reset is applied to the changeover from
the config pan in Multicon Gyda.
Note that bit error or loss of lock on re-clocker does not trigger the automatic
change over.

4 Operation
4.1 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.
4.1.1 Multicon Gyda status interface
Figure 11 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.

3GHD-EO-2-SFP Rev. B
5 Connections
The 3GHD-EO-2-SFP has a dedicated connector module; 3GHD-EO-2-C1. This module is
mounted at the rear of the sub-rack. The layout of the module is shown in the figure below.
Figure 12 Connector module for 3GHD-EO-L-2-SFP
Figure 13: Fiber layout
Out1 as shown in Figure 13 will always have the lowest wavelength when CWDM
and DWDM SFP’s is installed. So if the SFP installed is a 23033 SFP-3G-EO-2C1xxx/C1xxx with the wavelengths 1590/1610, Out1 will be 1590 and Out2 will
be 1610.
5.1 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.

5.3 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 activated. The GPI connector is
shown in figures below.
