3GHD-OE / 3GHD-OE-2 Rev. F

1 Product overview

The Flashlink 3GHD-OE and 3GHD-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 2970Mbps. Unmatched signal accuracy, even in critical applications with pathological signal patterns makes the 3GHD-OE and 3GHD-OE-2 the first choice for all optical transport demands.

The 3GHD-OE- and 3GHD-OE-2 can transport all HD and SD signal formats in addition to DVB-ASI and SMPTE 310M. It performs optical refreshing and signal re-clocking, 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 with typically -30dBm sensitivity. The open system platform of Nevion Flashlink system allows easy interoperability with third party fibre optical systems.

The 3GHD-OE and 3GHD-OE-2 unit has also three electrical outputs for each converter, which reduces the need for additional DA’s

3.3 Reclocker mode

The reclocker can be set to reclock or bypass from DIP#1 and DIP#3 or from GYDA. When reclocker is set to reclock mode jitter from the signal is removed. Accepted bitrates is

270, 1483.5, 1485, 2967 and 2970Mbps. When reclocker is set to bypass the converter accept all bitrates between 19.4 to 2970Mbps.

Note that in this mode the jitter is not removed and this can cause problems for equipment following the converter.

3.3.1 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.

3.4 Display optical input power (long-haul version only)

On the long haul version the LEDs 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 signal 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 LED are off input power is below -25dBm.

The DOP can only be turned on from the DIP. DOP is turned on by DIP#7 and DIP#6 select input port.

3.5 Automatic change over

Dual optical converter has an automatic changeover 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 turned with DIP#5. From GYDA this function can be turned on for each converter. Each converter can be configured to what is main and backup input by DIP#2 and DIP#4 or from GYDA.

3.5.1 Trigger condition

Loss of optical power trigs the automatic change over. When the main input loss 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 the alarm is restored.

Note that bit error or loss of lock on reclocker does not trigger the ACO.

6 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.

6.1 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 figures below.
