3.4.1 Reclocker mode
The reclocker can be set to reclock or bypass from DIP#9 and DIP#13 or from GYDA.
When reclocker is set to reclock mode jitter from signal is removed. Accepted bitrates is 270,
1483.5, 1485, 2967 and 2970Mbps.
When reclocker 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.
3.4.1.1 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.
3.4.2 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 can only be turned on from the DIP. DOP is turned on by DIP#6.
