The 75-ohm and 120-ohm clock cables are available.
The OptiX OSN 9560 supports input and output of 75-ohm and 120-ohm clock signals. However, 75/120-ohm clock transit
cables are required if the external ports that output clock source signals use 75-ohm connectors because STI boards on the
OptiX OSN 9560 provide only 120-ohm RJ45 connectors.
The OptiX OSN 9560 uses 120-ohm clock cables by default. If an OptiX OSN 9560 connects to an OptiX OSN 3500, use 120-
ohm clock cables to connect them. Clock cables between subracks can be made using network cables on site.
The 120-ohm clock cables must be shielded wires without cable sheaths.
