The OPT-BST is designed to support 64 channels at 50-GHz channel spacing, but currently is limited to
32 channels at 100 GHz. The OPT-BST is a C-band DWDM EDFA with OSC add-and-drop capability.
When an ONS 15454 has an OPT-BST installed, it is only necessary to have the OSCM to process the
OSC. You can install the OPT-BST in Slots 1 to 6 and 12 to 17. To control the gain tilt, the OPT-BST
is equipped with a built-in VOA.
The OPT-BST features include:
