Opt-Bst-L Faceplate Ports - Cisco ONS 15454 DWDM Reference Manual

4.6.1 OPT-BST-L Faceplate Ports

Software R8.5 and earlieris limited to 32 channels at 100-GHz spacing.When an ONS 15454 has an
OPT-BST-L installed, an OSCM card is needed to process the OSC. You can install the OPT-BST-L in
Slots 1 to 6 and 12 to 17. The card's features include:
•
•
•

Note The optical splitters each have a ratio of 1:99. The result is that MON TX and MON RX port power is
about 20 dB lower than COM TX and COM RX port power.
