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:
• Fixed gain mode (with programmable tilt)
• Standard gain range of 8 to 20 dB in the programmable gain tilt mode
• True variable gain
• 20 to 27 dB gain range in the uncontrolled gain tilt mode
• Built-in VOA to control gain tilt
• Fast transient suppression
• Nondistorting low-frequency transfer function
• Settable maximum output power
• Fixed output power mode (mode used during provisioning)
• ASE compensation in fixed gain mode
• Full monitoring and alarm handling with settable thresholds
• OSRI
• ALS
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.
4.6.1 OPT-BST-L Faceplate Ports
The OPT-BST-L amplifier has eight optical ports located on the faceplate:
• MON RX is the output monitor port (receive section).
• MON TX is the output monitor port.
• COM RX is the input signal port.
• LINE TX is the output signal port.
• LINE RX is the input signal port (receive section).
• COM TX is the output signal port (receive section).
• OSC RX is the OSC add input port.
• OSC TX is the OSC drop output port.
