4.5.1    OPT-BST-E Faceplate Ports
 • Fixed gain mode (with programmable tilt)
 • True variable gain
 • Gain range of 8 to 23 dBm with the tilt managed at 0 dBm in constant gain mode and output power 
mode
 • Enhanced gain range of 23 to 26 dBm with unmanaged tilt
 • Built-in VOA to control the 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.
4.5.1 OPT-BST-E Faceplate Ports
The OPT-BST-E amplifier card 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.
