OPT-BST Card Description

Optical amplifiers have a linear power feature that enables them to be kept in the constant gain mode.

The OPT-BST gain range is 5 to 20 dB in constant gain mode and output power mode. In constant power

mode, automatic power control (APC) requirements change. The change occurs because span loss

degradation does not effect the system, and amplifiers cannot automatically modify the output power for

variations in the number of channels when a failure occurs.

Figure 1 shows the card faceplate, Figure 2 shows a block diagram of the card, and Figure 3 shows an

optical module functional diagram of the OPT-BST card.
