2.2.4.3 OPT-BST-L Card

The OPT-BST-L card is an L-band DWDM EDFA with OSC add/drop capability that can operate up to 64 optical transmission channels at 50-GHz channel spacing over the L band of the optical spectrum (wavelengths from 1570 nm to 1605 nm). To control gain tilt, the card is equipped with a built-in VOA managed by the card microprocessor. The OPT-BST-L provides the following features:

True variable gain

Fixed gain mode (with programmable tilt)

Fast transient suppression

Nondistorting low frequency transfer function

Settable maximum output power

Fixed output power mode (mode used during provisioning)

Constant drive current mode (test mode)

Amplified spontaneous emission (ASE) compensation in fixed gain mode
