Cisco (15454-OPT-PRE=) Repeater

Optical amplifiers are used in amplified nodes such as hub nodes, amplified OADM nodes, terminal nodes, and line amplifier nodes. The optical amplifier card architecture includes an optical plug-in module with a controller that manages optical power, laser current, and temperature control loops. The amplifier also manages communication with the TCC2, and operations, administration, maintenance, and provisioning (OAM & P) functions such as provisioning, controls, and alarms. The OPT-PRE is a C-band DWDM, two-stage erbium-doped fiber amplifier (EDFA) with mid-amplifier loss (MAL) for allocation to a dispersion compensation unit (DCU). To control the gain tilt, the OPT-PRE is equipped with a built-in VOA. The VOA can also be used to pad the DCU to a reference value. ??PRODUCT FEATURES:??Fixed gain mode with programmable tilt;?True variable gain;?Fast transient suppression;?Nondistorting low-frequency transfer function;?Settable maximum output power;?Fixed output power mode (mode used du...
