The Cisco® CRS-3 Carrier Routing System offers industry-leading performance, advanced services intelligence, environmentally conscious design, and system longevity. The Cisco CRS-3 is powered by the Cisco QuantumFlow Array - a chipset architecture based on multidimensional engineering and Cisco IOS® XR Software, a unique self-healing, distributed operating system.

Packet-based data communications are being replaced by video and rich media traversing the IP Next-Generation Network (NGN) in multiple directions, straining the architectural foundations of both public and private networks serving businesses and consumers. As part of the medianet, a media-aware Cisco IP NGN, the Cisco CRS-3 delivers continuous, always-on operations and scales easily from numerous single-chassis form factors to a massive multi-chassis system. Its design provides an industry-leading efficiency consuming lowest power, cooling and rack-space resources for an intelligent service-rich bandwidth capacity. The CRS-3 builds on the CRS-1 being backward and forward compatible, protecting existing and future investments for decades to come.

The post-amplifier module is directly fed by the pre-amplifier module and outputs the high optical power level required to feed the Passive Optical Network (PON). There are two main types of post- amplifiers, double-wide and single-wide.

The double-wide post-amplifier module is normally used in a temperature controlled Headend or CO environment. The double-wide post-amplifier module is available in a variety of output port counts (8 to 24 ports). These modules are configured with high density LC/APC optical connectors.

The single-wide post-amplifier module is temperature hardened for use in applications having less temperature control than a headend or CO environment. The single-wide post-amplifier modules have 4 output ports at 17, 18.5, and 19.5 dBm per port, and are configured with SC/APC optical connectors.
