The Cisco ONS 15600 Series Multiservice Switching Platform (MSSP) offers up to 40 Gbps of transport bandwidth with Any Service Any Port (ASAP) interface cards, supporting 1 to 16 ports, providing users the capacity to aggregate and transport mission-critical regional and metropolitan-area (metro) traffic. ASAP brings outstanding performance using modular design, allowing single- and multiple-rate optics from OC-3 to OC-48, including Gigabit Ethernet Small Form-Factor Pluggable (SFP) optics (Figure 1) and DWDM. With Release 7.2, ASAP improves its tremendous flexibility with the addition of 10G pluggable optics.
