Cisco is the worldwide leader in networking that transforms how people connect, communicate, and collaborate. Their technology is changing the nature of work and the way we live. Founded in 1984, Cisco pioneered the development of Internet Protocol (IP)-based networking technologies. This tradition continues with the development of routing, switching, and other technologies such as application networking services, home networking, security, storage area networking, TelePresence systems, unified communications, video systems, and wireless.
The Cisco Catalyst 2960X-STACK= Flexstack-Plus Network Stacking Module is designed for use with Cisco Catalyst 2960X-24 Network Switches. Cisco Catalyst 2960-X Series switches are fixed-configuration, stackable Gigabit Ethernet switches that provide enterprise-class access for campus and branch applications and offer a range of advanced Cisco IOS Software features.
The Cisco QSFP BiDi transceiver has two 20-Gbps channels, each transmitted and received simultaneously over two wavelengths on a single MMF strand. The result is an aggregated duplex 40-Gbps link over a MMF duplex LC-terminated fiber cable. The connection can reach 100 meters on OM3 MMF or 150 meters on OM4 MMF, which is the same as 40-Gbps SR4. Figure 3 shows the technology concept of the Cisco QSFP BiDi transceiver.
