Cisco Catalyst 6900 Series 4-Port 40 Gigabit Ethernet Fiber Module with DFC4 - expansion module - 4 ports

The Cisco Catalyst 6900 series 4-Port 40 Gigabit Ethernet Fiber Module, fully compliant with the IEEE 802.3ba standard, complements this product portfolio. The module is designed to meet the increasing demand for aggregation of 10 Gigabit Ethernet on campus and data center, as well as for high-density 10 Gigabit Ethernet and 40 Gigabit Ethernet transport in the core. Each port can accept a 40 Gigabit Ethernet C Form-Factor Pluggable (CFP) optics module or be converted to four ports of 10 Gigabit Ethernet with a FourX adapter, enabling customers to deploy 10 Gigabit Ethernet to meet current needs and be ready to transition to 40 Gigabit Ethernet without any disruption.
