Описание
WS-X6904-40G-2T provides 4-port 40 Gigabit Ethernet Fiber connectivity, in which 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. The module is primary designed for campus, data center and service provider, as well as for high-density 10 Gigabit Ethernet and 40 Gigabit Ethernet transport in the core. WS-X6904-40G-2T is only compatible with Supervisor Engine 2T and supports two types of CFP optics: CFP-40G-LR4 and CFP-40G-SR4 to provide the distance up to 10-km over single-mode fiber and 100m over OM3 multimode fiber, respectively, it also supports Virtual Switch Link (VSL) on all ports.
