The Brocade 10 Gb SFP+ SR Optical Transceiver is a Fiber SR multimode optical module for optical fiber connection support for the 42C1820 adapter option. This option is required for operating the 42C1820 adapter option with SFP+ Fiber SR multimode connection. The SFP+ Active Copper cables comes from the CEE switch supplier supporting attachment to this product. This adapter supports 10 Gbps per port maximum bidirectional throughput for high-bandwidth storage (SAN) & networking (LAN) traffic, with full hardware offload for Fibre Channel (FC) over Ethernet protocol processing. Convergence of SAN & LAN traffic on a single adapter & wire helps lower the total cost of ownership (TCO) by reducing the hardware, power, cooling, management, & maintenance costs. It offers investment protection by providing seamless compatibility with existing FC storage, Ethernet networks, driver software, & management applications. The PCI Express low profile form factor adapter can be used in either a standard PCI-E slot or a low profile PCI-E slot. This adapter is supported for all IBM System x modular rack servers, including the latest PCI Express 2.0 Generation 2 servers.
