The LR-LINK LREC9702EF-2SFP Dual-Port Server Adapter is PCIe 1GbE network ethernet adapters. Built with the Intel 82576 Gigabit Ethernet Controller, these new adapters showcase the next evolution in GbE networking features for the enterprise network and data center. These features include support for multi-core processors and optimization for server virtualization.
These dual-port adapter provide high-performing, dual-port Gigabit connectivity in a multi-core platform as well as in a virtualized environment. In a multi-core platform, the adapters support different technologies such as multiple queues, receive-side scaling, MSI-X, and Low Latency Interrupts, that help in accelerating the data across the platform, thereby improving application response times.
The I/O technologies on a multi-core platform make use of the multiple queues and multiple interrupt vectors available on the network controller. These queues and interrupt vectors help in load balancing the data and interrupts amongst themselves in order to lower the load on the processors and improve overall system performance. For example, depending upon the latency sensitivity of the data, the low level latency interrupts feature can bypass the time interval for specific TCP ports or for flagged packets to give certain types of data streams the least amount of latency to the application.

The LRGP8512-X5ATL transceiver is a high performance,cost effective module that supports data-rate up to 1250Mbps.
The transmitter section and the receiver section work independently in the transceiver.The receiver section contains an InGaAs PIN photo diode,a transimpedance amplifier and a post amplifier (with working data rate up to 1250Mbps),functionally transmit received optical power to steady electrical data.
This transceiver meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC-Duplex optical interface connector.An enhanced Digital Diagnostic Monitoring Interface compliant with SFF-8472 has been incorporated into the transceiver. It allows real time access to the transceiver operating parameters such as transceiver temperature, laser bias current,transmitted optical power, received optical power and transceiver supply voltage by reading a built-in memory with I2C interface.
