PRODUCT BRIEF Intel Ethernet QSFP+ Optic QSFP+ 40GBASE-SR4 and 40GBASE-LR4 Optics for Intel Ethernet Network Adapters Key Features Overview Support for 40GBASE Ethernet Intel Ethernet QSFP+ Optics offer customers an efficient way to move to 40GbE for high bandwidth application requirements such as content Hot-swappable 40GbE I/O transceiver that plugs into a distribution, high-end virtualization using multiple CPUs, network QSFP+ port appliances, and Applications Delivery Controllers (ACD). When used with Supports the 4x10 GbE mode to the Intel Ethernet Network Adapter XL710, these optics support either connect to four 10GBASE-SR or 40GbE or 4x10GbE mode for four 10GBASE-SR or 10GBASE-LR 10GBASE-LR optical interfaces optical interfaces. Four channel, full duplex transceiver module To ensure maximum flexibility, Intel supports the ability to use either Single MPO receptacle (SR) Intel Ethernet QSFP+ Optics or direct attach twinaxial cables. This helps Single LC receptacle (LR) customers create the configuration that best meets the needs of their Maximum power dissipation data center environment, while ensuring compatibility between adapter < 1.5 W SR4 < 3.5 W LR4 and accessories. RoHS-6 compliant (lead-free) Commercial temperature range 0-70 C Maximum link length 10 km on Single Mode Fiber (SMF) Maximum link length 100 m on Multimode Fiber (MMF) 1.06 Gb/s to 10.5 Gb/s per channel multi-rate capability Compatible with Intel Ethernet Network Adapters GENERAL SPECIFICATIONS Module Form Factor QSFP+ Network Standards Physical Layer Interface 40GBASE-SR4 and 40GBASE-LR4 (4 x 10 GbE and 1 x 40 GbE) QSFP+ Module Specifications INF-8438i Specification for QSFP (Quad Small Form factor Pluggable) Transceiver SFF-8436 Specification for QSFP+ Copper and Optical Transceiver IEEE 802.3ba PMD Type 40GBASE-SR4 or 40GBASE-LR4 Number of Lanes 4 Tx and 4 Rx Airflow and Temperature Guidelines Refer to adapter product brief for specific airflow and temperature requirements1 NOTE: When two Intel Ethernet Network Adapter X520 and XL710 Series QSFP+ devices are connected back to back, they should be configured with the same Speed/Duplex setting. Results may vary if speed settings are mixed.
