QSFP+ modules in a single line card bandwidth per upgrade

Standards bodies initially offered several options for the 10-Gigabit transceiver. 10G transceivers series include QSFP+ Transceiver, XFP Transceiver, SFP+ Transceiver, 10G XENPAK Transceiver and X2 Transceiver. The one that ultimately evolved as most popular in commercial data center usage was the SFP+ transceiver. The Cisco 10GBASE SFP+ modules offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications. Avago Technologies has announced the launch of the exchange can improve data center efficiency and bandwidth of the fiber-optic module program. New pluggable parallel optical QSFP+ copper cables transceiver module product can solve the industry’s first 40G and 10G Ethernet applications problems, connection distance up to 400 meters proved, for the data center operation industry by providing access to existing 10G connection infrastructure upgrades to 40G high flexibility and substantial savings in cost expenditures. Avago’s QSFP+ eSR4 modules in a single line card bandwidth per upgrade to the integrated four 10G channels more than three times more than the power consumption is only a single channel SFP+ module less than half.

With server virtualization and EMI plugs cloud computing development, coupled with the trend of network integration, bringing a greater demand for faster and more efficient data center network, currently 10G switch 10G channel 48 line cards per piece mainly limited by the SFP + form factor. To meet the demand for higher bandwidth, customers can use Avago the QSFP+ eSR4 module developed up to 44 line cards per piece QSFP+ port top-of-rack (Top-of-Rack), blade and module switch, bringing with QSFP+ up to 176 a 10G channel products, significantly beyond the existing 48 SFP+ channel. The QSFP + module can be applied in high-density 10G and 40G aggregation Ethernet applications, providing higher flexibility to connect the different levels of exchange and shorten the delay and higher port density, and lower power consumption per channel .
