In order to find a cost effective way to increase date rate, multiple communications companies announced the release of a quad small form-factor pluggable (QSFP) optical module specification in its final form in December 4, 2006. The QSFP specification defines a highly integrated four-channel optical transceiver to provide increased port density and total system cost savings when replacing four standard SFP transceiver modules. Since then, the 40GBASE QSFP module has become a dominant 40G optical transceiver and offers customers a wide variety of high-density 40 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider transport...

With the economics-driven growth of global regional and local fiber communication network over the past few decades, the IEEE 802.3 ba 40Gb/s Ethernet standard was published in June, 2010. In order to meet the data transmission needs in the market, a high-performance and flexible implementation of the IEEE 802.32012 for 40Gbps Ethernet - 40GBase optical transceivers are developed and widely used. The 40GBase optical networking equipment transfers data at a rate of 40 gigabits per second over Ethernet.

40GBase optical transceivers, compliant to the IEEE standards mainly include CFP and QSFP (quad small form-factor pluggable). Today, let’s mainly discuss on how to choose the 40G QSFP transceiver. As the 40-Gigabit QSFP transceivers are...
