In June 2010, IEEE published the IEEE 802.3ba standard for 40 Gigabit and 100 Gigabit Ethernet. The market for 100G Ethernet is driven by high bandwidth switching and routing for core network aggregation of 10G and 40G Ethernet links. 40G and 100G Ethernet networks are more and more installed to meet the increasing requirement for higher speed and more bandwidth.

The CFP transceiver is defined as hot-pluggable optical transceiver form factors to enable 40 Gbit/s and 100 Gbit/s applications, which is specified by a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (centum). CFP transceiver was designed after SFP...

QSFP+ transceiver is a hot-swappable, parallel fiber-optical module with four independent optical transmit and receive channels. These channels can terminate in another 40-Gigabit QSFP transceiver, or the channels can be broken out to four separate 10-Gigabit SFP+ transceivers. For instance, QSFP-40G-SR provides four channels of data in one pluggable interface and each channel is capable of transferring data at 10 Gbps and supports a total of 40 Gbps. It uses 38 position connector and Electro Magnetic Interference (EMI) plugs are offered for empty ports to interface networking hardware to a fiber optic cable. The QSFP product family includes cages in single and ganged configurations with various heat sink and lightpipe...

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...
