What is QSFP112?

QSFP112 represents the evolution of the QSFP transceiver form factor.  Its streamlined, four-electrical lane architecture delivers a remarkable reduction in power consumption compared to its predecessor, QSFP-DD. 


Why is QSFP112 important?

In the ever-expanding landscape of data center infrastructure, transceivers number in the thousands.  As the pursuit of unparalleled efficiency marches on, QSFP112 emerges as the transceiver technology that significantly reduces power consumption in 400G interconnections.


What are the advantages of QSFP112?

Lower cost

Fewer electrical connections mean a reduction in both internal electronics and manufacturing components. Fewer components result in a significant drop in cost per QSFP112 transceiver, as compared to its predecessor, the QSFP-DD.

Lower power consumption

QSFP112 transceivers consume typically 3.5 W less power than other 400G transceivers. This remarkable 29% reduction in power consumption establishes the QSFP112 as the frontrunner in the high-speed transceiver market.

Reduction in carbon footprint

Data centers represent 1%-2% of global power consumption. Considering there are many thousands of transceivers per data center, a drop of 30% in transceiver power requirements delivers an enormous improvement in environmental impact.
