Frequently Asked Questions

QSFP112 Transceivers and Cables

Why do we need QSFP112?

QSFP112 is the most convenient and cost-effective to upgrade intra-data center networks from 200G (QSFP56) to 400G (QSFP112), leveraging existed fiber routes while preserving the current network's physical and logical structure. So there's no need to redesign layouts when advancing to 800G. Moreover, QSFP technology more effectively tackles signal quality and thermal challenges at higher speeds

What are the differences between QSFP112 and QSFP28/56?

QSFP112 focuses on the next generation of connectors, cages, and modules in the QSFP series. It aims to extend bandwidth by scaling single-lane speeds to 112 Gb/s. Hardware changes are expected to enhance signal integrity performance and address EMI considerations.

Is QSFP112 backward compatible with QSFP56 and QSFP28 ports?

The QSFP112 port is backward compatible with legacy QSFP 40G (4x10G), 100G (4x25G), and 200G (4x56G-PAM4) modules and cables.

Can 400G QSFP112 modules be used on OSFP ports?

No. OSFP and QSFP112 are both fiber optic transceivers that support 400G data rates, but they have different sizes and interfaces.
