SFP Gigabit Modeoptical Module

 Dongguan Suwang Hardware Products Co., Ltd.s the demand for bandwidth grows, the need to the single lane speed in a QSFP is now coming to 112Gbps. QSFP112 is the module and cage/connector system based on current QSFP, targeting to support the 112Gb/s per lane speed in a 4x lane QSFP system and to enable the QSFP 400G interconnect ecosystem. This will greatly help the legacy QSFP users upgrade the link bandwidth to 400G per port with lower cost and shorter transition time.
The QSFP112 MSA will define the module and cage/connector form factor to support the 112G-PAM4 electrical and optical signaling, and the increased high power consumption from various types of optical modules. The QSFP112 connectors and cages will be backward compatible with legacy QSFP 40G(4x10G), 100G(4x25G) and 200G(4x56G-PAM4) modules, including optical transceivers and copper cables. The QSFP112 modules will also be able to be accepted by QSFP-DD connector and cage. The QSFP112 will be able to support both optical and copper interfaces, but those physical layer specifications will be done outside of the MSA specification as is usual for form factor MSA specifications.
