The most prevalent Ethernet migration path until recently is accepted as 10G-40G-100G, however, the advancement in networking technology has ushered in a new alternative-25G Ethernet, indicating the lasted upgrade path could be 10G-25G-100G, or 10G-25G-50G-100G potentially. These migration solutions enable more efficient use of hardware and a more valid upgrade path to 100G. Optics like […]

Four Types of 100G QSFP28 Transceivers Overview
For 100G optical transceivers, there are a number of form factors including CFP/CFP2/CFP4, CXP and QSFP28. Among these different 100G form factors, it appears that the market has chosen QSFP28 as the primary form factor for 100G links. Hence, this post will focus on several types of 100G QSFP28 transceivers—100GBASE-SR4 QSFP28 transceiver, 100GBASE-PSM4 QSFP28 transceiver, […]
QSFP28 – A Better Way to 100G
The battle over 100G component market has been upgraded with the emerging of 100G QSFP28 module—an optical transceiver which can support 100G with the transmission mode of 4*25G. Before its appearance, the way to move to 100G is considered to be 10G→40G→100G. However, the new 100G road map with QSFP28 is 10G→25G→100G or 10G→25G→50G→100G. Currently […]
