Fiber Optic Transceivers
SFP28 vs. SFP+ vs. QSFP28
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 […]
Easiest Connectivity Solutions for 25G and 100G
Due to the increasing number of connected devices in use and their need for fast-based data processing, data centers are under pressure of transmitting data more quickly and efficiently. In order to keep pace with the rapid bandwidth increases, the applications standards organizations have been busy updating the recommended guidelines. Some intermediate speeds like 25 […]
100G Transceivers: CFP/CFP2/CFP4 and QSFP28
With bandwidth demands keep growing, network service providers are looking at 40G or 100G to accommodate the constant traffic surge. For 40G QSFP+ transceivers, they are interfaced with MTP/MPO or LC connectors, which has been introduced in a previous post: 40G Transceivers With MTP/MPO Interface vs. 40G Transceivers With LC Interface. So this article will […]
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, […]
40GBASE-SR4 vs. 40GBASE-SR BiDi: Which One Provides Higher Return of Investment (ROI)?
With data center consolidation, and server virtualization, the data center network is shifting to 10 Gbps at the access layer and 40 Gbps at the aggregation layer. To support 40G connectivity, data center architects are challenged by the need for a major upgrade of the cabling infrastructure. This article will introduce the 40GBASE-SR4 cabling solution […]
