Due to the continuous growth of data center and cloud computing resource demand, the development of large-scale public cloud data center is driven. With the increasing of global data traffic, the data center is developing from 100g to higher speed, wider bandwidth and lower delay. 400G Ethernet becomes the inevitable trend of data center. TodayETU-Link will introduce 400G optical module in detail....
Since 2019, 400G has become a hot topic in the optical communications industry. Several leading optical module manufacturers in the world have launched their own 400G optical modules and most of them have adopted QSFP-DD packages. As early as March 21, 2016, the QSFP-DD MSA team began to plan to develop the QSFP-DD high-speed interface, and experienced the resolution of a series of issues suc...
Recently, 400G Ethernet has become a hot topic in the communication industry. It is both an outlet and a challenge. Network equipment manufacturers have launched 400G switches, and optical communication products have also launched 400G optical modules. In this article, ETU-LINK is about the impact of the emergence of 400G switches and 400G optical modules on data centers. First of all,...
At present, most 100G optical modules in the market are transmitted using 4 -channels 25Gb/s parallel or WDM,such as 100G SR4, 100G PSM4, 100G LR4, 100G CWDM4 optical modules, etc. In order to reduce costs and improve transmission efficiency, the industry has proposed the 100G single-lambda specification, which refers to the use of PAM4 optical signaling and coding for single-lambda 100G tran...
QSFP-DD, as the preferred packaging for 400G optical modules, can effectively expand the cloud capacity of data centers and meet the growing bandwidth requirements of ultra large data centers. In the previous blog, we introduced the 400G QSFP-DD FR4 optical module. Today ETU-LINK will introduce you the commonly used long-distance transmission solution for large-scale data centers -400G QSFP-DD LR8...
With the development and needs of mobile data, Internet, and big data, 400G OSFP is becoming more and more popular in the market. Speaking of 400G packaging form, most people blurt out QSFP-DD, and what we introduce to you today is another 400G packaging - OSFP. Let’s follow Xiao Yi to find out more! I.Concept analysis of OSFP optical module OSFP (0ctal Small Form-factor Pluggable) is ...
