In this article, ETU-LINK will introduce the 100G QSFP28 and 25G SFP28 cost-effective port branch connection solutions. The following will analyze and compare from the two aspects of saving space and cost. First of all, let's talk about why the cost performance is high, we can judge by comparing the cost. We can assume a scenario with an 8-slot chassis, which is fully equipped with 36 QSFP28 ports...

With the increasing demand of data center for bandwidth, the network rate is developing towards a higher rate, and there is bound to be the need for network upgrading. There are two upgrade paths for the network from 10G to 100G, namely 10G-25G-100G and 10G-40G-100G. End users seem to prefer 25G. Why? ETU-LINK will tell you.   All this can be said from the rise of 25 Ethernet. Data center TOR...

Metropolitan area network is a computer communication network established within a city, referred to as MAN. It is a broadband local area network. Due to the local area network technology with active switching elements, the transmission delay in the network is small, and its transmission medium mainly uses optical cables, and the transmission rate is above 100Gbit/s. An important use of MAN is for...

At present, 5G has started the commercialization process, but the complex bearer scheme leads to the increase of the corresponding optical module types. For 5G forward transmission, in terms of speed, AAU has introduced the eCPRI protocol standard, and the forward 25G rate has become the standard of various equipment manufacturers. Because of this, the rate standard of the carrier network will be ...
