Why 25G Ethernet Switches Are Still Necessary?

It has been about five years since the arrival of 25G Ethernet in 2014. For those years, the 25G Ethernet market has been filled with ups and downs. Facing with the broad adoption for 100G Ethernet and the upcoming new connection speeds of 200G/400G, the use of 25G devices, like the 25G switches, has been in doubt. A Review of…

Understanding 100G QSFP28 and CFP

Today, as 100G Ethernet widely deployed and becoming an important part of the data center, network device developers are increasingly motivated to produce 100G optical transceiver. Moreover, the produced 100G optical transceiver must consume less space, achieve a lower price, and have better performance, such as QSFP28 modules and CFP modules. They are also the themes we are going to…

Do You Know These about QSFP28 PSM4 Optics?

Although there have been 200G/400G optical transceiver products appearing in the optical communication market, and it does not mean that the era of 100G optical transceiver module has come to end. Actually, there still are various 100G QSFP28 optical module in great favour, such as 100G QSFP28 PSM4 and 100G QSFP28 CWDM4 optical transceiver, which meet users’ requirements for transmission…

Can QSFP+ Optics Be Plugged on the Port of QSFP28?

100G Ethernet is developed at the fast pace. With the prevalence of 100G network, various issues happen in the process of network establishment. For example, 100G QSFP28 optics commonly used in daily life can be available for 10kms transmission distance in 100G applications via WDM tech. However, there is an non-negligible fact that the price of WDM device is high…

Introduction to 10GbE/25GbE/40GbE/100GbE Fiber Optic Cabling

Technology is changing rapidly. Just when you got used to Gigabit Ethernet speeds being a fast & reliable system, someone unveiled 10GbE, 25GbE, 40GbE or even 100GbE systems a few years later. The newer and higher performing iterations are indeed the great breakthrough for telecommunication industry, but also pose difficulty in choosing network migration path—10G to 40G to 100G, or…

CFP 100GBASE-SR10 VS. 100G QSFP28 100GBASE-SR4

With the price of 100G optics cutting down, 2017 witnesses the great expansion of `100G hardware market. QSFP28 and CFP 100G optical transceivers are becoming popular among customers. Not only Cisco, HPE, Brocade, and Huawei, but the third party vendors like FS.COM offer 100G devices including the 100G switches, MTP/MPO cables, QSFP28, CFP/CFP2/CFP4 and so on. In this blog, I…

QSFP28 Transceiver With MTP or LC Duplex Cables

Nowadays, QSFP28 transceiver is the mainstream of 100G optics market. So as to meet different 100G deployment needs, QSFP28 modules usually come in several standards such as QSFP28 PSM4, QSFP28 CWDM4, IR4, SR4 and LR4, etc . Compared with CXP and CFP 100G optical transceivers, QSFP28 optics are the smallest form factors that provide a high-density and high-speed solution for…

Introduction to 100G Optics – CFP and QSFP28 Transceivers

2015 witnessed the prosperity of the telecom market. Many research company predicts that the market of 2016 for telecommunication field will continue to thrive. With such a bright future, fiber optics market attracts a wide attention and many vendors want a piece of the pie. At present, 40G is ubiquitous in the data center and 100G is accelerating. As for…
