Switch Stacking vs Uplink: Which is Better for Connecting Switches?

Networks will eventually grow to the point that more switches should be integrated to increase port density and boost bandwidth. Then, should I buy switches with more ports or just connecting switch via stacking or uplink. Obviously, the latter makes more sense. Switch stacking vs uplink – is there any difference between them? In which case we should choose switch stacking over…

Things You Should Know about PSM4

In the current interconnection market, 100G QSFP28 transceiver has become a common trend of Ethernet due to its higher bandwidth, high data rate, lower cost and so on. To further keep pace with the market demands, many series of QSFP28 optical transceivers come into the data center, such as QSFP28 100GBASE-SR4/LR4, QSFP28 100GBASE-PSM4, QSFP28 100GBASE-CWDM4 and so on, in which…


Switch Stacking vs Trunking: What’s the Difference?

The performance of Ethernet switches is important in network design, for it will affect the whole network system working. Therefore, to achieve high performance, network managers may use different methods to improve the performance of network switches, which cause a hot topic: switch stacking vs trunking. In the article, the knowledge of switch stacking and trunking will be explored as…


All You Need to Know about 56G QSFP+ to QSFP+ DAC Twinax Cable

DAC is the short name for direct attach cable. Currently, there are many different types of DAC Twinax cables on the market such as SFP+ DAC Cable and QSFP DAC Cable. Terminated with transceiver-style connectors, they are designed to be used in the same ports as a typical SFP+ or QSFP transceiver, with no need for adaptors or converters, replacing…

What Is the Difference Between EPON and GPON?

With the prevalence of FTTH (Fiber To The Home)in the access networks, PON (Passive Optical Network) naturally plays a key role in it. To further keep pace with the demands, EPON (Ethernet Passive Optical Network )and GPON(Gigabit Passive Optical Network) emerges from PON and become popular versions of it. Maybe one is confused about the difference between EPON and GPON….
