demands.
Just take the application of wireless(Wi-Fi) access as the example, the technology of IEEE802.11ac is matured and very
popular for huge amount of multimedia data access in these years. Existing 1Gb backbone Ethernet network can not
fulfill the demands but become the bottleneck since the data rate of wireless technology already exceed 1Gbps. Then
how to upgrade and increase the bandwidth of existing network cable become an important task.
As you know, new wired technology for higher transmission data rate may need new physical cable with better quality
and higher dta bandwidth. But the problem is the Cat5e Ethernet cable is so popular and already deployed all over the
world in past tens of years. It will be very costly and difficult to replace the cable for new technology. The 10GBase-T
technology was already proven which is not possible to operate on existing Cat5e cable but need Cat6a or Cat7 cable.
Even though, it is still suitable for network distribution/data concentrator application.
For field side application, we need to find out a solution to increase the data rate on existing Cat5e Ethernet cable to
save cost and time. Therefore, the new standard of 2.5GBase-T was defined and developed for faster Ethernet data
transmission up to 100 meters like traditional 1Gb Ethernet network did. In addition, the PoE(Power over Ethernet)
technology is also possible to be implemented to deliver power and data within the same Ethernet cable.
ORing launched a new series of 2.5G/10G Industrial (PoE) Ethernet switch products for these applications. They are
the first 2.5G/10G Industrial grade Ethernet switch products with copper interface and PoE functions for industrial
applications with requirement of very high speed data transmission.
