Product Description:
JetNet 3018G, the 16+2G Industrial Gigabit Ethernet Switch, provides high port density for large-scale Ethernet network applications, while ensuring lower system costs by less unit installation.
With the non-blocking switching performance, JetNet 3018G provides 12.8G on-chip backplane which ensures faster local transmission latency and efficient upstream transmission without data loss and blocking.
For large scale surveillance networks or for applications, which require large size traffic transmission, JetNet 3018G supports up to 9K Jumbo frame allowing to bypass larger file packets with fewer segments to the uplink networks.
With dual on board gigabit SFP uplink ports, the switch can flexibly develop high-density copper or fiber network connections with other high-end switches.
Just like the JetNet models, JetNet 3018G also supports 2 Digital Outputs to indicate fault conditions when a gigabit port link failure happens as a result increasing the system reliability.
JetNet 3018G is designed as a rugged surface in aluminum material housing with efficient heat dispersion capability and -25~70oC wide operating temperature to provide high-performance and reliable data transmission under severe industrial conditions. UL Listed 508

High Bandwidth and Performance

The JetNet3018G equipped with 16 100M Fast Ethernet plus 2 Gigabit Ethernet ports, totally requests at least 7.2G backplane for wire-speed and bi-directional transmission. To meet the requests, there are 2 types of system architecture - nonblocking and blocking.
In non-blocking architecture, the switch fabric should provide higher backplane than are the front ports’ requests. No matter it’s a one to one or fully mesh network, the throughput is always 100% without any loss.
The blocking architecture is usually implemented in non single chipset solution. Limited backplane may cause traffic jam when there is a heavy loading transmission among the ports.

The JetNet 3018G embedded 12.8G backplane is much higher than the system requires. All the traffic can be switching without blocking and loss. Up to 9K Jumbo frame allows transmitting larger files with less segments. The high bandwidth and performance solution guarantees the high capabilities of the product.

Up to 9KBytes Jumbo Frame Bypass

What is Jumbo Frame?

The typical Ethernet frame ranges from 64 to 1518 bytes. This is sufficient for general usage. However, when users need to transmit large files, the files may be divided into many small size packets. While the transmitting speed becomes slow, 9KBytes Jumbo frame can solve the issue.

Examples:
Transmitting large files, like the size of the LCD’s bitmap type circuit may reach up to 800MB. Network servers usually progress backups for lots of large files.

Jumbo Frame Packet Bypass

To run Jumbo Frame within the industrial environment, all the switches in the network must support Jumbo Frame feature. Once there is any Jumbo Frame unaware switch within the network, the Jumbo Frame will be dropped.
Korenix provides complete Jumbo Frame supported switches for allowing users to easily build a Jumbo Frame network. The JetNet 3018G acts as an entry level Jumbo frame switch to bypass up to 9K Jumbo Frame packet from the PC to the uplink network of higher level backbone switches.
