10Gbps speed Ethernet connection may not be common seen in the office; however, administrator may has
Gigabit Ethernet in the control room of office already. Get a 10Gbps Ethernet connection from backbone and
distribute it to different Gigabit Ethernet segment for different building or organization is practical and more
cost-effective. Here is an example of possible plan.

This example is a possible network structure of a university.
A : Internet backbone from ISP.
B : The distance from the central office to the university might be long, so construct the connection via single-mode
optical fiber with 10BASE-LR mode, which can extend the distance beyond several tenth of kilometer.
C : XG2 is located at the computer center of university.
D : After the conversion of XG2, expensive equipment for transmitting/receiving network data via optical fiber is not
required afterward.
E : Full 10Gbps Ethernet Switch may beyond your budget or it is not available. Some 1Gbps Switch reserves a
swappable slot for the upgrade of future technology. Plug a 10Gbps module with one 10Gbps port to this kind of
Switch is enough for this application.
F : After the distribution of 1Gbps Ethernet Switch with attached 10Gbps module, several 1Gbps connections can
be distributed to different buildings inside the university by Cat. 6a network cable, which can be extended to 100
meters.
G, H, I : Different buildings or departments in one building. General switch with 1Gbps and 100Mbps ports can be
connected here for end-user.
