Introducing the Zyxel Device
1.1 Overview
The Zyxel Device is a GPON (Gigabit Passive Optical Network) router that offers dual-band WiFi
connectivity and comes with a built-in 4-port Gigabit Ethernet switch and two phone ports to make
Internet (VoIP) phone calls. The Zyxel Device also provides one 10 Gigabit Ethernet (10GbE) LAN port
that supports Multi-Gigabit. See
Section 1.1.1 on page 17 for more information about Multi-Gigabit.
1.1.1 Multi-Gigabit
A 10 Gigabit Ethernet port supports speeds of 10 Gbps if the connected device supports 10 Gbps and a
Cat 6a (up to 100 m) or Cat 6 cable (up to 50 m) is used.
Some network devices such as gaming computers, servers, network attached storage (NAS) devices, or
access points may have network cards that are capable of 2.5 Gbps or 5 Gbps connectivity.
If these devices are connected to a 1 Gbps or 10 Gbps Ethernet port, they can only transmit or receive
up to 1 Gbps as speeds of 10 Gbps cannot be attained. Moreover, if network devices with 10 Gbps
network cards are connected to a 10 Gbps Ethernet port, you must use Cat 6A or better Ethernet cables
to achieve 10 Gbps speeds. Most buildings, at the time of writing, use Cat 5e or Cat 6 Ethernet cables.
Multi-Gigabit Ethernet ports automatically allow connections up to the speed of the connected network
device (100 Mbps, 1 Gbps, 2.5 Gbps or 5 Gbps), and you just need to use a Cat 5e or Cat 6 Ethernet
cable.
See the following table for the cables required and distance limitation to attain the corresponding
speed.
1.2 Example Applications
This section shows a few examples of using the Zyxel Device in various network environments. Note that
the Zyxel Device in the figure is just an example Zyxel Device and not your actual Zyxel Device.
