Ethernet ports
There are four 100Base-Tx Ethernet electrical ports (two ports are uplink ports
used to connect with transmission network and the other two are local data ports
used to connect with local Ethernet), and one 100Base-Fx optical port used as either
uplink port or local data port. Ethernet electrical port supports three modes:
auto-negotiation, 10M full duplex/half-duplex and 100M full-duplex/half-duplex.
Ethernet optical port supports auto-negotiation or 100M full-duplex mode.
Ethernet built-in layer-2 switches function. Supporting Ethernet packet size up
to 9720byte, VLAN setting based on 802.1Q or QinQ, QoS setting based on port
、
8021.1P and TOS. There are four priority settings.
Ethernet electrical port adopts RJ45 socket. RJ45 Ethernet socket is defined in
Table 2.3-5. Ethernet optical port can use double-fiber SFP optical module and the
port labeled
（
is for optical signal output,
（
for input. Also Ethernet optical port
can use single-fiber optical module which has only one optical interface. Depending
on different transmission distance, Different SFP optical module could be selected.
