Ethernet Traffic Interfaces
The front panel of the FibeAir IP-20F contains 4 x GbE combo interfaces (electrical or
optical) for Ethernet traffic. These interfaces are numbered as shown in Figure 2.
Figure 2: GbE Combo Interface Numbering
Important Note:
When using electrical ports GbE 1 through GbE 4 to connect
between the IP-20F IDU and an outdoor unit such as IP-20C or
IP-20S, in areas in which severe lightning conditions are likely to
occur, it is required to use lightning protection.
GbE 1/SFP 1 and GbE 2/SFP 2 can be configured as normal Ethernet traffic interfaces or
as cascading interfaces. When operating in cascading mode, these interfaces can
handle hybrid Ethernet and Native TDM traffic, enabling operators to create links
among multiple IP-20 units in a node for multi-directional applications based on hybrid
Ethernet and Native or pseudowire TDM services..
In addition, two pairs of electrical and optical interfaces towards the right of the front
panel can be used to provide either two Ethernet interfaces or one Ethernet interface
and one radio interface:
•
RFU3/SFP5 and RFU3/2.5GE5
–
A combo interface that can be used as either
an SFP or RJ-45 RFU interface or an SFP or RJ-45 Ethernet interface.
•
SFP6/2.5GE6 - A combo interface (SFP or RJ-45) for Ethernet.
