20F Hardware Overview
FibeAir IP-20F is a compact unit that fits in a single rack unit, with a passive cooling
system that eliminates the need for fans. An IP-20F system consists of an IP-20F indoor
unit (IDU) and up to three radio frequency units (RFUs). The IDU is connected to each
RFU by a standard Cat-5e or preferably Cat-6/6e cable, with RF-45 connectors on the
RFU and electrical or optical fiber via SFP on the IDU. This cable transmits traffic and
management data between the IDU and the RFU. For RFU-S and RFU-D connected to
an electrical RFU interface on the IDU, this cable also provides DC -48V power to the
RFU. For RFU-S or RFU-D using an optical fiber connection, and for RFU-D-HP using an
electrical or optical fiber connection, an external DC power cable is required.
An IP-20F IDU contains:
•
Three 1 GbE combo interfaces
•
Two dual mode GbE or cascading combo interfaces
•
Two combo (RJ-45 or SFP) radio interfaces
•
An additional interface that can be configured as a combo (RJ-45 or SFP) radio
interface or a 1 GbE interface
For TDM traffic, an IP-20F IDU includes a 16 x E1/DS1 interface and two STM-1/OC-3
interfaces that require the addition of an optional rear-mounted STM-1/OC-3 module.
The STM-1/OC-3 interfaces can be used in a 1+1 STM-1/OC-3 protection configuration.
The IDU also includes two FE management interfaces, a DB9 dry contact external
alarms interface, and an RJ-45 terminal console interface for connection to a local craft
terminal. Optionally, one of the FE management interfaces can be used as an RJ-45
synchronization interface.
IP-20F receives an external supply of -48V, with a dual-feed option for power
redundancy.
