Appendix B: AF-5X and
airFiber Multiplexer
Note: This appendix applies to the airFiber AF-5X
radio when used with the airFiber NxN Multiplexer.
The following provides important information for using
the AF-5X radio with the airFiber NxN Multiplexer (models
AF-MPx4 or AF-MPx8). For a successful deployment,
ensure that all additional steps are taken and that all
information is taken into consideration.
• During initial configuration of each AF-5X radio, input
the additional cable loss associated with the multiplexer,
and enable the NxN Radio setting. For details, refer to
Step 6 of “airFiber Configuration” on page4.
• When performing antenna alignment, perform the
procedure in “Establishing a Link” on page9 on
one radio only. This will help ensure maximum success
in registrations.
• After the first radio has been aligned with the other side
of the link, ensure that the TX power balance is present.
• To maintain 8x performance, maximum TX power
should not exceed 19-20 dBm.
• If 8x performance cannot be achieved at these TX power
levels, it may be possible to improve performance by
increasing channel spacing.
airFiber X Compatibility
The airFiber NxN is designed for use with airFiber 5X
radios, (model AF-5X) and 5 GHz airFiber X or RocketDish
™
antennas.
Note: The airFiber X Antenna OMT Conversion Kit
(AF-5G-OMT-S45) is highly recommended when
using a RocketDish for proper fitting and improved
frequency isolation.
Installation Requirements
• (2) airFiber 5X radios for AF-MPx4
• (4) airFiber 5X radios for AF-MPx8
• airFiber X or RocketDish antenna
• Clear view of the sky for proper GPS operation
• Ground wires – min. 10 AWG (5 mm
2
) and max. length:
1m. Asa safety precaution, ground the airFiber radios to
grounded masts, poles, towers, or grounding bars.
WARNING: Failure to properly ground your
airFiber radio will void your warranty.
Note: For guidelines about grounding and
lightning protection, follow your local electrical
regulatorycodes.
• Outdoor, shielded Category 6 (or above) cabling and
shielded RJ-45 connectors are required for all wired
Ethernetconnections.

(AF-MPx8 Shown)
Chain 0 Connect the antenna RF +45° to this connector.
Chain 1 Connect the antenna RF -45° to this connector.
RF Cables Connect each RF Cable pair to the
corresponding RFconnection chain on each airFiber 5X
radio. For example, connect cable A0 to Chain 0, and
cable A1 to Chain 1.
