3.6.3.2

Network Connection

Shielded four-pair (8-conductor) 100-ohm twisted-pair cable such as PIC Wire and

Cable Datamates E50824 or equivalent (Figure 3.6.3.2-1) is recommended for the

1000BASE-T Ethernet connection between the ABR and the Network Router and for the

Maintenance Ethernet port connection. Shields should be grounded to the connector

backshell at the ABR, and to the RJ-45 shield at the router end. If the network cable is

required to penetrate the pressure vessel, an appropriate bulkhead feedthrough which

preserves signal and shield integrity should be used. Reference Section 5.1.3 for wiring

information and 5.2.5 for connector shielding information.

RF Cabling

3.6.4.1

Coax Cable

Any Triple-shielded coaxial cable, which meets or exceeds burn requirements per

Federal Aviation Regulations 14 CFR Part 25.869(a) (4) Amendment 25-113, Appendix

F Part I(a)(3), and which is manufactured with materials that, when subjected to flames

or high temperatures, will not outgas deadly hydrogen chloride (such as is produced by

conventional PVC cables) is acceptable for the installation. The cable must also meet or

exceed RF performance characteristics for the length selected.

NOTE: Receive (RX) coaxial cables between the Aircraft radio and the HPB should be

equal in length within 12 inches.
