ZINWAVE 2700 DAS INSTALLATION
868
5.1
Cabling installation
869
5.1.1
General
870
The installation of optical fibre cabling shall be in accordance with the EN 50174 series of standards.
871
872
5.1.2
Cables
873
5.1.2.1
ZinWave TO cables
874
The ZinWave TO cables shall be selected from those of Table 3-9 in order to allow sufficient spare cable for subsequent
875
dressing in cabinets/frames/racks and for the inclusion, where appropriate, of service loops at specific locations.
876
877
The pre-terminated end of the TO cables shall be protected during their installation and the end caps shall not be
878
removed prior to, or during, the installation of the cables.
879
880
5.1.2.2
Coaxial cables
881
Coaxial cables are used to deliver/access the services supported by the ZinWave 2700 DAS:
882
•
at the ZinWave 2760 or 2776 Antenna Unit
883
•
at the ZinWave 2700 Hub
884
885
The interfaces on both the 2760 Antenna Unit and the ZinWave 2700 Hub are SMA-style. The interfaces on the 2776
886
Antenna Unit is N-style.
887
888
At the ZinWave 2760 Antenna Unit, it is expected that the service-specific antennae will be connected via small diameter
889
coaxial cables that are compatible to the SMA interface.
890
891
At the ZinWave 2776 Antenna Unit it is expected that that the service-specific antenna will be connected via a coaxial
892
cable that is compatible to the N interface.
893
894
In the vicinity of the ZinWave 2700 Hub Unit, the RF sources may be presented on larger coaxial cables that are not
895
physically compatible to the SMA interface of the Hub Unit. It is therefore required to install a separate interface panel, in
896
association with the ZinWave 2700 Hub Unit, that provides a fixed conversion from the larger coaxial cables to cables
897
that are physically compatible to the SMA interfaces on the ZinWave 2700 Hub Unit.
898
899
5.1.2.3
Balanced cables for the provision of remote power to the ZinWave 2760 or 2776 Antenna Units
900
The cables shall be in accordance with Category 5e of ANSI/TIA/EIA-568-B-2 or Category 5 of EN 50173-1 (equivalent
901
to Category 5 specified in ISO/IEC 11801:2002)
902
903
5.1.3
Fitting of the ZinWave TO Closure
904
The ZinWave TO Closure should be fixed in its desired location after the termination of the balanced cable (see 5.1.2.3
905
and 5.1.4.3) has been completed and the balanced cable glanded and dressed into position within the closure.
906
907
Once the ZinWave TO Closure has been fixed in position and the TO cable(s) installed:
908
•
blanking plate(s) covering optical fibre port(s) may be removed and the SMF adaptor(s) installed;
909
•
the TO cable(s) can be inserted into the SMF adaptor(s);
910
•
the external caps of the SMF adaptor(s) shall remain in place.
911
912
5.1.4
Cable termination
913
5.1.4.1
Multimode optical fibre cables
914
The termination of all multimode optical fibres to be used by the ZinWave 2700 DAS shall be via the fusion splicing of
915
ZinWave hi-conn pigtails as detailed in Table 3-8. The adaptors shall be SMF variants of the relevant connector style.
916
917
WARNING:
Only fusion splice techniques shall be used to joint the installed optical fibres to the ZinWave hi-conn pigtails.
918
Mechanical splices shall not be used
919
