Installation of new backbone cabling
602
The installation of additional backbone cabling, integrated within the generic/structured cabling but intended for the
603
distribution of the ZinWave 2700 DAS has certain advantages by:
604
•
overcoming the reluctance on behalf of customers and/or installers to interfere with existing cable infrastructures;
605
•
maintaining the existing backbone capacity;
606
•
enabling lower channel insertion loss (see 4.3.3) and more secure distribution of the services provided over the
607
ZinWave 2700 DAS by using ZinWave Splice Panels (as shown in Figure 4-6 and Figure 4-8) in as many locations as
608
possible.
609
610
The installation of additional generic/structured backbone cabling provides considerable freedom in the selection of the
611
type of optical fibre to be used. The full range of all-silica optical fibres specified in the generic/structured cabling
612
standards including the ANSI/TIA/EIA-568 series standards, the EN 50173 series standards and ISO/IEC 11801 may be
613
considered.
614
615
The specifications of the cabled optical fibres in these standards are shown in Table 4-3. The sahded areas show
616
parameters that are not relevant for the ZinWave 2700 DAS but do influence selection for other applications.
617
618
As the ZinWave 2700 DAS is “fibre-agnostic”, any selection of media may be made on a number of criteria including
619
requirement to match existing cabling media, cabling installation cost, future requirements etc.
620
621
The selection of the optical fibre media to be used and how they are to be connected should also take into account the
622
considerations of channel length and channel insertion loss outlined in clause 4.3.3.
623
624
However, the final selection made has to be applied to all the cabling in the ZinWave 2700 DAS infrastructure.

Media selection
628
The number of TOs to be served by each ZinWave Local Splice Panel defines the number of optical fibres required to
629
feed that Local Distribution Panel from the ZinWave Building Termination or Splice Panel.
630
631
The installation of a stand-alone ZinWave DAS infrastructure provides considerable freedom in the selection of the type
632
of optical fibre to be used. The full range of all-silica optical fibres specified in the generic/structured cabling standards
633
including the ANSI/TIA/EIA-568 series standards, EN 50173-1 and ISO/IEC 11801 may be considered.
634
635
The specifications of the cabled optical fibres in these standards are shown in Table 4-3.
