OM5 and Powered Fibre Cabling are both key offerings from CDI Group.

Powered Fibre Cabling:

Introduced by CommScope in January 2016, CDI Group now has a number of live installations where either of the following situations prevail:

1) an external long-distance requirement for both power and data. For example, at airports and external carparks, to power and serve perimeter security cameras.  These installations would normally have required both power and data cabling, however the Powered Fibre Cabling option means that one hybrid cable, served by a POE (Power Over Ethernet) box, can be installed with distances of up to 300m (x30 that of CAT 5).

2) an internal requirement for simultaneous power and data.  For example: datapoints in hot-desking situations, allowing employees to both power and connect their devices.  This has provided even greater flexibility with installations, and created more efficiency with charging and data usage.

Powered Fibre Cabling benefits:

-Reduces the need for landlord and utility negotiations – “who pays for the power to this system”? etc

-Eliminates local power sources – handy for external installations where no local power source is available, or the terrain makes it difficult

-Removes the need for  DC electrical calculations for voltage/power drop over varying distances

-Handles up to 32 devices simultaneously from one power supply

-Contains carrier grade electrical protection

-Is NEC Class II and SELV compliant

-Allows for placing devices exactly where they are needed to maximize coverage


Multimode – or OM5


Multimode fibre might have first been conceived of in the 1980’s but it has come a long way since then.  Initially deployed in long-haul networks (one project being a dazzling 45Mb/s multimode fibre backbone from Boston to Washington DC).  Some 30 years later, whilst the home internet connection is still around 45Mb/s,  multimode now typically operates at 100Gb/s and beyond and presents the lowest total system cost for high-speed systems in commercial buildings and data centres.

OM5 News

The OM5 designation has now been accepted by International Electrotechnical Commission standards, or ISO/IEC 11801.  Which is a good thing, because “Cabling containing WideBand Multimode Fibre” was never a snazzy enough name … ( in our humble opinion)

But less of the semantics – what has this new fibre standard got to offer?

-The new designation of market acceptance of a new and revolutionary cabling performance category

-Extends benefits of multimode cabling within connected and efficient buildings

-Cabling of choice for data centres worldwide

And the tech specifications:

OM5 supports legacy applications as well as, if not better than OM4, and is fully compatible with OM3 and OM4 cabling.

OM5 has been designed to support a minimum of 4 low-cost wavelengths across the 850-950 nm range. This means optimised support of emerging SWDM ( Shortwave Wavelength Division Multiplexing) applications that reduce parallel fibre count by at least a factor of four, allowing continuous use of only  two fibres (instead of 8 ) for transmitting 40 Gb/s and 100 Gb/s and reduced fibre counts for higher speeds.


CDI has been installing cabling networks worldwide since 1987.  We have seen and worked in most conditions and faced any number of challenges.
