CASE STUDY
cable consists of 4 pairs individually wrapped in an overall
covering of high-quality aluminium/polyester foil tape,
providing an individual screen for each pair. These subunits
are then cabled together with the pairs set to different lay
lengths to ensure optimum performance.
An overall braid screen is applied to provide further
immunity to outside noise and to mitigate any risk of alien
crosstalk, which is especially important in an environment
where there will be frequent access to the network from
multiple devices, such as will be the case at TMA Toulouse.
What’s more, the Category 6A cabling was of Euroclass
Dca, s2, d2, a2 standard, as identified on the cable’s outer
sheath and box packaging, as well as in Excel’s Declaration
of Performance certificate. The cabling is fully compliant with
the European Construction Products Regulation (CPR), with
superior levels of smoke emission, flaming droplets and acid
gas production.
"The new system supports seve ral applications
including 10GBASE-T, adding to the future
proofing nature of the installation.
This product also lends itself to any high
definition bandwidth-hungry video footage
requirement, making it perfect for this project"
Over 4,000 Excel Category 6A Toolless Butterfly-Style
Keystone Jacks were loaded into 122 Excel Patch Panel
Frames. The keystone jacks open at the rear in a butterfly
manner and can be easily fastened quickly without the need
for tools once the cable has been terminated, making them
an ideal choice for this time-sensitive project.
The patch panel frames were fitted into Excel’s Environ
CR Racks, a versatile range of 800mm wide racks with
features suitable for a wide range of applications within
the data, security, audiovisual and telecommunications
markets. The CR Series offers 600Kg load rating, and
exceptional mounting space allowing the installation to
house the structured cabling and accompanying switches,
servers or networking equipment. The racks were fitted
with 145 Excel Cable Management Bars to help support
the cable and keep the infrastructure neat and secure. The
racks were also accompanied by Excel Power Distribution
Units, with French plug sockets to help control input power.
Horizontally mounted into the Environ cabinets for a higher
density solution, the PDU units supported the appropriate
management and distribution of power across the entire
installation.
Excel Enbeam Fibre Optic OS2 cabling was chosen as the
backbone cabling to support the installation. Excel’s OS2
cabling solution has been designed specifically for internal
and external applications, which is ideal for this space that’s
home to a range of open landscape and different buildings.
Compact, lightweight and extremely flexible and simple to
install, these cables were a great fit for the project. The cables
are constructed around a gel-filled (non-dripping and silicon
free) tube containing up to 24-colour coded 250μm primary
coated fibres. This tube is covered with water blocking E-Glass
fibre elements as strength members.
As per the copper cabling, the fibre cabling is compliant
to Euroclass Dca, s2, d2, a2. Fibre also provides an extremely
reliable backbone for data transmission back to the core, while
also being immune to lots of interference, caused by other
services within a building, there are no issues with the data
transfer. This was especially important for this project, where
there are various operations, businesses and start-ups in
action at the same time on the same campus. A solution that
supported the reduction of interference and the improved
transference of data was vital. The capabilities of the fibre
allowed the network to be designed to work with the vast
size of the facility and installation, giving the ability to offer a
range of Ethernet applications over a number of distances:
• 1000BASE-LX (Gigabit) Ethernet – up to 5,000m
• 10GBASE-LX4 & LR/LW (10 Gigabit) Ethernet – up to
10,000m
• 10GBASE-ER/EW (10 Gigabit) Ethernet – up to 22,250m
• 10GBASE-LR4 (100 Gigabit) Ethernet – up to 10,000m
• 10GBASE-ER4 (100 Gigabit) Ethernet – up to 40,000m
The result
As of April 2018, the various teams and businesses at the
TMA Toulouse campus established themselves in the B612
building. The new flagship of research and development for
the aerospace industry is fully up and running with an end-
to-end infrastructure solution that they can rely on. Currently,
there are 810 occupants including 500 SMEs, and these
figures are set to grow throughout 2018. n
