Annual Demand of G.657 fibres continue to grow
Europe is adopting these fibres
faster than the rest of the
world!
•
World wide 8% of all
deployed fibre is G.657
•
Europe 13% of all deployed
fibre is G.657 (over 60%
greater)

Traditional use for G.657 Single-mode fibres:
Access network
Connectivity and
In building
ITU-T G.657
Operators have found many reasons
to deploy G.657 fibres

Improved reliability

Smaller more aesthetically
pleasing connectivity

Increased fibre density

Simplified installations
Expected that growth of G.657 fibres in
access network will continue

Why is Europe leading the way with Bend
insensitive Single-mode fibre offers?
•
Congested ducts and high count
cables
•
Micro Cables can benefit from
improved macrobend performance
•
Smaller and more aesthetically
pleasing connectivity
•
Full Spectrum means low water

AllWave+ and AllWave One fibres
The new industry standards for outside plant
AllWave + fibre - the first choice for outside plant FTTx, Access
and metro applications
– Reliability for full spectrum
– Seamless splicing – fewer calls from the field
– Improved macrobend performance (benefit higher transmission
wavelengths)
AllWave One fibre - for longer links where low loss is also required
– Reliability for full spectrum
– Seamless splicing – fewer calls from the field
– Improved macrobend performance (benefit higher transmission
wavelengths)
– Lower loss

Summary
•
Rapid growth in G.657 fibres
•
Europe has adopted G.657 fibres faster than the rest of the
world
•
Value of G.657.A1 fibres is not only in the access network
but also Metro and long haul networks
•
Next major growth will be G.657.A1 fibres with 9.2 MFD and
when required lower loss.
