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)

Operators have found many reasons
to deploy G.657 fibres
Improved reliability
Smaller more aesthetically

• 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 peak and preserving 1625nm attenuation

AllWave+ and AllWave One fibresThe new industry standards for outside plant
14
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.
