Satisfy 5G Data Transmission Capacity Demand With a

New-generation Fiber

In order to allow multicore fibers to be
deployed quickly and easily for industrial
application, InPhoTech has created a fiber

design ready for implementation in existing
networks. A complete system based on
InPhoTech’s IPT-CORE consists of a 7-core
or a 19-core passive optical fiber together
with fan-in/fan-out components on both
ends of the fiber.

5G communication is clearly a leading trend in the telecom industry
today. This new reality of connecting all and everything is in the
air – but not only there. 5G mobile communication is expected
to support the transmission of much larger volumes of data
with much lower signal latency than the former generation. This
imposes extreme requirements in terms of transmission capacity
on the wireline part of the transport network – the telecom grid
critical for supplying each 5G radio-base-station or antenna
mast. This grid functions using millions of kilometres of optical
fiber cables that have to support both the ongoing incremental
increases in transmission requirements as well as extreme peak
demands like that recently caused by the COVID-19 pandemic.

The most obvious way to increase the capacity of optical fiber Business and Technology Development Manager
systems is to deploy cables with higher fiber counts. However, a InPhoTech, Poland
less evident problem emerges, especially in highly dense urban
areas: the existing infrastructure is not capable of accommodating
a larger number of optical fiber cables. There are two main reasons
for this. Firstly, the capacity of cable ducts is limited, resulting in
massive cost increases for new cable installations; and secondly,
optical fiber telecom systems need to follow the trend towards
miniaturization and integration in current technology.

There remains only one efficient, unexplored dimension for
increasing fiber capacity, and that is adding more spatial channels
in a single fiber strand. Each such channel – or core – shall
perform as a single-core fiber in terms of transmission properties
and be fully compliant with legacy fiber installations and active
equipment.
