  Today, deployment of optical fiber has offered large transmission capacity
which cannot be efficiently utilized by the electronic switches. Rather,
Integrated Hybrid Optical Network (IHON) is a promising approach which combines
both packet and circuit switching techniques. As a result, it achieves
efficient utilization of the bulk capacity and guarantees absolute Quality of
Service (QoS) by optimizing the advantages of the two switching schemes while
diminishing their disadvantages. Transpacket has developed a Fusion node
implementing IHON principles in Ethernet for the data plane. Hence, this paper
investigates and evaluates IHON network for 5G access networks. The simulated
results and numerical analysis confirm that the Packet Delay Variation (PDV),
Delay and Packet Loss Ratio (PLR) of Guaranteed Service Transport. (GST)
traffic in IHON network met the requirements of 5G mobile fronthaul using CPRI.
The number of nodes in the network limits the maximum separation distance
between Base Band Unit. (BBU) and Remote Radio Head (RRH), link length; for
increasing the number of nodes, the link length decreases. In addition to this,
we verified how the leftover capacity of fusion node can be used to carry the
low priority packets and how the GST traffic can have deterministic
characteristics on a single wavelength by delaying it with Fixed Delay Line
(FDL). For example, for LSM 1GE=0.3 the added Statistical Multiplexing (SM)
traffic increases the 10GE wavelength utilization up to 89% without any losses
and with SM PLR=0.001 up to 92% utilization.
