Pragmatic approach is needed
Perhaps no silver bullet …
… but what are the optical layer options?
Best latency Highest capacity per
fiber and low latency
TDM-PON
Grey point-
to-point links DWDM
Best-effort traffic

So what does all this mean?
Pragmatic approach to
building RAN networks
Ethernet makes our life
simple and “easy”
Standards to set the
baseline of transport
Timing/sync becomes
increasingly important
Disaggregation or
openness in RAN is
future proof
Know-how from
application, protocol to
transport layer, to offer
turnkey solutions
