* Fifty gigabit Passive Optical Network (PON) technology will be a crucial support for 5G
* Work started on standards early last year and now Huawei says it has a demo prototype
* The standards are to be completed next year with commercial product arriving in 2023

Just before MWC we noted that what we should be seeing and hearing at Mobile World Congress was a greater emphasis on transport network technology.

The logic was that the radio part of the 5G piece is now well advanced with NR over 4G poised to serve first generation 5G devices in and beyond 2020 year or so. Surely now is the time to at least start talking to the broad market about the new transport technologies capable of supporting the flavours of 5G promised from the mid-2020s - the big bandwidth, low latency 5G that will surface all those new use cases. That won’t happen without an agile, software driven transport network.

One player keen to make a bit of a splash on transport (in fact keen to push its profile on everything at the moment for obvious reasons) was Huawei, which actually released a 50Gbit/s Passive Optical Network (PON) prototype at MWC.

As it perhaps anticipated, the announcement and demo hardly made a ripple when it landed in the MWC news pool, so Huawei went and announced it again in 2019 year.It says it’s hatched the world's first single-wavelength 50G passive optical network (PON) prototype.

What? Why?
In February 2018, the ITU-T officially initiated the 50G PON standards project and began developing technical solutions and standards which are expected to be finalized in 2020 and put into commercial use in 2023.

Fifty gigabits per second is more than a speed ramp, although that sort of single wavelength performance is very important. It means that a fibre-wielding telco can have five times the downstream bandwidth at its disposal to keep up with data demands to businesses and homes and to accommodate all the streamed video that users appear to want to consume.

But a 50G PON means you can engineer lower latency. Huawei maintains that the prototype, which can provide 50 Gbps downstream and 25 Gbps/50 Gbps upstream transmission rates over a single wavelength, demonstrates that next-generation PON technology is now mature enough to begin focusing on 5G product development. This, it says, must be a welcome confidence boost for the 50G PON industry.

In the end there are only two generalised ways you can tackle latency in the network (latency introduced by the mobile applications are another thing again). First you can decrease the light journey across the fibre (edge computing can improve that) and second, you can optimize things like clock synchronization and data processing at each end of the PON. You can’t tangle with the speed of light of course (that would probably require a strategic partnership with Dr Who) but you can work on innovation to conquer synchronization problems.

Geehe is still devote to developing and manufacture relative products for 5G, the main and top rated items are fiber passive optic products and optic splitters,couplers etc.

PLC splitter or planar lightwave circuit splitter is a passive component that has the special waveguide made of planar silica, quartz or other materials. It is employed to split a strand of optical signal into two or more strands. PLC splitter also has lots of split ratios, and the most common ones are 1:8, 1:16, 1:32, 1:64, 2:8, 2:16, 2:32 and 2:64. There are many types of PLC splitters to meet with different needs in OLT and ONT connection and splitting of optical signals over FTTH passive optical networks. There are seven major package types of PLC splitters according to different applications, i.e. bare fiber splitter, module splitter, rack-mount splitter, Mini Type splitter, Tray splitter and LGX splitter.

Bare fiber optical splitter
ABS splitters
Mini Type fiber splitter
Tray splitter
Rack-mount splitter
LGX splitters
PLC splitter in mini plug-in type


Bare Fiber PLC Splitter

Bare fiber PLC splitter has no connector at the bare fiber ends. It can be spliced with other optical fibers in the pigtail cassette, test instrument and WDM system, which minimizes the space occupation. It is commonly used for FTTH, PON, LAN, CATV, test equipment and other applications.
