Nts'etsopele ea li-module tsa puisano tse se nang mohala: marang-rang a 5G, 25G / 100G li-module tsa optical ke mokhoa.

Kaho ea marang-rang ea 3G e qalile ka 2008-2009, 'me tlhokahalo ea li-base station optical modules e ile ea nyolohela ho 6G.
Ka 2011, lefats'e le ile la kena kahong ea marang-rang a 4G, le li-modules tse ka sehloohong tsa 10G tse sebelisoang ho prequel.
Ka mor'a 2017, butle-butle e fetohile ho marang-rang a 5G 'me ea tlolela ho 25G / 100G optical modules.Marang-rang a 4.5G (ZTE e bitsa Pre5G) e sebelisa li-module tsa optical tse tšoanang le tsa 5G.
Papiso ea meralo ea marang-rang ea 5G le meralo ea marang-rang ea 4G: Nakong ea 5G, eketsa karolo ea phetisetso, ho lebelletsoe hore tlhoko ea li-module tsa optical e tla phahama.
