1. Increase baud rate
Increase baud rate
Use a more advanced coding method (PAM4)
2. Increase the number of fiber cores
Using MPO / MTP connectors (MPO-12, MPO-24, MPO-16, MPO-32)
3. Increase the number of wavelengths and use better fibers
Wavelength Division Multiplexing CWDM / DWDM / SWDM
Use better fiber
