The operation of an extended power budget long reach access network is experimentally demonstrated using commercially available small form pluggable directly modulated transmitters and a simplified coherent receiver free from digital signal processing and phase‐locked loops. An ad‐hoc choice of photodiode bandwidth allows no penalty compared with external modulation based transmitters.
