This paper proposes a cost‐effective hybrid‐type power budget extender (PBEx) that can provide a high power budget of over 45 dB in an asymmetric 10‐Gb/s Ethernet passive optical network (10/1G‐EPON). The hybrid‐type 10/1G‐EPON PBEx comprises a central office terminal (COT) and remote terminal (RT) module supporting four channels and uses a coarse wavelength division multiplexing (CWDM) technology between the COT and RT for a reduction of fiber cost and efficient access network design. The proposed 10/1G‐EPON PBEx can provide over a 40‐km reach and 128‐way split per CWDM wavelength with no modification of a legacy 10/1G‐EPON system and can satisfy the error‐free service in 10 10 packet transmission.
