The transport capacity of fiber-optic communications systems over ultralong-haul (UHL) distances has been significantly increased in recent years by technologies such as the EDFA, WDM, dispersion compensation, and forward error correction (FEC). The omnipresent on/off-keying (OOK) modulation format in conjunction with direct detection has worked very efficiently for data rates up to 10 Gbits/sec per WDM channel....
