An optimized design of E/O and O/E for access points
of WiMAX RoF was carried out by evaluating RCE. The use of the
DFB-LD, a low input-impedance driving, a low distortion PIN-PD,
and a high gain EPHEMT amplifier is promising the cost-effective
design. For the uplink RoF design, the use of EDFA and EP-HEMT
amplifiers is necessity.
