Due to power restriction of some laser sources, the use of same optical power in every bit duration (i.e., same bit power) of double-weight codes in optical code-division multiple access (O-CDMA) with differential quality-of-service (QoS) was previously studied and analyzed with approximated performance. In this paper, an exact analytical model is formulated and validated with computer simulation, establishing accurate relationships of code weight, chip power, and bit power with code performance. Besides better understandings the role of power control in variable-weight O-CDMA with differential QoS, such accurate analytical model is important for power-sensitive applications, such as in-service monitoring and fiber-fault surveillance in optical networks and sensor-identification in fiber-sensor systems with the use of optical codes.
