“…[17][18][19], the monitoring system should be simple, cost-effective, non-invasive to data traffic and compatible with different PON topologies. Several real-time online fault monitoring systems have been reported, with traditional optical time domain reflector (OTDR) assisted by other devices or mechanisms, e. g., fiber Bragg grating (FBG) [20], high-pass filter [21], optical encoders [22], or the Brillouin frequency shift generated in the branch fibers [23]. Although they comply with some of the requirements, they remain complex and costly.…”

“…Some of these solutions either impose significant technical challenges or impractical due to their limited capacity [10][11][12][13]. A new technology to monitor the optical access network is to use optical codes as identifiers for the customer branches, exploited to identify the fault in the network [14].…”

Feeder OC2 CO RN 1000100010001000 U band short-pulse OC1 1 1 1 1 Monitoring OLT Fig. 1. Optical coding monitoring system.Abstract-A novel ring encoder for passive optical network (PON) is proposed and analyzed in term of SNR and probability of false alarm (PFA). The encoder exploits a fiber ring and one Bragg grating to produce a multi-level periodic code. We obtain an SNR of 10 dB for 256 customers in 10ms measurement time with 20km traditional PON. For 100km long reach PON (LR-PON), we obtain an SNR of 10dB for 64 customers in very high 1.7 minutes measurement time. We also apply Neyman-Pearson testing to the receiver and we investigate how the network size affects the operational expenses of our monitoring system. We illustrate the receiver operating characteristics (ROCs) of the system showing the tradeoff between the detection and false alarm probabilities. We show that 95% detection probability (PD) for 128 traditional PON customers can be achieved with 0.006 false alarm probability (PFA) in 2ms measurement time which is 50 times smaller than PFA when averaging is not used.Index Terms-FTTH, PON, optical network monitoring, signal to noise ratio, false alarm probability.
