Abstract: We propose a dual-band tunable transmitter for WDM-PON. The transmitter has a versatile function of both tunable OLT source and tunable line monitoring source of OTDR on a single optical platform. The performance of dual-band OLT transmitter using self-locked RSOA is experimentally evaluated and has more than 10 nm tuning ability.

Abstract. Nowadays, optical networks are becoming dense while detecting faulty branches in the tree-structured networks has become problematic. Conventional methods are inconvenient as they require an engineer to visit the failure site to check the optical fiber using an optical time-domain reflectometer. An innovative monitoring technique for treestructured network topology in Ethernet passive optical networks (EPONs) by using the erbium-doped fiber amplifier to amplify the traffic signal is demonstrated, and in the meantime, a residual amplified spontaneous emission spectrum is used as the input signal to monitor the optical cable from the central office. Fiber Bragg gratings with distinct center wavelengths are employed to reflect the monitoring signals. Faulty branches of the tree-structured EPONs can be identified using a simple and low-cost receiver. We will show that this technique is capable of providing monitoring range up to 32 optical network units using a power meter with a sensitivity of −65 dBm while maintaining the bit error rate of 10 −13 .
