Reflective Semiconductor Optical Amplifiers (RSOAs) offer a cost effective wavelength agnostic transmitter for applications within wavelength division multiplexed passive optical networks (WDM PONs). The parametric and systems performance of bulk active buried heterostructure RSOAs across the S, C and L wavelength bands is given.
Passive optical networks are being aggressively pursued as a means of delivering access network solutions. The cost benefits resulting from reducing the number of interfaces between nodes has enabled increasing deployment of passive optical network delivering fibre to the home and fibre to the kerb. However, in many cases, the need for high split ratios or extended reach requires some form of amplification...
A 1300 nm semiconductor optical amplifier has been developed for extended reach GPON applications. The high gain of 29 dB has and enabled a commercial GPON system to operate over 60 km and with 128-way split.
