An innovative 10 Gbit/s single mode optical transmitter with the capacity of error‐free transmission is demonstrated in the range of 0–100 km with constant biasing conditions by using a quantum dash directly modulated laser. A commercially available etalon filter is used as a passive optical filter to achieve penalty‐free transmission with a dynamic extinction ratio >6 dB over a large range of fibre spans.
