A DWDM self-seeded source achieves transmission in the O-band up to 90km SSMF at 2.5Gbps. Moreover, a “face-to-face” self-seeded architecture permits to realize transmissions at 2.5Gbps with extra-long optical cavities reaching 70km of SSMF.
In this paper, we experimentally demonstrated a self-seeded wavelength-division-multiplexed passive-optical-network (WDM-PON) based on a high polarisation dependent gain reflective-semiconductor-optical-amplifier (RSOA). The experimental results show a possibility of implementing a WDM-PON with 16 channels of 100 GHz channel-spacing at 2.5 Gbit/s for a reach of 60 km. Considering FEC error-free transmission...
This paper describes the technical aspects of optical access solutions for mobile fronthaul application. The mobile context and main constraints of fronthaul signals are presented. The need for a demarcation point between the Mobile operator and the Fiber provider is introduced. The optical solution to achieve such a network is discussed. A WDM network with passive monitoring at the antenna site and...
A self seeded WDM PON solution is evaluated at 1.25Gb/s and 2.5Gb/s in order to address optical budget, rise and fall time and jitter performances issues.
DWDM sources based on self seeded-RSOAs (SFP packaged) are experimented to bring easier usage in metropolitan networks. An optical budget of 26.5dB is realized with 50km of fiber and is further extended up to 60dB and 120km with an EDFA.
An external cavity laser is demonstrated with a RSOA at ONU and a mirror at the RN which can be 5km away. A record transmission of 10Gbits/s is shown and compared with performance at 1.25, 2.5, 5Gbit/s.
Control of chirp parameter in a fully integrated EML-SOA chip based on InGaAlAs MQW technology is investigated. Transmission at 10 Gbit/s over 100 km of conventional SMF was obtained by optimizing signal chirp at emission.
We experimentally investigate a cost-effective upstream transmitter for WDM PON using external cavity laser based on reflective semiconductor optical amplifier. The laser can be directly modulated and shows good performance at 1.25 and 2.5 Gb/s.
