3S PHOTONICS Announces Successful 40Gbit/S Transmission Tests Of Its 1915 LMA Directly Modulated Analog Laser Module


3S PHOTONICS, world-leading French manufacturer of optical and optoelectronic components for telecommunications networks, recently announced the successful 32Gbit/s transmission over 20km of singlemode fiber without dispersion compensation using an AMOOFDM modulation of its new 1915 LMA Series of Next-Generation directly modulated 1550nm high bandwidth analog laser module.

This 1915 LMA prototype, presenting a 17GHz bandwidth and a +10dBm output power was tested by Orange Labs in Lannion (France) within the EPOD telecom project, sponsored by the French National Research Agency – ANR.

4 months after demonstrating a 19Gb/s transmission over 25 km using Discrete Multi-Tone modulation (DMT), fully satisfactory 40Gb/s back to back test and 32Gbit/s transmission over a 20km single-mode fiber link was experimentally demonstrated using Adaptively Modulated Optical OFDM signal (AMOOFDM) combined with a power/bit loading algorithm. The AMOOFDM signal contains 255 subcarriers spread over 12GHz. Transmission was achieved without any chromatic dispersion compensation and using a 35GHz bandwidth PIN-based receiver module for direct detection.

These very promising experimental results reinforce the credibility of using OFDM modulation applied on a directly modulated analog laser module as a key contributor to design the Next-Generation of low cost broadband optical access networks.

3S PHOTONICS – formerly Alcatel Optronics – is the leading world manufacturer of laser chips, optical discrete modules and components for undersea telecommunication networks. It designs, develops, manufactures and commercializes active components powered by in-house III-V optoelectronic chips based on both Gallium Arsenide (GaAs) and Indium Phosphide (InP) technologies and passive components using Fiber Bragg Gratings (FBG).

The 3S PHOTONICS renowned optoelectronic chip manufacturing plant of Nozay is a technological feat that is unique in the world as it brings together GaAs and InP technologies under the same roof.

Its product portfolio includes five product lines:

  • Transmission Laser and Detector Modules
  • Pump Laser Modules for terrestrial and submarine applications
  • Chromatic Dispersion Compensation Modules
  • Filters, gain equalizers and pump stabilizers based on Fiber Bragg Gratings for terrestrial and submarine applications
  • Chips (lasers and detectors) and Front End Services

With over 15 years of experience, the company takes advantage of its expertise and know-how to also address new markets, providing smart solutions for defense, industrial and medical applications.

Based in Nozay (near Paris, France), 3S PHOTONICS is run by Alexandre Krivine and Didier Sauvage. The company employs over 160 people, of which 130 are experts in the photonics industry. For more information about 3S PHOTONICS, visit:
