3S Shows Off Laser Prototype

NOZAY, France -- 3S PHOTONICS, world-leading French manufacturer of optical and optoelectronic components for telecommunications networks, today introduced its 1915 LMA Series of Next-Generation directly modulated 1550nm high bandwidth analog laser modules optimized for OFDM / QAM [1] modulation formats.

Specifically developed by 3S PHOTONICS for the EPOD[2] telecom project, sponsored by the French National Research Agency - ANR -, this low RIN 10mW 1550nm analog laser module enables the transmission of analog signals within an ultra-wide bandwidth from 10MHz to 20GHz.

This module is intended for the distribution and/or the transmission of radio-type signals thru broadband fiber links such as Radio-over-Fiber (RoF), RF over Glass (RFoG) or Fiber-to-the-Antenna (FTTA) applications.

“When directly modulated with OFDM technique – the one implemented in xDSL transmission -, the 1915 LMA represents a perfect transmitter candidate for the Next-Generation of broadband optical access networks, meeting all the stringent requirements set by the convergence of metro and access, i.e. low cost, mature technology, high bit rate and extended reach”, claims Yannick Bailly, VP Marketing and Product Management at 3S PHOTONICS.

“We have developed this 1915 LMA prototype under the EPOD project. Purpose was to try to imagine what the Next-Generation access networks could or should be to overcome the expected bandwidth bottleneck due to the emergence of new Internet services. With our partners within EPOD, we have explored the transmission performances of our 1915 LMA analog laser modules through the use of OFDM modulation format. Objective being to take part to the evolution of access networks providing low-cost high performance optoelectronic technologies. 1915 LMA development is a key step forward for this project“, explains Didier Sauvage, member of the board and CTO of 3S PHOTONICS.
