Laser is optimised for speedy
short-range comms
The OL5157M is a 40Gbit/s electro-absorption modulated laser for the VSR (very short reach) optical transporter market.
New from Oki Electric, the OL5157M is a 40Gbit/s electro-absorption modulated laser (EML) for the VSR (very short reach) optical transporter market By optimising the matching between EML and the 40Gbit/s broadband driver amplifier provided by Narda, an L-3 Communications company, this solution enables system designers to reduce the bit error rate (BER) in data transport

More power from laser modules for WDM systems
Oki Electric has developed a trio of high-power 1480nm pump laser diode modules for WDM (wavelength division multiplexing) optical transmission.
"This is a solution that reduces the time and cost our customers spend in testing the combination of EA modulators and amplifiers to convert electric signals into optical signals".
"Thus, provides an optimum solution in building a 40Gbit/s VSR transmitter for high capacity networks", said Masayuki Tsuboi, President of Optical Components Company at Oki Electric.
"With this solution, which will be available to the worldwide 40Gbit/s VSR transponder market, our customers can easily manufacture high-quality transmitters".
Oki's OL5157M integrates a 1.5mm distributed feedback (DFB) laser and an EA modulator into a single chip, and is equipped with DC bias circuit, with features of 5dBm CW high optical power output, dynamic extinction ratio larger than 9dB at 40Gbit/s, and operates under a low modulation voltage of 3V peak-peak.
This OL5157M is optimised with Narda's GaAs IC module (FO-MDA-40-13), which is capable of datarates to 44Gbit/s that comes with V or GPPO type connector, has an output voltage adjustable in the 2.5 to 4V peak-peak range, and has a built-in electronic circuit for crosspoint control to optimise the optical eye diagram.
By optimising Oki's OL5157M and Narda's FO-MDA-40-13, the two companies provide a solution that significantly improves the major problem of high frequency matching performances.
This solution thus enables lower jitter and reduces BER, which as a result, provides the best-suited transmission quality for a 40Gbit/s VSR optical transmission multisource agreement (MSA) transponder.
