NeoPhotonics Corp., a leading supplier of optical components for the telecom and CATV industries, will debut at ECOC (the European Conference on Optical Communications in Berlin, booth 15031, September 17th ¡V 19th) a new tunable laser for DWDM (dense wavelength division multiplexing) networks that performs the functions of any of 200 single-wavelength lasers.
Offering 80 nm tuning range, NeoPhotonics¡¦ ultra widely tunable NTL2000 laser can transmit virtually the same output waveform at every frequency in the C-band, L-band, extended L-band (XL-band), or both C+L bands (tuning over 80 nm with channel spacing based on the ¡§ITU-T¡¨ specified 50 GHz grid). This means that a single NeoPhotonics NTL2000 laser can address all commonly used wavelengths in DWDM systems and essentially do the work of any of 200 single wavelength lasers. As a result, the NTL2000 laser reduces the complexity and cost of systems design and lowers the cost of sparing and inventory management for both network equipment manufacturers and their network operator customers. An ultra-wide tuning range plus adjustable optical power makes the NeoPhotonics ITLA (integratable tuner laser assembly) product a ¡§universal DWDM laser¡¨ for most optical transport applications.
The NeoPhotonics design uses a continuous wave (CW) external cavity laser delivering high spectral purity with low RIN, low SMSR and narrow line width. The output power is adjustable with standard outputs of 10mW and 20mW. It is suitable for most DWDM applications, including metro, long-haul and ultra long-haul, and data rates from 2.5G to 40G. The laser has fast wavelength tuning to meet the standards for SONET/SDH and DWDM protection switching, dynamically reconfigurable networks and remote provisioning and testing.
The simple, proprietary design with no moving parts, standard off-the-shelf components and efficient, low cost manufacturing provides for performance, reliability and cost advantages. The laser module integrates a butterfly package with all of the requisite drive and control electronics into an OIF MSA compliant ITLA module
¡§We believe that there are an increasing number of system vendors and carriers switching to widely tunable laser based transmitter designs and, at the same time, we are seeing good growth in the global DWDM marketplace,¡¨ said Tim Jenks, Chairman and CEO of NeoPhotonics. ¡§Due to its narrow linewidth, we believe that our new tunable laser will be particularly useful in 40 Gbps applications.¡¨
