Widely tunable laser produces more power
High-power tunable laser for DWDM networks has an output power of 40mW and other features ideal for DQPSK coding and 40Gbit/s systems.
New from NeoPhotonics at OFC is a high-power tunable laser for DWDM (dense wavelength division multiplexing) networks that has an output power of 40mW and other features ideal for DQPSK coding and 40Gbit/s systems At 40mW optical output power, the NeoPhotonics widely tunable NTL2040 laser can transmit at twice the output power of a standard ITLA

GPON transceivers comply with latest specs
NeoPhotonics has released a full line of GPON transceivers compliant with the ITU-T G.984.2 Class B+ standard to augment its portfolio of widely deployed FTTx biplexer and triplexer modules.
Add/drop modules integrate more
NeoPhotonics has announced the general availability of its 40-channel reconfigurable optical add/drop module with per channel variable optical attenuators and power monitoring.
Special coding used in some 40Gbit/s transmission requires higher optical power to overcome higher loss from additional optical components.
In addition, 40Gbit/s systems are much more sensitive to dispersion than 10Gbit/s systems and require narrower linewidths and higher side mode suppression ratios (SMSR).
The external cavity design and output power of the NeoPhotonics NTL 2040 laser results in a narrow linewidth, low noise, high SMSR and high 40mW power.

NeoPhotonics' OLT and ONU devices offer a complete line of pluggable transceivers to GPON systems manufacturers.
The NTL2040 laser also enjoys all of the advanced features of NeoPhotonics NTL2000 series tunable lasers and can address all commonly used wavelengths in DWDM systems in the C, C+, L and XL bands, with channel spacing based on the "ITU-T" specified 50GHz grid.
Thus, one NTL2000 series tunable laser can replace any of 120 single wavelength lasers in the C+ or XL bands.
As a result, the NTL2040 laser enables 40Gbit/s transmission while also reducing the complexity and cost of systems design and lowering the cost of sparing and inventory.
"We believe that system vendors and carriers are moving rapidly to design and deploy 40Gbit/s DWDM systems", says Tim Jenks, Chairman and CEO of NeoPhotonics.
"Due to its high output power, narrow linewidth, and low noise, we believe that our new NTL2040 tunable laser will allow these vendors to enjoy the benefits of wide, fast tunability in their 40Gbit/s applications".
The NeoPhotonics NTL2000 series uses a continuous wave (CW) external cavity laser delivering high spectral purity with low RIN, low SMSR and narrow linewidth.
The output power is adjustable with standard outputs of 10, 20 and 40mW.
It is suitable for most DWDM applications, including metro, long-haul and ultra long-haul, and datarates from 2.5 to 40Gbit/s.
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.
