Optical component and subsystem developer Oclaro, Inc. (NASDAQ: OCLR) reveals it is now sampling a dual micro-ITLA that offers a 25% smaller footprint and 1 W lower power consumption versus two discrete micro-ITLAs. The company expects to begin volume production of the device next month.
The dual micro-ITLA enables designers to use either a separate laser for transmit and local oscillator for 100G/200G designs or leverage the device's high output power in dual-carrier applications for next-generation 200G/400G coherent transmission links. Regardless, the dual micro-ITLA will save board space on line cards and reduce power requirements, Oclaro says.
The device leverages Oclaro's DS-DBR wideband tunable laser technology, which is based on a fully monolithic Indium Phosphide (InP) chip. The dual micro-ITLA therefore has no moving parts; its low-voltage, electrical tuning ensures rapid wavelength switching, Oclaro says.
Performance specifications include:
- Full C-Band dual-laser tunable source (1529 -1568nm)
- +15.5 dBm nominal EOL and variable output power range of 8 dB
- 0.1-GHz minimum channel grid spacing and electronic shutter for dark tuning
- Power dissipation of 8 W EOL
- Narrow line-width, 400 kHz maximum, SMSR >40 dB, and low RIN.
Oclaro believes its new product will find application in 200G and 400G coherent transmission designs.
"Many of our customers are already completing 400G trials, and Oclaro components will be there with the performance, power and size requirements needed to accelerate the deployment of these next generation networks," promised Richard Craig, president of Integrated Photonics Business at Oclaro.
