Oclaro is sampling a suite of integrated optical components that enable transmission solutions up to 600 Gb/s per wavelength for long-haul, regional, metro and data centre interconnect applications.
Components in the portfolio include: a 64Gbaud micro-Intradyne Coherent Receiver (micro-ICR); 64Gbaud Integrated Coherent Transmitter (ICT); a 100kHz micro-integrated tunable laser assembly (micro-ITLA); 64Gbaud high-bandwidth co-packaged driver modulator (HB-CDM); and a high-bandwidth LiNbO3 polarisation multiplexed - quadrature Mach-Zehnder (PM-QMZ) modulator.
Micro-ITLA complies with the OIF micro-ITLA Implementation Agreement and uses the company’s thermally tuned DS-DBR laser technology to reduce low frequency phase noise and linewidth whilst increasing optical output power to above +17dBm, all contained in a reduced size footprint.
HB-CDM complies with the OIF HB-CDM Implementation Agreement and uses Oclaro's high bandwidth Indium Phosphide PM-QMZ modulator chip with a co-packaged matched RF driver. Flexible optical power and high linearity is achieved through the use of semiconductor optical amplifiers integrated within the InP modulator chip.
The high-bandwidth LiNbO3 PM-QMZ modulator is already released to production and shipping, and the 64Gbaud+ ICT combines a narrow line width laser with a high bandwidth PM-QMZ Mach Zehnder modulator to support flexible baud rates up to 64Gbaud and 64-QAM modulation. This enables transmission from 100 Gb/s to 600 Gb/s. Built-in SOAs, tunable filter and polarisation multiplexer eliminate the need for external optical components and simplify assembly while enabling operation in colourless networks. The ICT provides a local oscillator output with +12dBm EOL power for a mated coherent receiver.
The 64-Gbaud+ ICR is a fully integrated coherent receiver able to support flexible data rates from 100 Gb/s to 600G+. It supports rates up to 64Gbaud with modulation schemes such as 64-QAM. It features integrated MPD and VOA to support single channel and multichannel applications in colourless networks. It is compliant with the form factor specified in the OIF Implementation Agreement OIF-DPC-MRX-01.0.
Oclaro's suite of optical components is currently sampling, with the expectation that it will be in volume production by the end of this year.
