2 for sure and probably more of Intel's main competitors will be receiving samples of POET's 100G and 200G CWDM4 Optical Engines beginning in early July.

Worth repeating from the June 8 news:

Powered by four flip-chipped 28G and 28G PAM4 CWDM (course wavelength division multiplexed) DFB (distributed feedback) lasers, the POET Optical Engines include an integrated athermal multiplexer and demultiplexer, 28G detectors, monitor photodiodes and bonding pads. Operating to MSA (Multi-Source Agreement) standards for the QSFP28 module, the POET Optical Engines will be available in chip sets for transmit only, receive only or in a combination transmit and receive single multi-chip engine less than 60mm square.

Built on a high resistivity 8” silicon wafer with low-loss, athermal waveguides, POET’s Optical Engines include passively-aligned active devices and superior thermal management.  These engines offer best-in-class coupling efficiencies, including to fiber attach units, and operate over a range of 500m to 10km under ambient operating temperatures of 0°C to 70°C. 

Based on the novel POET Optical Interposer platform, the 100G and 200G Optical Engines are fabricated entirely at wafer scale, offering unparalleled cost and size advantages. All engines are fully tested and burned-in prior to shipment. Super Photonics Xiamen, POET’s joint venture with Sanan IC, will be manufacturing the optical engines, with the capability to rapidly scale for customers with high-volume requirements.
