Kaiam offers flattop Mach-Zehnder Athermal AWG for 5G fronthaul

Planar lightwave circuit (PLC) device and transceiver developer Kaiam it has made available a line of ultra-low loss Mach-Zehnder Athermal AWGs (MZ-AAWGs) targeted at industrial temperature 5G fronthaul requirements. The company says the MZ-AAWGs display a flat passband with almost zero loss using the on-chip combination of Mach-Zehnder and AAWG technology, says the company.

Planar lightwave circuit (PLC) device and transceiver developer Kaiam it has made available a line of ultra-low loss Mach-Zehnder Athermal AWGs (MZ-AAWGs) targeted at industrial temperature 5G fronthaul requirements. The company says the MZ-AAWGs display a flat passband with almost zero loss using the on-chip combination of Mach-Zehnder and AAWG technology, says the company.

Kaiam says it achieved such performance by synchronizing the Mach-Zehnder with the AAWG. The device offers a level of loss comparable to the peak of a Gaussian AAWG, but over a much wider passband, says the company. The MZ-AAWG will operate over the industrial temperature range of -40C to +85C. Kaiam says it has already begun delivering the device in production volumes.

The company notes that the technology can be used in a cyclical manner to address different ITU bands/channel plans for upstream and downstream traffic.
