MACOM launches 226Gbps per lane products for 1.6TB optical modules

At #OFC23, MACOM introduced its 226Gbps per lane technology product family for enabling 1.6TB optical modules.

The product family includes MACOM transimpedance amplifiers MATA-40734 and MATA-40736, Externally Modulated Laser (EML) driver MAOM-011112 and photodiode MARP-BP112. 

The TIAs allow for a data rate of up to 226.8Gbps per lane to support KP4 and IEEE concatenated Forward Error Correction (FEC) with 750um spacing to photodetectors to minimize channel-to-channel cross talk. TIAs for both wire-bonded and flip-chip applications are available. 

The EML driver is a single-channel flip-chip device enabling ultra-low inductance interfaces for optimum performance and minimum size in an optical module design. Its high bandwidth and high swing can help deliver industry-leading optical performance. 

The photodiode is also a flip-chip design with high responsivity and an integrated lens for improved alignment tolerance. It is available in both singlet and array form factor.
