Macom has introduced transimpedance amplifiers for optical comms ranging from 100Gbit/s DR1 to 800Gbit/s DR8 and FR8.

There are two parts, which come in flip chip and wire bonding packaging options for deployment in QSFP, QSFP-DD and OSFP optical modules.

• MATA-05817 has noise typically below 2μArms and supports bandwidth up to 35GHz. It is aimed at high density optical data center interconnects – for 50G, 100G, 200G and 400G receivers using multilevel modulation such as PAM4.
• MATA-38134 is a quad 26/53Gbaud linear PAM4 amplifier with automatic gain and integrated AGC loop. It is primarily aimed at single-mode fibre applications. The 0.5mm anode to anode spacing is intended to allows two devices to be placed within a QSFP-DD form factor for 800Gbps applications.

“The rapid evolution to single lane 100G and multiple lanes 200G, 400G and 800G connectivity is increasing the demand for high-performance, power-efficient optical components needed to maximize bandwidth density in the cloud data center,” according to the company.

Both devices include RSSI for photo-alignment and power monitoring and I2C control of bandwidth, output amplitude, peaking, LOS, gain and other parameters.

Electronics Weekly has asked Macom more information on these devices.
