GigOptix announces production shipments of quad transimpedance amplifier receiver arrays to Kaiam for 40Gbps QSFP+ long reach module

SAN JOSE, USA: GigOptix Inc., a leading fabless supplier of semiconductor and optical components that enable high speed information streaming, has started volume production and shipments to Kaiam Corp., a private company commercializing photonic integrated circuits (PIC), of its HXR5104B, a quad Transimpedance Amplifier (TIA) receiver array for long reach 40Gbps QSFP+ applications.

GigOptix’s HXR5104B quad TIA is designed to be fully compliant with the IEEE 40GBASE-LR4 standard meeting the exacting receiver sensitivity and stressed eye requirements in addition to the 40Gbps QSFP+ form factor requirements. The solution is ultralow power, consuming less than 75mW/channel while fully implementing the receive function of a 10km 40Gbps link.

The quad channel integrated design includes 4 high sensitivity 10Gbps TIAs, an industry standard 2-wire digital interface to enable the full control of the device. The design minimizes the number of components required to implement the 40Gbps receiver resulting in a lower cost and smaller form factor. The HXR5104B further incorporates RSSI and based signal detect, among other features, while the programmable preemphasis circuitry facilitates optimal performance over various trace lengths.

Martin Bossard, the designer of the HXR5104B, and GigOptix’s director of HX Product Line Engineering and GM for GigOptix-Helix AG stated: "The HXR5104B was designed to provide a solution for the challenging 40GBASE-LR4 requirements leveraging GigOptix’s deep expertise in implementing parallel channel high speed low power solutions. GigOptix is excited to bring to market a solution that provides customers not only with a receiver amplifier with high sensitivity, but also with low cross coupling between the channels that enables it to pass the exacting stressed eye sensitivity requirements of the 40GBASE-LR4 specification in a really low power solution.

"Moreover, we are excited about the commercial potential of the HXR5104B, Ovum in its recent report on Optical Components report stated that the 40G QSFP+ LR4 market would grow from 17 thousand units in 2012 to over 350 thousand units in 2016 with a CAGR of 111 percent.”

Kaiam's QSFP-LR4 Transmit Optical Sub-Assemblies (TOSAs) and Receiver Optical Sub-Assemblies (ROSAs) enable high density 40Gbps links over single mode fiber for 10km links. At a quarter of the size of 40Gbps CFP modules, the QSFP is ideal for high growth datacenter, routing and switching applications.
