Hamamatsu Introduces Highly Reliable ROSAs For Design Into XFP Transceivers

G9911-14/-54 InGaAs PIN Photodiodes Deliver High Performance and are Compatible with 10 Gbps Miniature Devices

Bridgewater, NJ — Hamamatsu Corporation introduces the G9911-14/-54 receiver optical sub-assemblies (ROSAs) that have high-speed response, high trans-impedance, low optical return loss, and excellent sensitivity. Compatible with 10 Gbps Miniature Devices (XMD), the G9911-14/-54 are designed for use in XFP transceivers, as well as SONET/SDH network applications.

The G9911-14/-54 are Indium Gallium Arsenide (InGaAs) PIN photodiodes with typical sensitivity ranging from +2 dBm to -20 dBm at 1.55 um. They have high trans-impedance of typically 6 kOhms and low optical return loss of typically 35 dB at both 1.31 um and 1.55 um. Typical response is 0.85 A/W at 1.31 um and 0.9 A/W at 1.55 um, and the G9911-14/-54 have typical dark current of 0.05 nA.

Requiring only 3.3 V, the G9911-14/-54 are low power devices that provide flexibility in design of XFP transceivers. The G9911-14 has a pin design while the G9911-54 incorporates a flex board interface for space-restricted designs.
