Sub-assembly with 4.25Gbps responseHamamatsu Corp. introduced the G9735-14 receiver optical sub-assembly (ROSA) that combines a Gallium Arsenide (GaAs) PIN photodiode and preamp to create an integrated solution in a 1.25mm diameter sleeve. With a response of 4.25Gbps and operating at the 850nm wavelength, the product has been developed for design into fiber channel applications.

Response for the G9735-14 is typically 0.6 A/W, while sensitivity typically ranges from 2dBm to -22dBm. The ROSA has typical optical return loss of 13.5dB, typical dark current of 0.05nA, and typical trans-impedance of 1 kiloohms. Noise equivalent power is typically 660nWrms for the G9735-14. Designed with a differential output, the G9735-14 has typical output impedance of 50?.

The G9735-14 is priced at $108 each in small quantities. Delivery in 5 to 6 weeks.
