Hamamatsu introduces PIN photodiode for optical communications applications

29 October 2003 Bridgewater, NJ Lightwave -- Hamamatsu Corp. recently introduced the G9298 series of pigtailed Indium Gallium Arsenide (InGaAs) PIN photodiodes that feature high-speed performance with noise-free linear output. The G9298 series is well suited for design into optical communications devices and systems, including SDH/SONET and WDM, say company representatives.

The G9298 has high-speed response of 10 Gbits/sec and high gain of typically 5.5 kW. It also features a wide dynamic range of typically -19 dBm to +1 dBm. Typical sensitivity of the PIN photodiodes is 0.80 A/W at 1.3 mm and 0.85 A/W at 1.55 mm. The G9298 also has a low voltage requirement of only 3.3 V.

Hamamatsu has designed the G9298 series with a standard singlemode (9.5/125) fiber. It can be equipped with any of the four popular connectors--SC, FC, LC and MU--to suit any conventional design requirement.
