SEPTEMBER 14, 2007 — Hamamatsu Photonics introduced an InGaAs APD receiver, G8931-20, that it claims exhibits higher sensitivity than conventional InGaAs PIN photodiodes.
The component offers gain of greater-than or equal-to 10× and sensitivity at 8 A/W for 1550 nm. A 0.2-mm-diameter active area is said to enable easier coupling to optical fiber, and increased sensitivity.
The G8931-20 can be supplied with a fiber-optic pigtail or a standard fiber connector type, such as SC/SPC or FC/SPC. Applications include range finding, free-space optical communications OTDR, and other fiber-optic areas.
