Voxtel Inc.BEAVERTON, Ore., April 5, 2010 — Voxtel Inc. has announced the release of a near-infrared avalanche photodiode (APD) receiver with 1-GHz bandwidth and a large 200-µm-diameter optical area. Suitable for laser rangefinder, laser designator, free-space optical communications, optical instrumentation and ladar/lidar applications, it is the latest entry in the company’s Siletz line of back-illuminated single-carrier multiplication avalanche photodiode (SCM-APD) products. The receiver integrates the low-excess-noise SCM-APD with a low-noise transimpedance amplifier. The NIR/SWIR (short wavelength infrared) APDs...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/23/2024OSFP TransceiverThe OSFP 800G SR8 from Approved Networks is a 800G OSFP transceiver meant for supporting data-intensive applications and enable real-time AI processing across networks for data centers and broadband...Photonics.com 7/15/2022Fiber Optic Network SimulatorThe Fiber Lab MSP fiber optic network simulator from M2 Optics Inc. simulates several common fiber optic links in a single unit for training, demonstration, and testing applications.
