Commercial Metals Company Innovates with New High-Gain Low-Noise InGaAs APD Family
Commercial Metals Company (CMC) Electronics marks a significant advancement in optical technology with the launch of its 767 Series Pigtailed High-Gain Low-Noise InGaAs Avalanche Photodiode (APD) family. Designed to cater to critical applications in detection, defense, and communication, this innovative product line addresses the growing demand for high-performance devices in various sectors. The 767 Series is particularly proficient in challenging tasks such as Optical Time-Domain Reflectometry (OTDR), Distributed Temperature Sensing (DTS), and Laser Range Finding (LRF), making it an essential tool for industries reliant on precise measurements and data collection.
The 767 Series includes the 276-339767-VAR model, which offers two active area variants: 30 µm for single-mode fiber (SMF) and 80 µm for multimode fiber (MMF). Both variants are engineered to deliver a high operating gain exceeding M = 100, along with a low k-factor and a minimal Excess Noise Figure (F). These specifications highlight CMC Electronics' commitment to developing devices that maintain high dynamic range and quantum efficiency across a wavelength range of 950 to 1600 nm, even under elevated temperature conditions. This capability significantly reduces the need for cooling, a critical factor in ensuring optimal device performance in various operational environments.
Éric Desfonds, Senior Technical Applications Manager at CMC Electronics, emphasizes the strategic design of these APDs, noting their very low excess noise. This feature allows for enhanced gain and dynamic range while preventing unintended Geiger mode operation, a crucial aspect that protects the integrity of the devices. The 767 Series also boasts low Noise Equivalent Power (NEP), high coupling efficiency exceeding 90%, and low Optical Return Loss (ORL), making it a versatile choice for a wide range of applications. CMC Electronics is well-positioned to meet diverse customer needs by offering standard Commercial Off-The-Shelf (COTS) components alongside customized co-design solutions.
In addition to the launch of the 767 Series, CMC Electronics continues to strengthen its presence in the optical technology sector, aligning its product offerings with emerging market demands. The company's commitment to innovation and quality positions it as a leader in providing advanced solutions that cater to the evolving requirements of the defense and communication industries.
With the introduction of the 767 Series, CMC Electronics reaffirms its dedication to delivering high-performance devices that enhance operational capabilities for its clients. As industries increasingly rely on precise optical measurements, CMC's new APD family stands poised to play a pivotal role in the advancement of detection and communication technologies. Further details and specifications for the 767 Series can be found on the company's website, showcasing their readiness to support both standard and customized solutions for various applications.
