Manufacturer provides QSFP active optical modules

Leading manufacturers of QSFP active optical modules include Cisco, WolonFiber, FS, Unitekfiber, and Amphenol, offering 40G, 100G, 200G, and 400G solutions for data centers and enterprise networks.CiscoCisco provides a wide range of 100G QSFP modules, including SR4, SL4, and Bi-Directional (BiDi) transceivers. These modules are hot-swappable, IEEE-compliant, and tested for high performance and reliability. Cisco QSFP modules support multimode fiber links up to 150 meters and can be used for 400G breakout applications. They are compatible with Cisco QSFP ports and other IEEE-compliant 100GBASE interfaces, making them suitable for high-bandwidth Ethernet deployments in enterprise and data center environments .WolonFiberWolonFiber manufactures MSA-compliant 100G QSFP28, 200G QSFP56, QSFP-DD, and CFP2 optical modules. Their products are optimized for ultra-dense Spine-Leaf topologies and long-haul transport. WolonFiber modules leverage PAM4 modulation and low-power DSP technology, ensuring carrier-grade performance. They offer OEM and ODM services, including factory direct customization, thermal stress testing, and live verification for seamless integration with Cisco, Arista, Mellanox (NVIDIA), Juniper, and white-box switches .FS (Fiberstore)FS offers 40G QSFP+ transceiver modules with reach ranging from 150 meters to 80 kilometers. These modules are designed for high-density switching, routing, and data center applications, providing flexibility for both short-reach and long-reach optical links .UnitekfiberUnitekfiber is a global optical transceiver wholesaler providing a comprehensive portfolio of MSA-compliant transceivers, including 10G SFP+, 40G QSFP+, 100G QSFP28, 200G QSFP-DD/QSFP56, and 400G QSFP-DD modules. Their modules are engineered for low latency, high reliability, and full compatibility with major OEM hardware, making them suitable for AI clusters, hyperscale computing, and enterprise data centers .AmphenolAmphenol supplies 40G QSFP+ active optical cables (AOCs) and modules, including SR4, eSR4, IR4, LR4, ER4 lite, and AOC breakout series. These modules feature LC or MPO optical ports, low power consumption, compact size, and high-speed performance. They are widely used in large data centers, campus networks, and metropolitan area networks .SummaryThese manufacturers provide a range of QSFP active optical modules suitable for different network speeds and topologies. Cisco and WolonFiber focus on high-performance 100G and 200G modules with OEM customization, FS and Amphenol offer 40G solutions, and Unitekfiber covers a broad spectrum from 10G to 400G. When selecting a supplier, consider MSA compliance, compatibility with existing hardware, thermal management, and support for high-density deployments.
