Australian supplier QSFP optical module 400G

FS, Smartoptics, Cisco, and GenOptics provide 400G QSFP-DD optical modules compatible with Australian networks.FS (Fiberstore)FS offers 400GBASE-DR4 QSFP-DD modules compatible with Arista QDD-400G-DR4, supporting 8x50G PAM4 at 1310nm with a maximum reach of 500 meters over single-mode fiber. These modules are compliant with QSFP-DD MSA, IEEE 802.3bs, and 400GAUI-8 standards, and can be used as a 4x100G breakout solution. FS modules are fully certified for international safety and quality standards, including RoHS and REACH compliance, and are available for purchase in Australia through FS's regional distribution channels .SmartopticsSmartoptics provides QSFP-DD transceivers for 400G and 800G networks, optimized for both short-range multimode and coherent DWDM applications. Their modules support 2x100G connections over single-mode fiber, OTN compliance, Open ROADM interoperability, and AES-256 encryption for Layer 1 security. Smartoptics modules are suitable for metro, regional, and data center interconnect (DCI) networks, and can be sourced in Australia through authorized distributors .CiscoCisco's 400G QSFP-DD Ultra Long-Haul Coherent Optics Modules enable 400G traffic over dense wavelength division multiplexing (DWDM) networks. These modules support C-band and L-band coherent transmission, OpenROADM 7.0 compliance, and backward-compatible 400G QSFP-DD ZR+ modes. Cisco modules are globally distributed, including in Australia, and are ideal for regional and ultra-long-haul optical networks .GenOpticsGenOptics offers the MQD-36F2C 400G QSFP-DD transceiver, designed for 2km optical communication applications. It supports 425Gbps over four parallel lanes, QSFP-DD MSA compliance, and 400GAUI-8 standards. The module is engineered for harsh operating conditions, including temperature, humidity, and EMI interference, making it suitable for high-performance data center deployments .SummaryWhile there is no widely recognized Australian-based manufacturer of 400G QSFP-DD modules, several international vendors such as FS, Smartoptics, Cisco, and GenOptics provide modules that are available in Australia through regional distributors. These modules cover a range of applications from short-reach data center interconnects to ultra-long-haul DWDM networks, offering flexibility in deployment, high-speed performance, and compliance with international standards.
