Product Highlights

1.ADVA Certified for Data Center-Grade Reliability
Officially certified by ADVA and subjected to rigorous testing for data center reliability. It operates stably in high-density leaf-spine environments, ensuring seamless compatibility with ADVA platforms without interoperability or compatibility errors.
2.100G SR4 Short-Reach Multi-Mode Transmission
Built to the 100GBASE-SR4 standard, utilizing four parallel 850 nm optical lanes (4x25Gbps). It delivers reliable 100Gbps transmission up to 70 meters over OM3 multi-mode fiber and up to 100 meters over OM4/OM5 MMF, perfectly suited for intra-datacenter links.
3.MPO-12 Connector for High-Density Parallel Cabling
Features a standard MPO-12 interface, optimized for structured cabling in modern data centers. By leveraging parallel optics over MPO/MTP patch cords, it simplifies fiber management, reduces cable congestion, and lowers overall infrastructure costs in leaf-spine architectures.
4.Carrier-Class Thermal Optimization for Continuous Operation
Manufactured with premium VCSEL laser arrays and optimized for low power consumption (typically <2.5W). It offers excellent heat dissipation and long-term stability, fully meeting the strict continuous-operation and energy-efficiency requirements of high-density equipment rooms.
5.Comprehensive DDM/DOM Monitoring for Intelligent O&M
Integrated complete DDM/DOM digital diagnostic functions to monitor aggregate and per-channel Tx/Rx optical power, module temperature, voltage, and laser bias current in real time. This enables early fault prediction and proactive maintenance to prevent unexpected network outages.
6.Optimized QSFP28 Form Factor for High-Density Core Switches
Utilizes the compact and hot-pluggable QSFP28 form factor, ideal for high-density ADVA switches, routers, and transport line cards. It enables flexible, high-speed 100G port provisioning without sacrificing valuable rack space, supporting scalable network expansion.
