This QSFP28 100GBASE-SR4 transceiver is designed for high-speed data transmission over multimode fiber optic networks. It operates at 850nm wavelength and supports distances up to 100 meters on OM4 multimode fiber, making it suitable for short-reach interconnects within data centers and enterprise networks. The module features an MPO connector and integrated Digital Diagnostic Monitoring (DDM) for real-time performance tracking. Built with robust housing and precision optics, it ensures stable signal integrity even under heavy traffic loads. Compatibility spans across major networking equipment from Cisco, Arista, Juniper, Nokia, and other standard MSA-compliant switches and routers. The transceiver delivers consistent 100G throughput with low power consumption, typically under 2.5W, and operates reliably across a wide temperature range. Its compact design allows for high port density without compromising airflow or heat dissipation. Each unit undergoes rigorous testing to meet industry specifications for optical output power, receiver sensitivity, and eye pattern performance. The cost-effective nature of this module makes it an attractive option for scaling network capacity without exceeding budget constraints. While not claiming absolute perfection, the transceiver offers a practical blend of performance, durability, and value for 100G SR4 applications. Users can expect straightforward installation with hot-pluggable capability and standard compatibility across most major brands. The module’s construction emphasizes long-term reliability with quality materials and solder joints. For network administrators seeking to upgrade legacy 10G/40G links to 100G, this transceiver provides a seamless migration path. Its 850nm VCSEL technology ensures efficient conversion of electrical signals to optical, maintaining low bit error rates even in dense cabling environments. The inclusion of DDM allows monitoring of temperature, voltage, laser bias current, and optical power levels, aiding in proactive maintenance.

This QSFP28 module represents a balanced solution for high-bandwidth optical connectivity.
