Product Highlights

• This transceiver fully complies with the IEEE 802.3bm 100GBASE-SR4 standard, delivering stable 100Gbps wire-speed transmission over multi-mode fiber (MMF).
• It operates at a wavelength of 850nm and uses a 4×25G parallel optical architecture, supporting up to 100m over OM4 fiber and up to 70m over OM3 fiber.
• The parallel optical interface is designed for high-density data center leaf-spine connections, using MPO-12 connectors to simplify multi-fiber ribbon cabling.

2. Standard QSFP28 Package & Broad Compatibility

• It uses the industry-standard QSFP28 (Quad Small Form-factor Pluggable 28) package, which is compact, hot-swappable, and designed for high port density in 100G switches and adapters.
• The module is natively compatible with Intel Ethernet adapters (e.g., XXV710, XL710) and switches, and works with most third-party devices supporting standard QSFP28 transceivers.
• Hot-plug-and-play design allows for easy installation, replacement, and capacity expansion without disrupting network operations.

3. Reliable Performance & Compliance Certification

• Built-in Digital Optical Monitoring (DOM) allows real-time monitoring of key parameters including TX optical power, RX optical power, module temperature, supply voltage, and laser bias current.
• Certified as a Class 1 Laser product under IEC 60825-1 and 21CFR(J), and compliant with RoHS standards, meeting global commercial and data center deployment requirements.
