Product Highlights
1.40km Extended Long-Haul
- Delivers reliable 100Gbps data transmission up to 40km when Forward Error Correction (FEC) is enabled on the host, or up to 30km without FEC over standard G.652 single-mode fiber (SMF).
2.High-Efficiency LAN-WDM
- Utilizes four tightly spaced LAN-WDM wavelengths (1295.56nm to 1309.14nm) multiplexed over a standard Duplex LC connector, maximizing existing fiber core infrastructure.
3. Real-Time Telemetry (DOM)
- Integrated Digital Optical Monitoring via $I^2C$ interface provides live telemetry—including temperature, supply voltage, laser bias current, and TX/RX optical power—for proactive network management.
4.Carrier-Grade Reliability
- Operates within commercial temperature ranges (0℃to+70℃） with optimized low power consumption (<4.5W), meeting Class 1 laser safety (IEC 60825-1) and RoHS standards.
5.100% Cisco Interoperability
- Engineered to fully comply with QSFP28 MSA and IEEE 802.3ba 100GBASE-ER4L standards, ensuring seamless plug-and-play operation with zero error codes on Cisco Nexus, Catalyst, and ASR platforms.
