100G QSFP28 LR4 10km Single‑Mode Optical Transceiver | NodeOptic

The NodeOptic 100GBASE‑LR4 QSFP28 transceiver delivers reliable 100Gbps connectivity up to 10km over OS2 single‑mode fiber using duplex LC connectors. Designed for high‑performance leaf‑spine, data‑center interconnect and ISP aggregation networks, this module integrates four LAN‑WDM 25G channels around 1310nm with low power consumption and consistent latency. Fully compliant with QSFP28 MSA, IEEE 802.3ba 100GBASE‑LR4 and relevant ITU‑T standards, this 100G optical transceiver provides a cost‑effective alternative to OEM modules without sacrificing performance. It supports Digital Diagnostic Monitoring (DOM/DDM), allowing network engineers to track real‑time parameters such as transmit and receive optical power, module temperature, supply voltage and bias current for proactive link maintenance. Wide Compatibility This 100G QSFP28 LR4 module is coded to interoperate seamlessly with a wide range of mainstream 100G switches and routers. It functions identically to the following OEM part numbers (and more): Cisco: QSFP‑100G‑LR4 / QSFP‑100G‑LR4‑S Arista: QSFP‑100G‑LR4 Juniper: QSFP‑100GBASE‑LR4 HPE / Aruba: JL275A (or equivalent 100GBASE‑LR4 QSFP28)
