Juniper JNP‑QSFP‑100G‑LR4 100GBASE‑LR4 QSFP28 Optical Transceiver Module

The Juniper JNP‑QSFP‑100G‑LR4 Compatible QSFP28 Transceiver is a high‑performance 100GBASE‑LR4 QSFP28 transceiver designed for reliable 100 Gigabit Ethernet connectivity over single‑mode fiber (SMF) networks. It complies with the IEEE 802.3ba 100GBASE‑LR4 standard and QSFP28 MSA, delivering up to 100 Gbps aggregate throughput over a pair of SMF strands with duplex LC connectors. Typical supported reach is up to 10 km on standard SMF (G.652), making it ideal for long‑distance links between data centers, core aggregation, and campus backbone interconnects.

Operating at LAN‑WDM wavelengths (typically around 1295 nm to 1309 nm), this module uses four 25 Gbps optical lanes multiplexed into a single 100 Gbps channel, enabling robust high‑speed optical transport over long distances with low latency. The transceiver also supports Digital Optical Monitoring (DOM) for real‑time diagnostic access to link operating parameters (optical power, temperature, bias current), which helps with maintenance and troubleshooting. It’s hot‑pluggable and MSA‑compliant for broad interoperability with compatible QSFP28 slots across switches, routers, and optical platforms.

Key Features:
• 100GBASE‑LR4 QSFP28 optical transceiver module for 100 Gbps Ethernet over single‑mode fiber.
• Duplex LC interfaces for standard SMF cabling.
• Typical reach up to 10 km (up to 20 km variants available).
• IEEE 802.3ba 100GBASE‑LR4 and QSFP28 MSA compliant.
• Digital Optical Monitoring (DOM) support for real‑time diagnostics.
• Hot‑pluggable QSFP28 form factor for easy installation and serviceability.
