About the JNP-QSFP-100G-LR4

The Juniper JNP-QSFP-100G-LR4 optical transceiver delivers high performance 100 Gigabit Ethernet connectivity for long-reach data center interconnects and metropolitan campus backbones. It multiplexes four LAN-WDM optical wavelengths around 1310 nanometers over standard duplex single mode fibre, delivering full rate 100Gbps transport up to 10 kilometers.

Compatibility

Compatible with Juniper QFX5120, QFX5200, QFX5210, QFX5220, QFX10000 Series switches, and MX Series modular routers. It integrates natively into QSFP28 switch interfaces and provides real-time telemetry diagnostics via Junos OS command line and telemetry collectors.

How to identify a genuine unit

Enclosed in a precision QSFP28 metal casing with a blue pull tab extraction mechanism indicating longwave single mode optics. The manufacturer label identifies part designation JNP-QSFP-100G-LR4, assembly part number 740-058735, and international safety compliance marks.

Buying used

Inspect the duplex LC optical receptacle with an optical inspection scope to ensure lack of contamination. Mount into a live Junos switch port to confirm that all four internal DFB laser channels lock into frequency and show balanced optical output power.

Works together

How the Juniper JNP-QSFP-100G-LR4 connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Storage

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.
