About the JNP-QSFP-100G-CWDM4

The Juniper JNP-QSFP-100G-CWDM4 optical transceiver is designed for cost-effective intermediate distance 100 Gigabit Ethernet connectivity in large hyperscale and enterprise data centers. Operating across four CWDM optical wavelength lanes over duplex single mode optical fibre, it provides reliable links up to 2 kilometers between data center halls.

Compatibility

Compatible with Juniper QFX5120, QFX5200, QFX5210, QFX5220 switches, and MX Series routing platforms. It operates with host Forward Error Correction (RS-FEC) enabled on QSFP28 interfaces to ensure signal integrity across the full 2 kilometer optical reach in data center fabrics.

How to identify a genuine unit

Packaged in an industry standard QSFP28 metallic case featuring a green pull tab release mechanism denoting CWDM4 optical technology. The factory label states part number JNP-QSFP-100G-CWDM4, manufacturing assembly code 740-061405, and serial tracking number.

Buying used

Inspect the duplex optical port with a fiber scope to ensure no dust or surface scratching on the lenses. Plug the optic into a Junos OS switch port to verify that the transceiver authenticates cleanly and reports balanced optical power metrics across all four wavelength channels.

Works together

How the Juniper JNP-QSFP-100G-CWDM4 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.
