Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.

Tested to factory specification. Backed by 25 years of enterprise trust.

The Juniper JNP-QSFP-100G-SR4 is a high-performance QSFP28 100GBase-SR4 optical transceiver designed for short-range, high-density 100 Gigabit Ethernet deployments. Whether you're scaling your data center, expanding your core network, or upgrading existing infrastructure, this module delivers the reliability and throughput that modern enterprise environments demand.
