Maintain high-speed connectivity across extended distances with this HP/Aruba compatible 40GBASE-ZR4 QSFP+ transceiver. Designed for 40 Gigabit Ethernet over single-mode fiber, it uses 1295/1300/1304/1309 nm wavelengths to support long-reach transport up to 80 km. That makes it well suited for campus interconnects, metro aggregation, and remote facility links where shorter optics fall short. Digital Optical Monitoring adds visibility into operating conditions, helping teams track transceiver health and plan maintenance before a link becomes a problem. The duplex LC interface keeps deployment straightforward in standard SMF environments, while the QSFP+ form factor fits common high-density switching platforms. As a compatible module, it gives infrastructure teams a cost-conscious path to extend existing HP/Aruba networks without changing the optical design of the link. For environments where uptime, distance, and predictable optics performance matter, this module delivers the reach and diagnostics needed to support critical 40 GbE transport.
