$162.00

SKU: 720187-B21-US Categories: , , OEM Equivalent: HP 720187-B21

The US Transceivers compatible 720187-B21 is a high-performance 40GBASE-SR4 QSFP+ transceiver designed as a fully compatible replacement for HP networking environments. Operating over OM3 and OM4 multimode fiber, this module delivers 40 Gbps aggregate throughput across four parallel 10 Gbps lanes using an 850 nm VCSEL array, supporting link distances up to 150 m on OM4 fiber.

Featuring an MPO/MTP connector interface, the module integrates seamlessly into high-density data center deployments and supports Digital Diagnostic Monitoring (DDM) for real-time visibility into optical performance parameters including temperature, voltage, TX power, and RX power. The hot-pluggable QSFP+ form factor ensures minimal disruption during installation or replacement.

This US Transceivers compatible module meets TAA compliance requirements and adheres to IEEE 802.3ba and QSFP+ MSA standards, making it a reliable, cost-effective alternative for 40G short-reach parallel optic applications in enterprise and data center networks.
