HPE 817040-B21

Compatible 40GBASE‑SR4 QSFP transceiver module – 850 nm, MPO, TAA Compliant

The 817040‑B21 40GBASE‑SR4 QSFP transceiver module (compatible) enables high-density 40 Gigabit Ethernetconnectivity over multimode fiber using standard MPO/MTP connections. Supporting link distances up to 150 m on OM4 and 100 m on OM3 fiber, this module delivers full-duplex 40 Gbps throughput via four independent 10.3125 Gbps lanes. It features Digital Optical Monitoring (DOM) for real‑time diagnostics and is TAA compliant—suitable for government and compliant enterprise environments.Engineered for use in HPE BladeSystem and Synergy interconnects, this plug-and-play module offers reliable, manufacturer‑tested performance for data centers, aggregation switches, and high-speed fiber uplinks. Its low-power design (<1.2 W) and MSA‑compliant QSFP+ interface ensure broad compatibility with enterprise networking gear.

Features

This transceiver supports 40GBASE‑SR4 Ethernet (IEEE 802.3ba) over multimode fiber at 850 nm wavelength, transmitting via MPO‑12 connectors. Each of the four transmit and receive channels runs at up to 10.3125 Gbps, yielding an aggregate 41.25 Gbps data rate. It operates over OM3 up to 100 m and OM4 up to 150 m, making it ideal for short-reach high-density optical uplinks in data center or campus fabric designs

Advanced Options

Built to meet MSA standards—including SFF‑8436, SFF‑8679, and SFF‑8636—this transceiver is hot-swappable and supports DOM/ DDM for monitoring real-time optical power, temperature, and voltage via I²C/TWI interfaces

Product Key Features

    • Supports 40GBASE‑SR4 over MMF (OM3/OM4)

    • Aggregate throughput up to 41.25 Gbps via four lanes

    • MPO‑12 interface with duplex QSFP+ form factor

    • Link distance: up to 100 m on OM3; 150 m on OM4

    • Built‑in Digital Optical Monitoring (DOM/ DDM) support

    • TAA-compliant, RoHS/CE/FCC/REACH certified

    • Power consumption under 1.2 W; ambient range 0–70 °C


Reliability & Performance

Designed for high-density fiber connectivity, this QSFP+ transceiver delivers reliable, low-latency optical links with minimal insertion loss. Integrated DOM allows real-time monitoring of parameters like optical output, temperature, and voltage—helpful for proactive diagnostics. The tested compatible modules are factory-calibrated and serialized to ensure OEM-level interoperability and initialization behaviorIts low power consumption (≤1.2 W) and support for extended operating temperatures make it well-suited for enterprise and data center environments. Compliance with multiple industry standards ensures broad vendor compatibility and long-term deployment reliability.
