100GBASE-SR4 Technology

The HPE 849443-001 uses the 100GBASE-SR4 architecture. Instead of carrying the entire 100Gbps signal over a single optical channel, the link uses four parallel optical lanes, each operating at 25Gbps.

HPE specifically describes the 849443-001 as a QSFP28 MPO module with four optical lanes in each direction, allowing each lane to operate at 25Gbps. :contentReference[oaicite:2]{index=2}

This parallel architecture is optimized for short-reach multimode-fiber connections commonly found inside modern data centers.

850nm Multimode Optical Technology

The transceiver operates at approximately 850nm and is designed for multimode fiber. This combination is widely used for short-distance 40G and 100G data-center optical networking.

The short-wavelength design makes the module particularly suitable for OM3 and OM4 structured multimode-fiber installations.

100m OM4 Reach

The HPE 849443-001 is specified for up to 100 meters of 100GBASE-SR4 connectivity. Distributor specifications identify OM4 multimode fiber for the 100m reach and OM3 compatibility for the SR4 application. :contentReference[oaicite:3]{index=3}

Actual link distance depends on fiber grade, modal bandwidth, connector insertion loss, patch-panel losses, polarity and the complete optical path.

MPO Connectivity

The HPE 849443-001 uses an MPO optical connector. The parallel SR4 architecture requires multiple optical fibers for the four transmit and four receive lanes.

Correct MPO polarity and lane mapping are essential when installing the transceiver. Compatible MPO/MTP multimode cabling should be used for the complete optical link.

Four 25Gbps Optical Lanes

The module provides four optical lanes in each direction. Each lane operates at 25Gbps, resulting in a 100Gbps aggregate Ethernet connection.

This parallel architecture allows a compact QSFP28 module to deliver very high bandwidth while using a single high-density MPO interface.

QSFP28 Form Factor

The HPE 849443-001 uses the compact QSFP28 form factor. QSFP28 was developed for high-density 100Gbps networking and provides four independent high-speed lanes within a compact pluggable module.

This makes the module suitable for high-port-density HPE switches and other compatible networking platforms.

Data Center Connectivity

The HPE 849443-001 is particularly suitable for short-distance data-center connections where 100Gbps bandwidth is required over multimode fiber.

Typical deployments include leaf-to-spine connections, switch uplinks, aggregation links and high-performance computing infrastructure.

100G SR4 vs 100G LR4

The HPE 849443-001 is intended for short-range multimode-fiber links. For 100G connections extending several kilometers, an appropriate single-mode 100G optic such as LR4 should be used instead.

Compatibility

The HPE 849443-001 is an HPE-specific transceiver and should be installed in compatible HPE networking equipment.

HPE documentation lists the 849443-001 across supported HPE networking platforms, including HPE Composable Fabric and Aruba networking documentation. :contentReference[oaicite:4]{index=4}

Before purchase, verify the exact switch, network adapter or platform model and its supported transceiver list. Vendor coding and firmware requirements can affect compatibility even when the optical specification is standardized.
