100G DR QSFP28 LC transceiver HPE Aruba S3N88A 500m SMF

The HPE Aruba 100G DR QSFP28 LC Transceiver is a compact optical module designed for 100 Gigabit Ethernet links over single-mode fiber. Supporting a maximum data transfer rate of 100000 Mbit/s and a link reach of up to 500 meters, this transceiver provides high-bandwidth connectivity for data center and enterprise network uplinks. Its QSFP28 electrical interface and LC optical connectors allow integration into compatible switches and routers that accept QSFP28 DR modules.

Advantages

This transceiver offers a small form factor that conserves port density while delivering 100 Gb/s throughput. The single-mode fiber design enables reliable long-reach connections up to 500 meters, suitable for many intra-data-center and campus backbone links. Low weight and standardized QSFP28 interface simplify installation and replacement in HPE Aruba and other QSFP28-capable networking equipment.

Suitable for

• Data center uplinks and spine-to-leaf connections
• Campus backbone and aggregation links
• High-density switch ports requiring 100 Gb/s over single-mode fiber
• Short-reach optical runs within or between equipment rooms up to 500 m

Key specifications

• Interface type: QSFP28 electrical interface with LC duplex optical connector
• Maximum data transfer rate: 100000 Mbit/s (100 Gb/s)
• Optical fiber type: single-mode fiber (SMF)
• Maximum reach: up to 500 meters over SMF
• Form factor: QSFP28 optical transceiver
• Typical weight: 0.0635 kg

How to use

Install the transceiver into a QSFP28-compatible SFP port on a switch or router, ensuring the host device supports 100G DR modules. Connect LC-terminated single-mode fiber patch cords to the module’s LC ports, observing proper polarity and fiber handling practices. Verify the link status and negotiated speed on the host device after insertion. Remove the transceiver by disengaging any retention mechanism on the port and pulling the module straight out to avoid damage.

Recommendations

Use high-quality single-mode LC fiber patch cords and maintain clean connector endfaces to ensure optimal signal integrity. Confirm compatibility with your switch or router firmware and QSFP28 DR support before deployment. Avoid excessive bending of fiber cables and store spare transceivers in anti-static packaging.
