Product information

Description

The StarTech 3CSFP91ST is a Gigabit SFP fiber transceiver module compatible with HPE 3CSFP91. It provides 1 GbE connectivity (1000BASE-SX) over multi-mode fiber with LC connectors and supports link distances up to 550 m (1804 ft). The module features low power consumption (under 1 W), an aluminum housing, and a high MTBF, making it suitable for reliable network installations. Digital Diagnostics Monitoring (DDM) is supported and the module is hot-swappable to minimize network downtime.

Advantages

The transceiver offers dependable 1 GbE performance over multi-mode fiber with up to 550 m reach, low power usage, and DDM support for real-time diagnostics. Its hot-swappable SFP form factor simplifies upgrades and replacements, and the compact aluminum housing contributes to durability. The product is backed by StarTech.com’s lifetime warranty and lifetime multilingual technical support.

Suitable for

Connecting switches and routers over multi-mode fiber in LAN environments
Upgrading or replacing SFP ports in HPE-compatible equipment
Data center interconnects and campus backbone links within 550 m

Key specifications

Standard: 1000BASE-SX (1 GbE)
Maximum data transfer rate: 1.25 Gbps (1250 Mbit/s)
Fiber type: Multi-mode fiber (MMF)
Wavelength: 850 nm
Connector: LC
Maximum distance: 550 m (1804 ft)
Power consumption: < 1 W
MTBF: 3,381,761 hours
Interface type: SFP
Product colour: Silver

How to use

Ensure the host device (switch or router) supports SFP modules and is HPE-compatible if required. With the device powered on or per vendor guidance, insert the SFP transceiver into an empty SFP port until it clicks into place. Connect multi-mode fiber with LC connectors and verify link lights and DDM readings via the host management interface. To remove, depress the latch and pull the module straight out. Follow standard ESD precautions when handling the module and fiber connectors.

Usage recommendations

Use OM1/OM2/OM3/OM4 multi-mode fiber appropriate for the required link budget and keep fiber ends clean to ensure optimal performance. Verify compatibility lists for HPE devices if strict vendor validation is required, and keep a spare hot-swappable module on hand to reduce downtime during maintenance.
