CBO QSFP 49Y7891-LE-BL 3 m Male/Male 40 Gbit/s multimode fiber cable

This CBO QSFP 3 m Male/Male 40 Gbit/s multimode fiber cable by BlueOptics provides a pre-terminated, short-reach connection for QSFP ports. The cable is designed for high-speed multimode links and supports 40 Gbit/s data transfer over a 3 meter length. It is intended for use in data center and enterprise network environments where QSFP-compatible switches, servers and transceivers require a reliable direct fiber connection with minimal installation effort.

Advantages

The pre-terminated Male-to-Male fiber assembly reduces installation time and the risk of connector contamination compared with field-terminated solutions. Multimode construction supports high aggregate throughput at short distances while maintaining signal integrity for 40 Gbit/s links. The 3 m length balances flexibility and manageability in rack and cabinet deployments, and the QSFP-compatible terminations ensure plug-and-play interoperability with compatible hardware.

Suitable for

• Short-reach interconnects between QSFP ports in data centers
• Direct connections between switches, servers and transceivers
• High-density rack and cabinet fiber patches where 3 m cabling is required
• Temporary or permanent links for 40 Gbit/s multimode networks

Key specifications

• Connector type: QSFP-compatible male to male multimode fiber
• Data rate: 40 Gbit/s
• Length: 3 meters
• Fiber type: Multimode
• Cable termination: Pre-terminated plug-and-play ends

How to use

Inspect the connectors for visible contamination or damage before insertion. Align each male QSFP termination with the corresponding QSFP port and insert gently until the connector seats fully. Ensure devices on both ends are powered down or in a safe state during installation if recommended by the equipment manufacturer. After installation, verify link status and throughput using network monitoring tools or device LEDs to confirm a stable 40 Gbit/s connection.

Recommendations

For best performance, route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius. Keep connector end-faces clean using approved fiber cleaning tools and protect unused ends with dust caps. Use this multimode cable for short-reach links; for longer distances or single-mode requirements select an appropriate fiber type and length.
