Network transceiver module CBO BlueOptics QSFP 4x SFP+ 40 Gbit/s, MPN 470-13419-BL

The CBO BlueOptics QSFP 4x SFP+ 40 Gbit/s transceiver module aggregates four independent SFP+ lanes into a single QSFP interface delivering up to 40 Gbit/s. The compact QSFP form factor is designed for high-density data center and enterprise networking environments and supports hot-plug installation to simplify upgrades and maintenance. This module is intended for use as a QSFP-to-4×SFP+ breakout or as a 40 Gbit/s uplink where compatible switches, servers and optical cabling infrastructures are available.

Advantages

This transceiver provides four SFP+ lanes consolidated into a single QSFP port, enabling flexible port aggregation and higher port density without requiring separate 40 Gbit/s optics. Hot-pluggable design reduces downtime during replacement or upgrades, and the standard QSFP footprint supports broad vendor compatibility in modular platforms. The compact module supports common data center topologies and allows migration paths from 10 Gbit/s to 40 Gbit/s links while preserving existing SFP+ cabling where breakout cables are used.

Suitable for

• Aggregating four 10 Gbit/s links into a single 40 Gbit/s uplink
• High-density switch uplinks in data centers and enterprise networks
• Server interconnects requiring consolidated bandwidth
• QSFP-to-4×SFP+ breakout configurations for campus and rack deployments

Key specifications

• Interface: QSFP single port with four independent SFP+ lanes
• Aggregate data rate: up to 40 Gbit/s
• Form factor: QSFP hot-pluggable module
• Application: breakout to four 10 Gbit/s links or native 40 Gbit/s connection
• Compatibility: designed for use with QSFP-capable switches and SFP+-equipped devices

How to use

Install the module into an available QSFP port on a compatible switch or network device following the device manufacturer’s hot-swap guidelines. If a breakout configuration is required, connect appropriate QSFP-to-4×SFP+ breakout cables to the module’s SFP+ lanes and attach them to the target SFP+ ports on other devices. Verify link status and speed through the switch or host management interface and ensure transceiver lane mapping matches the intended topology. Remove the module by following safe hot-unplug procedures to prevent link disruption.

Usage recommendations

Use this module with certified QSFP-to-4×SFP+ breakout cables and compatible transceiver ports to ensure expected performance. Verify optical or DAC cable types and reach before deployment, and consult switch vendor documentation for supported transceiver modules and firmware compatibility.
