Transceptor de fibra óptica CBO QSFP-40G-SR4 40G multimodo QSFP+

The BlueOptics CBO QSFP-40G-SR4 is a 40G multimode fiber optic transceiver in a QSFP+ form factor designed for short-range Ethernet and data center interconnects. The module provides aggregated 40 Gbps bandwidth across four parallel lanes and supports hot-pluggable installation into compatible QSFP slots. It is intended for use in high-density network environments where compact, energy-efficient short-reach optical links are required.

Advantages

The transceiver supports aggregated 40 Gbps throughput while occupying a single QSFP+ port, enabling high-density deployment in switches and servers. Its multimode optics and short-reach design reduce cabling complexity and lower power consumption compared with multiple discrete SFP+ links. Hot-pluggable capability allows replacement or upgrades without powering down equipment. The module is compatible with standard MPO connector cabling widely used in data centers.

Suitable for

• Switch-to-switch links in data center racks
• Server uplinks and top-of-rack aggregation
• Storage area network (SAN) interconnects over multimode fiber
• Short-range campus or enterprise backbone connections

Key specifications

• Form factor: QSFP+ (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregated (4 x 10 Gbps lanes)
• Fiber type: Multimode fiber (MMF)
• Connector type: MPO/MTP compatible multi-fiber interface
• Operating range: Short-range multimode links (typically up to 100 m on OM3 and up to 150 m on OM4, subject to fiber type and channel conditions)
• Hot-pluggable: Yes
• Typical applications: Ethernet, data center interconnect, SAN

How to use

Insert the QSFP+ transceiver into an available QSFP port on a compatible switch, router or host adapter while the device is powered on; the hot-pluggable design permits installation without shutting down the system. Connect an MPO/MTP multimode patch cable between the module and the matching MPO-enabled harness or breakout assembly. Verify link status through the network device’s management interface and configure port speed and VLANs as required by your network design.

Recommendations

Choose multimode fiber of appropriate grade (OM3 or OM4) to meet desired reach and performance. Use MPO/MTP cabling and polarity-correct patching or breakouts for 40G links. Ensure QSFP+ slot firmware and device driver compatibility with the transceiver and perform link tests after installation to confirm optical power levels and signal integrity.
