Transceiver CBO QSFP28-100G-SR4 100G fiber optic module

The Transceiver CBO QSFP28-100G-SR4 100G fiber optic module is a compact, hot-pluggable QSFP28 transceiver engineered for short-range multimode fiber links. It delivers 100 Gbps aggregate bandwidth using an SR4 optical interface and is intended for high-density data center applications, server uplinks and high-speed switching environments. The module supports straightforward integration with compatible QSFP28 ports to enable bandwidth expansion and network upgrades with minimal disruption.

Advantages

The module offers a high-density form factor that conserves rack space while enabling 100G connectivity. Its hot-pluggable design permits installation or replacement without powering down equipment. Built for short-reach multimode fiber, the transceiver provides predictable optical performance for data center interconnects and server-to-switch links. Compatibility with industry-standard QSFP28 interfaces facilitates interoperability across compatible switching and routing platforms.

Suitable for

• Data center spine-leaf and rack-to-rack links over multimode fiber
• Server uplinks to top-of-rack and aggregation switches
• High-speed switching fabrics and interconnects requiring 100 Gbps bandwidth
• Short-range multimode fiber runs in enterprise and colocation environments

Key specifications

• Form factor: QSFP28 (compact, four-lane electrical/optical interface)
• Data rate: 100 Gbps aggregate
• Optical interface: SR4 for short-range multimode fiber
• Fiber type: Multimode fiber (MMF)
• Installation: Hot-pluggable module for in-service insertion and removal

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port following the host equipment manufacturer’s guidance, ensuring proper orientation and a secure latch. Use appropriate multimode fiber patch cords and follow recommended cable routes to minimize bend radius and loss. Verify link status through the host device management interface and monitor optical parameters as provided by the platform to confirm correct operation.

Recommendations

For reliable short-range links, use high-quality OM3/OM4 multimode fiber and maintain recommended connector cleanliness. Avoid sharp bends and excessive cable tension. During upgrades, confirm platform compatibility and firmware support for QSFP28 SR4 modules to ensure full interoperability and performance.
