Transceptor CBO QSFP28-100G-SR4 fibra ótica 100G, QSFP28 SR4 multimodo 100G Short-Reach

The Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G is a QSFP28 multimode short-reach module designed to deliver 100 Gigabit/s links over parallel multimode fiber using SR4 topology. It fits into standard QSFP28 ports and provides hot-pluggable operation for straightforward installation and replacement in data center and enterprise networking equipment. The module is intended for high-density 100G connectivity where short-distance aggregation and server-to-switch or switch-to-switch links are required.

Advantages

This QSFP28 SR4 transceiver offers compact form factor and high port density to maximize rack-level bandwidth. The hot-pluggable design enables tool-free replacement and reduces downtime during maintenance. Compatibility with multimode SR4 topology ensures predictable short-reach performance in typical data center fiber infrastructures. The module is optimized for low-latency, high-throughput links and supports straightforward integration into existing QSFP28-capable switches and servers.

Suitable for

• Short-reach 100G links in data center top-of-rack and spine aggregation
• Server-to-switch high-bandwidth connections
• Switch-to-switch uplinks and chassis interconnects within the same facility
• Multimode fiber installations using SR4 parallel MPO connections

Key specifications

• Form factor: QSFP28 (quad small form-factor pluggable 28)
• Data rate: 100 Gigabit/s aggregate
• Optical topology: SR4 parallel multimode
• Fiber type: Multimode fiber (MMF)
• Reach: short-reach links over multimode fiber (typical distances determined by fiber grade and channel conditions)
• Connector interface: MPO parallel interface compatible with SR4 transceiver layouts
• Installation: hot-pluggable into QSFP28 ports

How to use

Install the transceiver into an empty QSFP28 port on a compatible switch, router, or network adapter until it seats firmly. Connect MPO multimode fiber patch cords matching SR4 pinout between paired transceivers or between device and breakout assemblies. Verify link status using device LEDs or management interface and ensure transceiver and equipment support the same 100G SR4 settings. For removal, power down or follow hot-swap procedures recommended by the equipment vendor and extract the module by pulling the release tab while protecting fiber connectors with dust caps when not in use.

Recommendations

Use OM3 or OM4 multimode fiber for optimal short-reach performance, keep patch cords and MPO connectors clean to avoid signal loss, and follow the host equipment vendor’s compatibility list for QSFP28 modules to ensure reliable operation.
