Fiber Optic Transceiver CBO QSFP28-100G-SR4 100G SR4 multimode

The Fiber Optic Transceiver CBO QSFP28-100G-SR4 100G SR4 multimode is a QSFP28 form-factor module engineered for short-reach 100 Gigabit Ethernet links over multimode fiber. Designed for data center environments, the module supports SR4 specification and MPO/MTP connector interfaces to deliver high-throughput, low-latency connectivity between switches, racks, and aggregation points. It is built for plug-and-play deployment in systems that accept QSFP28 SR4 optics and interoperates with multimode fiber infrastructure commonly used for top-of-rack and spine-to-leaf interconnects.

Advantages

The module provides 100 Gbps aggregate bandwidth in a compact QSFP28 package, enabling dense port counts and efficient use of switch chassis space. SR4 multimode optics reduce link costs for short distances by using multimode fiber and MPO/MTP connectivity. The transceiver supports hot-plug operation for minimal disruption during installation or replacement and complies with established SR4 optical parameters to ensure predictable performance and interoperability with compatible equipment.

Suitable for

• Short-reach data center links between top-of-rack and aggregation switches
• Spine-to-leaf and switch-to-switch interconnects within a rack or across adjacent racks
• High-bandwidth, low-latency server clusters and virtualization backbones
• Environments using multimode fiber and MPO/MTP trunk cabling

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gigabit Ethernet aggregate
• Optical specification: SR4 for short-reach multimode fiber
• Connector type: MPO/MTP
• Fiber type: Multimode fiber (MMF)
• Hot-pluggable operation
• Typical application: Data center interconnect and aggregation

How to use

Install the transceiver into a compatible QSFP28 port on a switch or optical line card while the host supports SR4 optics. Ensure the MPO/MTP multimode fiber trunk is properly terminated and tested for insertion loss and polarity before mating. Insert the module until it seats and the host recognizes the optics; verify link status and diagnostics through the host management interface. When removing the module, use the appropriate release mechanism to avoid damaging the port or module.

Recommendations

For reliable performance, use multimode fiber of the recommended classification (OM3/OM4 as applicable), maintain proper fiber cleaning practices for MPO/MTP connectors, and confirm host compatibility with QSFP28 SR4 optics. Keep link distances within the SR4 short-reach range and monitor optical diagnostics to detect any degradation.
