Transceiver CBO QSFP28-100G-SR4 100G fiber optic module for short-range multimode links

The Transceiver CBO QSFP28-100G-SR4 100G fiber optic module for short-range multimode links is a 100 Gigabit Ethernet QSFP28 transceiver designed for short-distance multimode fiber connections. Intended for QSFP28 ports, this module implements SR4 optics to deliver high-bandwidth links over parallel multimode fiber, providing a compact solution for server-to-switch, switch-to-switch and within-rack interconnects in data center environments and network aggregation points.

Advantages

This QSFP28 SR4 transceiver offers a small form factor with high port density and low power consumption relative to multiple-lane copper solutions. It supports 100G data rates over multimode fiber at short distances, enabling efficient use of existing MPO/MTP fiber infrastructure. The module's compatibility with QSFP28 interfaces simplifies upgrades to higher-speed links while preserving rack space and reducing cabling complexity.

Suitable for

• Data center short-reach interconnects (rack-to-rack, within-rack)
• High-density aggregation switches and spine-leaf architectures
• Server uplinks requiring 100 Gigabit Ethernet over multimode fiber
• Environments using MPO/MTP parallel multimode cabling

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gigabit Ethernet
• Optical type: SR4 multimode fiber optics
• Connector interface: MPO/MTP parallel fiber
• Link reach: short-range multimode distances (designed for within-rack and short inter-rack links)
• Application: parallel 4-lane multimode transmission

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch or network device, ensuring the module is oriented correctly and fully seated. Connect the MPO/MTP multimode fiber cable to the module's connector, observing correct polarity and fiber type. After physical installation, verify link status and configure the network interface on the host device as required. Monitor module status via the device management interface and perform routine checks on fiber cleanliness and connector integrity to maintain optimal performance.

Recommendations

Use this module with OM3 or OM4 multimode fiber to achieve expected short-range performance and follow MPO/MTP cabling best practices. Clean fiber connectors before mating, verify link parameters after installation, and ensure the host equipment supports QSFP28 SR4 optics for full interoperability.
