Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G QSFP28 module for short-range multimode networks

The Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G QSFP28 module for short-range multimode networks is a hot-pluggable QSFP28-form-factor transceiver designed to support 100 Gigabit Ethernet links over multimode fiber. Intended for data center and aggregation layer use, the module implements 4-lane SR4 optical transmission to deliver high-bandwidth connectivity between switches, servers and optical patch panels in short-reach multimode environments.

Advantages

This QSFP28 SR4 transceiver provides compact 100G density in a standardized hot-pluggable form factor and is compatible with QSFP28 ports on switches and servers that accept SR4 optics. The 4-lane design enables parallel transmission over multimode fiber for low-latency, high-throughput links. Its plug-and-play nature simplifies deployment and replacement without requiring system downtime or special tools.

Suitable for

• Short-reach 100G links inside data center racks and between adjacent racks
• High-speed aggregation between leaf and spine switches
• Interconnects for servers, storage arrays and top-of-rack switches over multimode fiber
• Environments requiring hot-swappable, high-density 100G ports

Key specifications

• Form factor: QSFP28 hot-pluggable
• Data rate: 100 Gbit/s (4×25 Gbit/s lanes)
• Optical interface: SR4 parallel multimode fiber
• Typical reach: optimized for short-range multimode links (data center distances)
• Wavelengths: multimode VCSEL-based lanes
• Power supply: powered via QSFP28 host interface
• Operating environment: designed for standard data center temperature ranges

How to use

Insert the QSFP28 module into a compatible QSFP28 port on a switch, router or server until it seats firmly; the module is hot-pluggable so it can be installed or removed while the host is powered. Connect the multimode fiber cable assembly that matches SR4 parallel interfaces (appropriate MPO/MTP connectors) between devices. Verify link status through the host device management interface and, if required, configure port speed and lane mapping according to the network equipment documentation. Follow standard ESD precautions during handling.

Recommendations

Use multimode fiber of appropriate OM class and quality, and ensure MPO/MTP connectors and patch panels are clean to maintain link performance. Match the transceiver to host compatibility lists when available, observe manufacturer guidelines for operating temperature and power budget, and perform link testing after installation to confirm expected throughput and signal integrity.
