## Summary description

CBO QSFP28-100G-SR4 is a QSFP28-form-factor fiber optic transceiver supporting 100G links for short-range multimode applications. Designed for data center and high-speed aggregation use, it provides 4-lane SR4 transmission over multimode fiber, hot-pluggable QSFP28 compatibility, and straightforward integration into switches and servers to enable high-bandwidth connectivity.

## Long description

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.
Usage 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.
