## Summary description

CBO QSFP28-100G-SR4 is a 100G fiber optic transceiver module designed for short-range multimode links. It fits QSFP28 ports and provides 100 Gigabit Ethernet connectivity over multimode fiber using SR4 optics. Suitable for data centers and high-speed network aggregation where short-distance, high-bandwidth connections are required.

## Long description

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.
Usage 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.
