## Summary description

CBO QSFP28-100G-SR4 is a 100G SR4 fiber-optic transceiver module in QSFP28 form factor for short-reach multimode fiber links. Designed for 100 Gigabit Ethernet, it provides four lanes of 25Gb/s optical transmission using SR4 signaling. Suitable for data center interconnects, switch-to-switch links and high-speed aggregation where multimode short-reach connectivity is required.

## Long description

The Transceiver CBO QSFP28-100G-SR4 100G SR4 fiber optic module is a QSFP28-form-factor optical transceiver designed for short-reach multimode fiber links. It implements SR4 signaling to deliver 100 Gigabit Ethernet over four parallel lanes of 25 Gb/s each, enabling high-bandwidth connections between switches, servers and aggregation devices in data center and campus environments. The module supports multimode fiber standards typically used for short-range interconnects and fits into QSFP28 ports on compatible network equipment.
Advantages
This QSFP28 100G SR4 transceiver provides compact high-density 100 Gigabit Ethernet connectivity with four independent 25 Gb/s optical lanes, enabling efficient use of QSFP28 slots in modern switches and routers. The module is engineered for short-reach multimode fiber, offering predictable performance for intra-rack and inter-rack links. Its standard form factor and optical interface simplify installation and replacement in environments that require reliable, high-throughput fiber links.
Suitable for
Data center switch-to-switch connections over multimode fiber
High-speed aggregation links between network devices
Short-reach server uplinks within racks and between adjacent racks
Multimode fiber links in campus and enterprise networks
Key specifications
Form factor: QSFP28
Data rate: 100 Gb/s (4 × 25 Gb/s lanes)
Optical interface: SR4 multimode
Reach: short-reach multimode fiber links (multimode OM3/OM4 typical)
Wavelength: parallel multimode transmission using 4 lanes
Application: 100 Gigabit Ethernet
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port on the network device until it seats securely, following the device manufacturer's guidance on hot-plugging. Connect the transceiver to a compatible multimode MPO/MTP cable assembly that matches the SR4 lane mapping and multimode fiber grade. Verify link status and speed through the host device management interface and monitor signal quality and error counters to ensure stable operation.
Usage recommendations
Use certified OM3 or OM4 multimode fiber and compatible MPO/MTP cabling assemblies to achieve the expected short-reach performance. Confirm compatibility with the host device's QSFP28 port and firmware, and follow electrostatic discharge (ESD) handling procedures during installation and removal.
