Transceptor CBO QSFP28-100G-SR4 100G SR4 módulo transceptor de fibra óptica

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.

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.
