Optický QSFP28 transceiver CBO F5-UPG-QSFP28-SR4 100G SR4

CBO F5-UPG-QSFP28-SR4 100G SR4 is a QSFP28 fiber optic transceiver designed for short-reach 100 Gigabit Ethernet links over multimode fiber. The module implements a 4-lane parallel optical interface (SR4) to deliver 100 Gbps aggregate bandwidth in a hot-pluggable QSFP28 form factor. It is intended for high-density data center and enterprise network environments where reliable, low-latency aggregation and spine-leaf connectivity are required.

Advantages

The transceiver supports a 100G data rate using a parallel SR4 multimode configuration, enabling cost-effective short-distance high-bandwidth links. Its QSFP28 hot-pluggable design allows easy installation and replacement without powering down equipment. Built to industry-standard electrical and optical specifications, the module provides interoperable connectivity with compatible switches, routers and line cards while maintaining signal integrity across multimode fiber.

Suitable for

• Short-reach 100 Gigabit Ethernet links in data centers
• Aggregation and spine-leaf network topologies
• High-density switch and server interconnects using multimode fiber
• Upgrades and hot-swap replacements in enterprise networks

Key specifications

• Form factor: QSFP28 hot-pluggable
• Data rate: 100 Gbps aggregate over 4 parallel lanes
• Optical mode: Multimode fiber (SR4 parallel optics)
• Typical reach: short-reach multimode distances (designed for data center links)
• Connector interface: MPO/MTP-compatible parallel optical connector
• Temperature range: designed for standard data center operating conditions

How to use

Install the QSFP28 transceiver into a compatible QSFP28 slot on a switch, router or server line card while the host equipment is powered according to the vendor’s hot-plug instructions. Connect the module to multimode fiber using an MPO/MTP-compatible harness or patch cable wired for SR4 parallel lanes. Verify link status and speed through the host device management interface and monitor optical diagnostics where supported to ensure correct operation.

Recommendations

Use OM3 or OM4 multimode fiber for reliable short-reach performance and follow structured cabling best practices. Ensure transceiver compatibility with the host device and verify lane mapping with MPO/MTP cabling. Handle the optical connector and module with dust caps installed until connection to prevent contamination and maintain signal quality.
