Fiber optic transceiver CBO Q28-100G-SR4 100G multimode SR4

CBO Q28-100G-SR4 100G multimode SR4 is a fiber optic transceiver module designed for short-reach, high-bandwidth links. Built for QSFP28 ports, this 100G multimode SR4 transceiver enables aggregation and server interconnects in data centers and enterprise networks. It supports transmission over multimode fiber for typical short-distance applications where high throughput and low-latency connectivity are required.

Advantages

The transceiver provides 100 gigabit capacity in a compact QSFP28 form factor, allowing network upgrades without changing switch port architectures. Its multimode SR4 design reduces cabling complexity for short-reach links and supports high-density deployments. The module is compatible with standard QSFP28 interfaces and is intended to deliver stable optical performance for aggregation, top-of-rack and server-to-server connections.

Suitable for

• Data center aggregation and spine-leaf links
• Top-of-rack (ToR) switch uplinks
• High-bandwidth server interconnects
• Short-reach multimode fiber connections within campus or enterprise environments

Key specifications

• Form factor: QSFP28
• Nominal data rate: 100 Gbit/s
• Optical type: Multimode SR4
• Typical application: Short-reach links over multimode fiber
• Compatibility: Designed for QSFP28 fiber interfaces in switches and routers

How to use

Install the transceiver into a compatible QSFP28 port on the switch or router until it clicks securely. Connect appropriate multimode fiber cables and verify link status in the device management interface. Ensure transmit and receive channels are correctly routed and that transceiver settings match the host device configuration. Monitor optical metrics and link performance after installation to confirm stable operation.

Recommendations

Use high-quality multimode fiber and compliant MPO/MTP cabling for SR4 links and follow manufacturer guidelines for connector cleanliness and handling to maintain optical performance and reduce signal loss.
