Transceiver CBO QSFP28 100G SR4 BO28L859S1D — 100 Gigabit SR4 multimode glasvezel

The Transceiver CBO QSFP28 100G SR4 BO28L859S1D is a QSFP28 form-factor optical module that delivers 100 Gigabit Ethernet connectivity over multimode fiber. It is engineered for short-range SR4 transmission, providing four parallel lanes of 25 Gbps each to support high-bandwidth links in data centers and enterprise networks. The module is designed for direct insertion into QSFP28-compatible ports, offering compact 100G links with plug-and-play operation and broad interoperability with switches and routers that accept QSFP28 SR4 optics.

Advantages

This QSFP28 100G SR4 transceiver offers a compact, industry-standard form factor for dense port deployments, enabling high-throughput connections while conserving rack space. The multimode SR4 design supports short-reach links with low power consumption compared to long-range optics, and the four-lane architecture provides reliable parallel transmission for 100G applications. The module's compatibility with common QSFP28 ports simplifies upgrades to 100G networks and reduces integration effort.

Suitable for

• Top-of-rack and end-of-row data center uplinks requiring 100 Gigabit capacity
• High-performance server and switch interconnects over multimode fiber
• Enterprise backbone links and aggregation in campus networks
• Short-range parallel fiber connections in switched fabric environments

Key specifications

• Form factor: QSFP28
