Transceiver CBO QSFP28-100G-SR4 compatible BO28L859S1D Fiber Optic 100G, multimode short-reach

Compatible CBO QSFP28-100G-SR4 transceiver (model BO28L859S1D) is a fiber-optic 100G short-reach module designed for multimode links. The module delivers four parallel 25G optical lanes in a compact QSFP28 form factor, providing a hot-pluggable solution for high-density environments. It is intended for use in data centers, enterprise switches and aggregation equipment where short-distance multimode fiber cabling is deployed.

Advantages

This QSFP28 100G SR4 transceiver supports standardized 100 Gigabit SR4 operation over multimode fiber, enabling interoperability with compatible switching and routing hardware. Its QSFP28 form factor and hot-pluggable design simplify installation and replacement without powering down systems. The module offers a balance of high port density, multimode short-reach performance and predictable power characteristics suitable for rack-to-rack and server interconnect scenarios.

Suitable for

• Short-reach 100G multimode links in data centers
• Server-to-switch and switch-to-switch rack connectivity
• High-density aggregation and leaf-spine network architectures
• Environments using OM3/OM4 multimode fiber for distances typical of SR4 modules

Key specifications

• Form factor: QSFP28, 4-lane 25G optical interface
• Data rate: 100 Gbit/s aggregate
• Fiber type: multimode fiber compatibility
• Reach: short-reach multimode distances (designed for rack-to-rack and intra-site links)
• Installation: hot-pluggable

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port on switches, routers or network interface cards following the host equipment manufacturer’s guidelines. Connect the module to multimode fiber cabling using an appropriate MPO/MTP trunk or harness that matches the transceiver’s four-lane fiber interface. After physical installation, verify link status and performance via the host device management interface and ensure transceiver settings are accepted by the equipment.

Recommendations

For reliable operation, use multimode fiber of suitable grade (for example OM3 or OM4) and maintain proper cable management to avoid excessive bend radius or contamination of fiber endfaces. Confirm compatibility with the host system and test links after installation to ensure expected throughput and signal integrity.
