Transceptor de fibra ótica CBO QSFP28 BO28L859S1D 100G SR4 para ligações multimodo de curta distância

The Fiber optic transceiver CBO QSFP28 BO28L859S1D 100G SR4 for short-reach multimode links is a QSFP28-form factor optical module designed to deliver quad-lane 100 Gigabit Ethernet over multimode fiber. Intended for short-reach SR4 connections, the transceiver provides four parallel lanes aggregated to support 100G links in data center environments, switch-to-switch interconnects and high-speed server uplinks. The module supports hot-pluggable installation and conforms to standard QSFP28 mechanical and electrical interfaces for compatibility with a wide range of networking equipment.

Advantages

This 100G SR4 transceiver offers compact QSFP28 packaging that reduces port density and rack space compared with older form factors. Its design enables straightforward integration into existing multimode fiber infrastructures and minimizes downtime through hot-pluggable operation. Built for short-reach multimode links, the module balances cost and performance for typical intra-rack and adjacent-rack connections and supports industry-standard signaling for predictable interoperability.

Suitable for

• Data center top-of-rack and spine switch interconnects over multimode fiber
• Switch-to-switch links within a single facility or campus
• High-speed server uplinks and aggregation ports
• Short-reach multimode fiber infrastructure (OM3/OM4)

Key specifications

• Optical interface: SR4 multimode parallel optics
• Data rate: 100 Gigabit Ethernet (aggregated over four lanes)
• Form factor: QSFP28 hot-pluggable module
• Reach: short-range multimode links (designed for OM3/OM4 fibers)
• Connector type: MPO/MTP parallel fiber connector
• Operating environment: typical data center temperature and humidity ranges

How to use

Install the module into a compatible QSFP28 host port while the host device is powered on or off, following the host vendor’s guidance for hot-plug procedures. Connect the MPO/MTP multimode fiber cable to the module’s connector, ensuring correct polarity and using appropriate OM3 or OM4 patch cords for short-reach SR4 links. Verify link status and speed through the switch or server management interface and monitor optical signal parameters where available to confirm proper operation.

Recommendations

Use within data center environments with certified OM3 or OM4 multimode fiber for optimal performance; avoid single-mode fiber or unsupported cable types. Maintain clean connector end-faces, follow ESD precautions when handling the transceiver, and consult the equipment vendor’s compatibility list to ensure full interoperability.
