Transceptor QSFP28 de fibra óptica CBO QSFP28-100G-SR4 100G SR4 Multimodo

CBO QSFP28-100G-SR4 is a fiber optic QSFP28 transceiver module that supports 100G SR4 multimode operation for short-reach 100 Gigabit Ethernet links. Designed for high-density data center and enterprise network environments, this compact, hot-pluggable module provides four parallel lanes of multimode fiber connectivity to enable server-to-switch and switch-to-switch interconnects. The module is compatible with QSFP28 ports and offers a small form factor suitable for modern rack and spine-leaf architectures.

Advantages

The transceiver delivers reliable short-reach 100G performance over multimode fiber with a compact QSFP28 form factor and hot-pluggable design that simplifies deployment and replacement without powering down equipment. It supports four parallel lanes to achieve aggregate 100G bandwidth while enabling high port density in switches and routers. The module's design minimizes space and power requirements compared with discrete optics solutions and is intended for seamless integration into existing multimode fiber infrastructures.

How to use

Install the QSFP28 module into a compatible QSFP28 port on a switch, router, or network adapter while the host device is powered according to the vendor's maintenance procedures. Connect the module to the multimode fiber trunk using an MPO/MTP cable with appropriate polarity and fiber type (OM3 or OM4 as recommended). Verify link status and performance via the host device management interface and monitor signal parameters where supported. Replace or re-seat the module as needed without powering down systems, following electrostatic discharge (ESD) precautions.

Recommendations

Use OM3 or OM4 multimode fiber for intended reach and performance; ensure correct MPO/MTP polarity and cleanliness of connectors to maintain signal quality. Confirm compatibility with the host equipment vendor and firmware to avoid interoperability issues. Follow standard ESD handling and data center cabling best practices during installation and maintenance.
