Transceptor CBO QSFP28 100G LR4 LC-Duplex

The Transceiver CBO QSFP28 100G LR4 LC-Duplex is a hot-pluggable optical module designed for 100 Gigabit Ethernet links over single-mode fiber. Using LR4 optics, it aggregates four independent 25 Gbps lanes into a single 100 Gbps interface and uses LC-duplex connectors for fiber connection. The module is intended for long-reach transmission, enabling reliable high-speed connectivity between core switches, aggregation devices and data center racks where single-mode fiber is deployed.

Advantages

This QSFP28 100G LR4 LC-Duplex transceiver supports hot-pluggable installation for minimal service interruption and uses four 25 Gbps channels to achieve 100 Gbps throughput. LR4 optics provide single-mode long-reach capability, and LC-duplex connectors offer broad compatibility with standard fiber cabling. The design focuses on stable link performance, interoperability with standard 100G Ethernet equipment and compact form factor suitable for high-density switch ports.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on your switch or router while the device is powered on or off, following the host equipment manufacturer’s instructions for hot-plug handling. Connect LC-duplex single-mode fiber cables to the transceiver ensuring correct polarity and secure connector seating. Configure the network equipment for 100G operation as required by your switch firmware or management software, and verify link status and diagnostics through the host interface. Follow standard fiber handling and ESD precautions during installation.

Recommendations

Use single-mode LC-duplex fiber with appropriate end-face cleanliness and correct polarity. Confirm compatibility with the host switch and verify optics settings such as lane mapping and link speed. Monitor link diagnostics and temperature through the host management interface to ensure stable long-reach performance.
