## Summary description

CBO QSFP28 100G LR4 LC-Duplex transceiver is a hot-pluggable module for 100 Gigabit Ethernet links using LR4 optics and LC-duplex fiber connectors. Designed for long-reach single-mode fiber, it provides four-channel 25 Gbps lanes aggregated to 100 Gbps. Suitable for data centers, core and aggregation switches, and high-speed links requiring long-distance transmission.

## Long description

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.
Suitable for
 100 Gigabit Ethernet links between data center switches and routers
 Long-reach single-mode fiber connections in enterprise and carrier networks
 Core and aggregation layer interconnects requiring 100G bandwidth
 High-speed uplinks in campus or service provider environments
Key specifications

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.
Usage 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.
