Transceiver CBO QSFP28-100G-LR4 Fiber Optic 100G LR4

The Transceiver CBO QSFP28-100G-LR4 Fiber Optic 100G LR4 is a QSFP28 form-factor module designed to deliver 100 gigabit per second links over single-mode fiber for long-reach applications. The module is compatible with standard QSFP28 ports and provides a reliable optical interface for data center, carrier and enterprise environments where high-throughput, low-latency connections are required. It supports LR4 wavelength-division multiplexing to transmit 100G traffic across extended distances using single-mode fiber infrastructure.

Advantages

This QSFP28 LR4 transceiver offers high-density 100G connectivity in a compact form factor with straightforward hot-pluggable installation into QSFP28-capable equipment. It provides long-reach single-mode operation suitable for inter-rack, inter-data-center or metro links and is designed to support stable throughput and compatibility with standard QSFP28 interfaces. The module reduces the need for multiple lower-speed ports by consolidating traffic into a single 100G link.

Suitable for

• Data center uplinks and spine-to-leaf interconnects
• Carrier and metro network long-reach links
• Enterprise campus backbone connections
• High-throughput switch-to-router links

Key specifications

• Form factor: QSFP28
• Nominal data rate: 100 Gbps
• Media type: Single-mode fiber (SMF)
• Transmission type: LR4 (4-lane wavelength-division multiplexing)
• Reach: long-reach distances over single-mode fiber (typical for LR4 optics)
• Connector type: duplex LC (requires appropriate adapter or breakout as applicable)

How to use

Install the transceiver into a compatible QSFP28 port on a switch, router or optical aggregation device while the host device is powered on or following the host vendor's hot-swap guidance. Connect single-mode fiber with the appropriate LC duplex connectors or use an approved breakout cable or adapter if connecting to multi-lane interfaces. Verify link status and proper lane alignment via the host system management interface and monitor optical power levels and error counters to ensure correct operation.

Recommendations

Use clean, certified single-mode fiber and LC connectors, keep transceiver dust caps in place until installation, and follow ESD precautions when handling the module. Confirm compatibility with the host equipment's QSFP28 ports and firmware, and validate link parameters after installation to ensure reliable 100G LR4 operation.
