## Summary description

CBO QSFP28-100G-LR4 is a fiber-optic 100G LR4 QSFP28 transceiver designed for long-reach Ethernet and data center links. It supports 100 Gigabit per second transmission over single-mode fiber using the LR4 specification. Suitable for high-speed backbone, metro and inter-rack connections, it provides reliable optical connectivity for network equipment compatible with QSFP28 modules.

## Long description

The Transceiver CBO QSFP28-100G-LR4 Fiber Optic 100G LR4 is a QSFP28-form-factor optical module designed for single-mode fiber links operating at 100 Gigabit Ethernet LR4 specification. It converts electrical signals to four optical lanes and back, enabling 100 Gbps aggregate throughput for long-reach connections between switches, routers and other data centre or metro network equipment compatible with QSFP28 modules.
Advantages
This QSFP28 LR4 transceiver offers long-reach single-mode performance, compact QSFP28 form factor for high-density installations, and compatibility with standard 100G LR4 optical interfaces. Its four-lane optical design supports reliable high-speed transmission over single-mode fiber, and the module is suitable for use in common network equipment that accepts QSFP28 optics, facilitating scalable upgrades of backbone and inter-rack links.
Suitable for
100 Gigabit Ethernet long-reach links over single-mode fiber
Data centre spine and leaf connections between racks and switches
Metro aggregation and long-distance interconnects within carrier networks
High-density switch ports requiring QSFP28 optical modules
Key specifications
Form factor: QSFP28
Data rate: 100 Gbps aggregate
Optical interface: LR4 (long reach, four wavelengths)
Fiber type: Single-mode fiber (SMF)
Wavelength: Four lanes in LR4 wavelength band
Connector: Duplex LC (typically used with LC duplex or MPO-LC breakout as applicable)
Operating environment: Designed for standard data centre and carrier ambient conditions
How to use
Install the transceiver into a QSFP28-compatible port on your switch or router while the host device is powered down or following hot-plug procedures recommended by the equipment vendor. Connect single-mode fiber patch cords or an MPO breakout assembly as required for LR4 optics, ensuring correct polarity and secure connector seating. Verify link status and module diagnostics through the host device interface and monitor optical power and error counters to confirm proper operation.
Usage recommendations
Use factory-tested single-mode fiber of appropriate attenuation and follow connector cleaning best practices to maintain signal integrity. Confirm host hardware compatibility with QSFP28 LR4 modules and, when deploying in high-density environments, plan for thermal management according to the switch manufacturer’s guidelines.
