## Summary description

CBO QSFP28-100G-LR4 is a 100G LR4 fiber optic QSFP28 transceiver designed for single‑mode links up to 10 km. It provides four‑lane 25 Gbps optical transmission in a compact QSFP28 form factor, suitable for data center interconnects, core and aggregation switches, and high‑speed networking. Hot‑pluggable module for easy installation and replacement.

## Long description

The BlueOptics Fiber optic QSFP28 Transceiver CBO QSFP28-100G-LR4 100G LR4 single‑mode 10km is a hot-pluggable optical module that supports four 25 Gbps lanes to deliver 100 Gbps aggregate bandwidth over single‑mode fiber. Designed in the QSFP28 form factor, the transceiver enables long‑reach links up to 10 km and is compatible with data center interconnects, aggregation and core switches, and other high‑speed network equipment that accept QSFP28 LR4 optics.
Advantages
This transceiver offers a compact QSFP28 footprint with four independent optical lanes, enabling 100 Gbps transport while conserving port density. The single‑mode LR4 design provides stable performance for longer distances up to 10 km, and the hot‑pluggable capability allows tool‑free installation and replacement without shutting down host systems. The module is suitable for environments that require high throughput, predictable latency, and optical reach beyond short‑range multimode solutions.
Suitable for
Data center interconnects and spine‑leaf architectures
Core and aggregation switch uplinks
Carrier and metro network links requiring 10 km reach
High‑performance computing clusters and storage networks
Key specifications
Form factor: QSFP28 supporting 4×25 Gbps lanes
Aggregate data rate: 100 Gbps
Optical type: single‑mode fiber
Reach: up to 10 km over single‑mode fiber
Wavelength: four‑lane LR4 wavelength division multiplexing
Interface: duplex LC connector (or appropriate QSFP28 breakout adapter)
Hot‑pluggable: yes
Typical power consumption: industry‑standard range for QSFP28 modules
How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on the host switch or router while the device is powered on; the hot‑pluggable design permits insertion and removal without shutting down the system. Connect single‑mode fiber using LC duplex patch cords or an appropriate breakout assembly and verify link status via the host equipment management interface. Ensure the optical fiber path is clean and that transceiver and host firmware or driver support the LR4 QSFP28 profile.
Usage recommendations
Use single‑mode LC patch cords rated for LR4 wavelengths and maintain fiber cleanliness to preserve signal quality. Verify compatibility with the host device and, if necessary, use vendor‑approved transceiver settings or firmware to ensure proper link negotiation and performance over distances up to 10 km.
