Fiber optic QSFP28 Transceiver CBO QSFP28-100G-LR4 100G LR4 single‑mode 10km

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.

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.
