Transceiver CBO QSFP28-100G-LR4 optický 100G LR4

The Transceiver CBO QSFP28-100G-LR4 Fiber Optic 100G LR4 is a QSFP28 form-factor module designed to deliver 100 Gbps long-reach links over single-mode fiber. It supports four-wavelength lanes aggregated to a single 100G channel, enabling high-bandwidth data transport for data center interconnects, enterprise backbone links and carrier networks. The module is compatible with standard QSFP28 ports and is intended for environments that require reliable, high-speed optical connectivity and gradual upgrades from 10G/40G to 100G infrastructure.

Advantages

This fiber optic transceiver provides 100 Gbps throughput with LR4 long-reach performance, reducing the number of parallel fibers required for high-capacity links. Its QSFP28 form factor supports hot-pluggable installation in compatible switches and routers, simplifying deployment and maintenance. The module is engineered for stable optical transmission over single-mode fiber, helping to support distance-sensitive connections and minimize link interruptions.

Suitable for

• Data center interconnects requiring 100G long-reach links
• Enterprise backbone and aggregation links
• Carrier and metro networks needing high-capacity single-mode fiber connections
• Network equipment upgrades from 10G/40G to 100G

Key specifications

• Form factor: QSFP28
• Optical interface: LR4 (long reach, 4 wavelengths)
• Nominal data rate: 100 Gbps
• Fiber type: single-mode fiber
• Transmission: four-wavelength multiplexed output
• Hot-pluggable: yes

How to use

Install the module into a compatible QSFP28 port on a switch or router while the host device is powered on to take advantage of the hot-pluggable capability. Connect single-mode duplex or MPO/MTP fiber as required by the host hardware and the LR4 optical interface. Verify link status and optical parameters through the host device management interface and monitor signal levels during initial commissioning to confirm expected performance.

Recommendations

Use clean single-mode fiber and appropriate fiber connectors; ensure fiber paths and connectors are free of dust and bends that exceed manufacturer bend-radius limits. Confirm host compatibility with QSFP28 LR4 modules and follow equipment vendor guidance for firmware and optics interoperability to maintain stable 100G links.
