Transceptor CBO QSFP-40G-LR4 compatível QSFP, 40G LR4 Módulo de fibra ótica

The Transceiver CBO QSFP-40G-LR4 compatible QSFP, 40G LR4 fiber optic module is a hot-pluggable 40 Gigabit LR4 transceiver designed for long-reach single-mode fiber links. It fits QSFP form-factor ports on switches, routers and optical transport equipment and provides aggregate data rates up to 40Gbps. The module is intended for use in data center uplinks, campus backbone connections and service provider networks requiring reliable long-distance fiber connectivity.

Advantages

This compatible QSFP LR4 transceiver offers high-density 40Gbps connectivity in a compact QSFP package, enabling efficient use of rack and chassis ports. It supports long-reach single-mode fiber links to extend network segments without intermediate regeneration. The device follows standard QSFP LR4 electrical and optical interfaces for broad interoperability with equipment that accepts LR4 QSFP modules. Its hot-pluggable design simplifies installation and replacement with minimal service interruption.

Suitable for

• Data center uplinks between aggregation and core switches
• Campus backbone links over single-mode fiber
• Carrier and metropolitan area network connections
• High-speed links between routers and optical transport equipment

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate (4 × 10 Gbps lanes)
• Optical reach: LR4 long-reach single-mode fiber support
• Wavelengths: Four-channel LR4 wavelength multiplexing
• Connector type: Duplex LC (typical for LR4 single-mode links)
• Hot-pluggable QSFP interface for easy installation

How to use

Install the QSFP-40G-LR4-compatible transceiver into a compatible QSFP port on your switch, router or optical device while the host supports QSFP LR4 modules. Connect single-mode duplex LC fiber patch cables between the module and the remote endpoint, ensuring correct TX/RX orientation. Verify link status in the host device management interface and confirm that the port is configured for 40Gbps operation or appropriate breakout settings if using lane breakout. Follow vendor guidelines for ESD protection and safe handling when inserting or removing the module.

Recommendations

Use certified single-mode fiber with appropriate attenuation budgets and LC connectors for LR4 links. Verify fiber length and loss budgets against LR4 reach specifications, and ensure host equipment firmware supports compatible QSFP LR4 modules to avoid compatibility issues.
