Transceiver CBO QSFP-40G-LR4 compatible fiber optic 40G 1310nm

The Transceiver CBO QSFP-40G-LR4 compatible fiber optic 40G 1310nm is a hot-pluggable optical module designed for 40 Gigabit Ethernet links. It supports QSFP form factor connectivity and operates at a nominal wavelength around 1310 nm to enable long-reach single-mode fiber transmission. The module is intended for installation in switches, routers and transponder equipment that accept compatible QSFP optics and where reliable 40G transport over extended distances is required.

Advantages

This QSFP-40G-LR4 compatible transceiver offers standardized QSFP interoperability, allowing straightforward replacement or upgrade of existing optics. The module’s single-mode 1310 nm operation provides extended reach compared with short-reach optics while maintaining stable signal characteristics for 40G Ethernet. Its compact QSFP package supports high port density in data center and telecom chassis and simplifies deployment with hot-pluggable installation.

Suitable for

• 40 Gigabit Ethernet uplinks in data centers and campus networks
• Core and aggregation layer connectivity between switches and routers
• Long-reach single-mode fiber links requiring QSFP-compatible optics
• Service provider and metro connections where 40G LR4 performance is needed

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate
• Optical type: single-mode fiber
• Wavelength: nominal 1310 nm
• Interface: duplex optical connection via LC or MPO-type adapter (depending on system implementation)
• Supported protocol: 40 Gigabit Ethernet
• Operation: hot-pluggable

How to use

Install the transceiver into a compatible QSFP port on your network device while the equipment is powered according to your system manual to ensure hot-plug safety. Connect the single-mode fiber patch cable appropriate for the transceiver’s connector type and ensure correct TX/RX orientation. After physical installation, verify link status and configuration in the switch or router management interface; confirm that the port is operating at 40 Gbps and that optical diagnostics (if available) report acceptable power and temperature values.

Recommendations

Ensure compatibility with the host device’s optics policy before deployment and use single-mode fiber with suitable connectors and quality polishing to achieve reliable LR4 performance. Observe ESD precautions when handling the transceiver and avoid bending fiber beyond recommended radii to prevent signal degradation.
