## Summary description

CBO QSFP-40G-LR4 compatible transceiver is a fiber optic module supporting 40 Gigabit Ethernet at 1310 nm wavelength. Designed for high-speed data links, it fits QSFP ports and enables long-reach optical connections. Suited for data centers and network cores, it provides reliable 40G transmission where QSFP compatibility and 1310nm operation are required.

## Long description

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.
Usage 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.
