Fiber optic transceiver CBO BTI-40GLR-DD-QSFP 40G QSFP+ duplex LR

The Fiber optic transceiver CBO BTI-40GLR-DD-QSFP 40G QSFP+ duplex LR is a hot-pluggable 40 Gigabit Ethernet QSFP+ module designed for long-reach duplex links over single-mode fiber. It supports LR-class optics in a QSFP form factor, enabling 40 Gbps connections for data center uplinks, aggregation and core switch interfaces. The module is intended for straightforward installation in compatible QSFP+ ports and interoperates with standard LR single-mode fiber infrastructures to provide reliable long-distance connectivity.

Advantages

This 40G QSFP+ transceiver offers high-bandwidth transmission over long distances while maintaining low power consumption and a compact QSFP form factor. Hot-pluggable design allows replacement or upgrade without powering down equipment. The duplex LR optics support single-mode fiber links that are common in carrier and data center environments, providing predictable performance and wide equipment compatibility when used with standard-compliant network hardware.

Key specifications

How to use

Install the transceiver into a compatible QSFP+ port on a switch or router while the host device is powered on; the hot-pluggable design permits insertion and removal without shutting down equipment. Connect duplex single-mode fiber cables with LC connectors to the module, observing correct transmit/receive alignment. Ensure the host interface is configured for 40G operation and that transceiver firmware or vendor compatibility settings match the network device requirements. Monitor link status via device management tools to confirm a stable 40G connection.

Recommendations

Use certified single-mode fiber and clean LC connectors to minimize optical loss. Verify compatibility with the network device vendor's supported transceiver list and ensure appropriate configuration of link settings, including speed and duplex mode. For long-distance links, follow fiber routing best practices and perform optical power and BER testing during deployment.
