40G QSFP transceiver BlueOptics 40G-QSFP-LR4-KY-BO 40000 Mbit/s

The BlueOptics 40G-QSFP-LR4-KY-BO is a fiber optic transceiver module designed for 40 Gbit/s Ethernet links. It uses a QSFP form factor and QSFP interface to provide high-bandwidth optical connectivity over single-mode fiber. The module is finished in silver and is intended for use in compatible switches, routers and optical equipment where LR4 (long-reach) transmission is required. The device is compliant with CE, FCC and RoHS standards and has a stated MTBF of 1,000,000 hours, offering predictable operational reliability for data center and enterprise network environments.

Advantages

The transceiver supports a maximum data transfer rate of 40,000 Mbit/s using an industry-standard QSFP interface, enabling aggregation of high-speed links. Its QSFP form factor provides compact installation into compatible ports while maintaining thermal and mechanical stability. Compliance with international safety and environmental standards ensures interoperability and regulatory conformance. A high MTBF rating indicates long-term reliability and reduced maintenance frequency in continuous-operation installations.

Suitable for

• 40 Gbit/s uplinks between switches in data centers
• High-capacity server to switch connections
• Optical aggregation and backbone links over single-mode fiber

How to use

Power down or follow hot-swap procedures recommended by the network device vendor before inserting or removing the QSFP transceiver. Insert the module into a compatible QSFP port until it seats firmly and the retention mechanism engages. Connect appropriate single-mode fiber patch cords to the optical receptacle, observing correct polarity. Configure the host device for a 40 Gbit/s LR4 optical interface as required by the switch or router operating system, and verify link status and diagnostics via the equipment management interface.

Recommendations

Handle the optical connector ends with care and keep protective caps on when not in use to avoid contamination. Ensure compatible optical cable type and connector standards for LR4 operation, and verify vendor compatibility lists if used in third-party equipment. Monitor module temperature and link diagnostics during initial deployment to confirm stable operation.
