QSFP Transceiver Module BlueOptics QSFP-40G-LR4-20-LE-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-LE-BO is a QSFP fiber optic transceiver module engineered for high-speed, long-reach optical links. With a maximum data transfer rate of 40 Gbit/s and support for LC connectors, this compact module is intended for use in data center and enterprise network environments where reliable 40 Gigabit Ethernet or similar high-bandwidth optical connections are required. Weighing approximately 40 g and specified for single-mode long-distance transmission up to 20,000 m, it provides the physical interface and optical performance necessary to extend network links between racks, aggregation switches, and core equipment.

Advantages

The module combines a standard QSFP form factor with LR4 optical technology to deliver stable 40 Gbit/s links over long distances using LC fiber connections. Its compact and lightweight design facilitates dense port deployments in switches and transceivers bays while minimizing mechanical load. The transceiver conforms to common QSFP interoperability expectations, offering predictable optical reach and straightforward installation for network technicians managing high-capacity links.

How to use

Install the QSFP-40G-LR4-20-LE-BO into a compatible QSFP port on a switch, router, or transponder following the host device manufacturer's hot-swap and insertion guidance. Connect single-mode LC fiber cables to the module, ensuring correct transmit/receive alignment and clean connectors to maintain optical performance. After physical installation, verify link status and configure the host port for the required 40 Gbit/s operation, monitor optical power levels and error statistics through the host management interface as part of acceptance testing.

Recommendations

Use single-mode fiber with appropriate LC connectors and keep connectors clean and dust-free. Verify compatibility with the host device's QSFP port and firmware, and perform optical power and link tests after installation. For long-distance links, plan for proper fiber routing, strain relief, and environmental protection to maintain signal integrity over the full reach.
