QSFP transceiver modul BlueOptics QSFP-40G-ER4L-NV-BO 40 Mbit/s 1310 nm

The BlueOptics QSFP-40G-ER4L-NV-BO is a QSFP fiber optic transceiver module designed for single-mode links with a nominal wavelength of 1310 nm and a maximum data transfer rate of 40 Mbit/s. It features an LC duplex fiber connector, a compact QSFP interface and a lightweight form factor of approximately 40 g. The module is specified to operate over long distances up to 30,000 m and is built to meet multi-source agreement (MSA) mechanical and electrical standards for QSFP pluggable optics.

Advantages

This transceiver supports long-reach single-mode optical links with an LC duplex interface, enabling simultaneous transmit and receive on separate fibers. It includes digital diagnostics monitoring (DDM/DOM) capability for remote measurement of parameters such as optical power and temperature when the host supports the feature. The module is produced to industry standards and is compatible with hardware that accepts QSFP MSA form-factor modules, offering a reliable option for deployments that require extended-range optical connectivity.

Suitable for

• Long-distance single-mode fiber interconnects
• High-speed network links up to 40 Mbit/s
• Data center uplinks and aggregation links
• Switches, routers and storage systems with QSFP ports

Key specifications

• Maximum data transfer rate: 40 Mbit/s
• Maximum transfer distance: 30,000 m (single-mode fiber)
• Connector type: LC duplex
• Weight: 0.04 kg
• Digital diagnostics monitoring (DDM/DOM): supported when host hardware provides access

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch, router or storage device following the host manufacturer's guidance for hot-plugging and handling of optical modules. Connect LC duplex single-mode fiber patch cords to the transmit and receive ports, ensuring correct polarity. Verify link status and, if available, access digital diagnostics via the host interface to confirm optical power levels and operating temperature. Use appropriate fiber management (patch panels, bend-radius control) to maintain link quality.

Recommendations

For optimum performance, pair the module with single-mode LC duplex fiber of suitable quality and ensure link loss budgets are met for the stated 30 km reach. Confirm that the host device supports the QSFP form factor and DDM/DOM functions if remote monitoring is required. Handle the transceiver with electrostatic discharge precautions and store unused ports covered to avoid contamination of optical interfaces.
