QSFP Transceiver Module BlueOptics QSFP-40G-LR4-IX-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-IX-BO is a QSFP fiber optic transceiver module designed for single-mode optical links up to 40 Mbit/s. Housed in a metal casing and weighing 20 g, the module uses an LC Duplex connector and supports CWDM-based transmit and receive channels for long-reach optical transmission. The module follows QSFP MSA form-factor conventions to ensure electrical and mechanical interoperability with compatible network equipment.

Advantages

The transceiver provides a compact QSFP form factor with LC Duplex connectivity and CWDM-enabled transmit/receive paths, enabling simultaneous send and receive over single-mode fiber. Metal housing offers mechanical robustness and thermal conductivity for steady operation. Digital Diagnostics Monitoring (DDM/DOM) capability allows real-time reporting of supply voltage, laser bias current, optical output power, received power and temperature when supported by host hardware.

Suitable for

• 40G optical uplinks and interconnects in switches and routers
• High-speed links between storage systems and network infrastructure
• Long-reach single-mode fiber connections requiring LC Duplex interfaces
• Environments where DDM/DOM-based monitoring is used for link diagnostics

How to use

Install the QSFP module into a compatible QSFP port on a switch, router or other networking device while the host device is powered down or following the vendor’s hot-plug instructions. Connect LC Duplex single-mode fiber patch cords between transceivers or into a fiber patch panel, ensuring correct polarity and secure ferrule seating. Verify link status in the host device management interface and, if available, read DDM/DOM values to confirm optical levels and operating temperature. Follow the equipment vendor’s firmware and compatibility guidelines to ensure proper recognition and operation.

Recommendations

Use single-mode LC Duplex patch cords sized and specified for LR4 applications and verify that the host hardware supports the QSFP MSA form factor and DDM/DOM for full functionality. Avoid excessive bending of fiber and ensure clean connectors to maintain optimal optical performance.
