40GBASE-LR4-SS-BO network transceiver module BlueOptics 40 Mbit/s QSFP

The BlueOptics 40GBASE-LR4-SS-BO network transceiver module is a QSFP fiber optic module designed for 40 Mbit/s optical data links over single-mode fiber. It implements the LR4 optical interface with LC Duplex connectivity and is intended for use in QSFP-capable network equipment. The module is lightweight (approximately 20 g) and specified with a mean time between failures (MTBF) of 1,000,000 hours, providing a compact option for high-speed optical interconnects.

Advantages

This transceiver uses a standardized QSFP electrical and mechanical interface to ensure interoperability with compatible switches, routers and storage systems that accept QSFP modules. The LR4 optical design supports simultaneous transmit and receive channels over single-mode fiber via LC Duplex connectors. The product is manufactured to industry MSA guidelines and includes digital diagnostic capabilities where supported by host hardware, enabling remote monitoring of key optical parameters. Low weight and a high MTBF contribute to reduced maintenance and long operational availability in installed networks.

Suitable for

• Fiber optic uplinks between QSFP-capable switches and routers
• High-speed links in data center aggregation and spine-leaf architectures
• Interconnection of storage systems and network appliances with QSFP ports
• Long-reach single-mode fiber links where LC Duplex connections are used

Key specifications

• Interface type: QSFP
• Maximum data transfer rate: 40 Mbit/s
• Optical connector: LC Duplex (single-mode fiber)
• Typical weight: 0.02 kg
• MTBF: 1,000,000 hours

How to use

Insert the QSFP transceiver into a compatible QSFP cage on the host device until it seats firmly and the latch engages. Connect single-mode LC Duplex fibre patch cords to the transmit and receive ports, ensuring correct polarity. Verify that the host system recognizes the module and, if available, enable or read out digital diagnostics (DDM/DOM) from the host management interface to monitor supply voltage, laser bias current, optical power and temperature. Follow the host equipment vendor’s instructions for hot-plug handling and firmware compatibility.

Recommendations

Use certified single-mode LC Duplex patch cords and proper cable management to maintain optical performance. Confirm that the target hardware supports the LR4 QSFP optical specification and DDM/DOM functionality for monitoring. Avoid bending fiber beyond recommended radii and protect connectors from dust; clean connectors before mating to reduce insertion loss and ensure optimal link quality.
