40G QSFP Transceiver Module BlueOptics 40G-QSFP-ER4-1-BO Fiber Optic

The BlueOptics 40G-QSFP-ER4-1-BO is a 40G QSFP fiber optic transceiver module designed for long-distance single-mode transmission. It implements the QSFP interface and LC Duplex connectivity and is constructed in an aluminium housing with a lightweight design (approximately 40 g). The module supports high-speed optical links up to 40 Gbit/s and is intended for use in data center and carrier-class network environments where reliable point-to-point connections over long spans are required.

Advantages

This transceiver supports 40GBASE-ER4 class transmission over single-mode fiber with a duplex LC connector and is built to MSA-compatible QSFP mechanical and electrical standards. Its aluminium housing provides mechanical stability and thermal dissipation while keeping weight low. The module includes digital diagnostics/DOM capability to report supply voltage, laser bias current, transmit power, receive power and temperature in real time, enabling remote monitoring and easier troubleshooting. The design targets interoperability with network platforms that accept 40G QSFP ER4 transceivers.

Suitable for

• Long-reach 40 Gbit/s point-to-point links in data centers and core networks
• Interconnection of switches, routers and storage systems supporting QSFP ER4 modules
• High-performance network segments requiring single-mode fiber links up to tens of kilometers

Key specifications

• Nominal data rate: 40 Gbit/s
• Form factor: QSFP
• Connector: LC Duplex
• Transmission medium: Single-mode fiber
• Typical reach: designed for long-reach/ER4 class links (tens of kilometers)
• Housing material: aluminium
• Approximate weight: 0.04 kg
• Digital diagnostics (DOM/DDM) supported for status monitoring

How to use

Install the BlueOptics 40G-QSFP-ER4-1-BO into a compatible QSFP socket on a switch, router or other network device that supports 40GBASE-ER4 QSFP modules. Connect single-mode LC Duplex patch cords to the transceiver ports, ensuring correct transmit/receive alignment. Verify that the host device supports digital diagnostics if you intend to use DOM functions. After insertion, check link status and diagnostic parameters via the host management interface to confirm proper operation.

Recommendations

Use quality single-mode LC Duplex fiber patch cords and, where appropriate, a patch panel to preserve link performance. Ensure the network hardware firmware and settings are compatible with 40GBASE-ER4 QSFP modules and enable DOM only if supported by the platform. Avoid exposing the optical connectors to dust and clean with suitable fiber cleaning tools before connection.
