BlueOptics MA-QSFP-40G-SR-BD-BO network transceiver module QSFP 100m

The BlueOptics MA-QSFP-40G-SR-BD-BO network transceiver module is a QSFP form-factor optical module designed for short-reach multi-mode applications up to 100 meters. Its aluminium housing and compact 40 g weight make it suitable for high-density network environments where 40 Gbps lanes are required. The module implements bidirectional 40GBASE-SR2-BIDI signaling over LC duplex connectors and is intended for use in switches, routers and other networking hardware that support QSFP 40G short-range optics.

Advantages

The module delivers 40 Gbps optical data transmission over multimode fiber with bidirectional channels, allowing simultaneous send and receive through a single LC duplex interface. Lightweight aluminium construction aids in thermal dissipation and rack‑scale deployments, while compliance with common MSA QSFP mechanical and electrical specifications ensures interoperability with equipment that supports 40GBASE-SR2 BIDI optics. Digital diagnostics (DDM/DOM) support enables real-time monitoring of supply voltage, laser bias current, output and received optical power, and temperature for easier maintenance and troubleshooting.

Suitable for

• 40 Gbps aggregation links in data center switches and spine-leaf architectures
• High-speed connections between routers, storage arrays and switches within a rack or between adjacent racks (up to 100 m)
• Latency-sensitive Ethernet and Fibre Channel over Ethernet (FCoE) short-reach links

• Digital diagnostics: DDM/DOM support (MSA SFF-8472 compliant)

How to use

Insert the QSFP transceiver into a compatible QSFP port on your switch, router or storage device while the host system is powered according to the vendor's guidance. Connect LC duplex multimode fiber patch cords between transceivers or to patch panels ensuring correct fiber type and polarity for bidirectional SR2 BIDI operation. Verify link status via the host device interface and, if available, read DDM/DOM parameters from the system to confirm optical power levels and temperature are within expected ranges. Follow the equipment manufacturer's procedures for hot-plugging and firmware compatibility when installing third-party transceivers.

Recommendations

Use OM3/OM4 multimode fiber for best performance up to the specified 100 m range, keep connectors clean and dry, and avoid sharp bends in patch cords. Confirm that the target hardware supports third-party QSFP 40GBASE-SR2-BIDI modules and enable DDM/DOM monitoring in the host system to assist with diagnostics and preventive maintenance.
