QSFP transceiver module BlueOptics QSFP-40-SRBD-BO Fiber optic 100 m

The BlueOptics QSFP-40-SRBD-BO is a 40G QSFP fiber optic transceiver module designed for short-range multimode fiber links up to 100 m. Constructed with an aluminium housing and weighing approximately 40 g, this QSFP module uses LC duplex connectivity and supports bidirectional transmission for 40GBASE-SR2-BIDI applications. It is compatible with industry-standard QSFP interfaces and intended for use in network switches, routers and other hardware that accept QSFP form-factor transceivers.

Advantages

The module provides 40 Gbps data throughput over multimode fiber with bidirectional operation, allowing transmit and receive signals on a single pair of fibers. Its aluminium enclosure offers mechanical robustness while keeping the module lightweight. Compliance with QSFP MSA form-factor and LC duplex connections enable straightforward integration into existing fiber patching infrastructure. Designed to support Digital Diagnostics Monitoring (DDM/DOM) when supported by the host hardware, the transceiver facilitates remote status monitoring of optical parameters.

Suitable for

• Short-reach 40G network links in data centers and enterprise LANs
• Interconnects between switches and routers supporting QSFP modules
• High-bandwidth server or storage uplinks over multimode fiber

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Wavelength: bidirectional operation suitable for SR2-BIDI multimode use
• Maximum reach: up to 100 metres over multimode fiber
• Connector type: LC duplex
• Supported data rate: 40 Gbps (40GBASE-SR2-BIDI)
• Housing material and colour: aluminium / aluminium-coloured
• Weight: approximately 0.04 kg
• Digital diagnostics: DDM/DOM support when enabled by host

How to use

Install the BlueOptics QSFP-40-SRBD-BO by inserting it into a compatible QSFP port on a switch, router or other network device while the device is powered according to the host vendor guidelines. Connect LC duplex multimode fiber patch cords between transceivers or to a patch panel, taking care to align transmit and receive fibers correctly for bidirectional operation. Verify link status through the host device management interface and, if available, read DDM/DOM values for optical parameters such as temperature, supply voltage, transmit power and receive power.

Recommendations

Use high-quality multimode fiber and matched LC patch cords to achieve the specified 100 m range. Confirm host device compatibility with QSFP-40-SRBD modules and enable DDM/DOM in the host firmware to access diagnostic data. Avoid excessive bent radii on fiber cables and follow ESD precautions and vendor installation instructions when handling the transceiver.
