Fiber optic transceiver module BlueOptics X65402-BO 40000 Mbit/s QSFP 850 nm

The BlueOptics X65402-BO is a fiber optic transceiver module designed for high-speed short-reach applications. It supports a maximum data transfer rate of 40,000 Mbit/s over multimode fiber, uses a QSFP form factor and operates at an 850 nm wavelength. The module is compact and lightweight (approximately 20 g) and is RoHS compliant, offering a standardized interface for integration into compatible network equipment.

Advantages

The QSFP interface enables four-channel aggregation in a single compact module, providing a standardized, hot-pluggable solution for 40 Gbit/s links. Operation at 850 nm and compatibility with multimode fiber allow cost-effective short-range connections. The small size and low weight simplify installation and reduce port space requirements. RoHS compliance indicates reduced use of restricted substances and alignment with regulatory requirements.

Suitable for

• Data center uplinks and spine-leaf interconnects using multimode fiber
• High-throughput switching and routing ports that accept QSFP transceivers
• Storage area network (SAN) links and high-speed server interconnects
• Short-reach campus backbone segments and equipment interconnects up to typical multimode distances

How to use

Ensure that the target switch, router or storage device supports QSFP transceivers and the required 40 Gbit/s protocol. Handle the BlueOptics X65402-BO by the module housing and avoid touching the optical interfaces; keep protective caps on until connection. Insert the transceiver into the QSFP port until it latches, and connect MPO/MTP multimode fiber patch cables to establish the optical link. Verify link status and any digital diagnostics available on the host device. Follow the equipment vendor’s guidance for hot-plugging and firmware compatibility checks.

Usage recommendations

Use high-quality multimode MPO/MTP patch cables and, where applicable, correct fanout or breakout assemblies to ensure proper channel mapping. Confirm compatibility with the host hardware and enable Digital Diagnostics (DDM/DOM) support in the system to monitor supply voltage, laser bias and optical power where supported. For best performance, install in controlled environments with proper fiber management and follow the multimode fiber type and distance limits recommended by the system manufacturer.
