Fiber optic transceiver module BlueOptics X65405-BO 100000 Mbit/s QSFP28

The BlueOptics X65405-BO is a fiber optic transceiver module designed for high-speed data transfer up to 100000 Mbit/s. It uses a QSFP28 interface and transmits at an 850 nm wavelength over multimode fiber with an MPO/MTP connector. The module is RoHS compliant, weighs 40 g and is intended for integration into networking equipment that supports QSFP28 100GBASE-SR4 optics. It supports Ethernet and similar high-speed protocols and is compatible with hardware platforms that accept equivalent 100GBASE-SR4 QSFP28 transceivers.

Advantages

The transceiver provides 100 Gbit/s capacity in a compact QSFP28 form factor, enabling dense aggregation of high-bandwidth links while maintaining small physical footprint. Use of an 850 nm transmitter/receiver pair and MPO/MTP connection allows simultaneous multi-lane optical communication over multimode fiber for short-reach links. RoHS compliance and a lightweight silver housing make the module suitable for modern data centre deployments where environmental standards and efficient rack density are required.

Suitable for

• 100 Gbit/s switch-to-switch and switch-to-server interconnects
• Short-reach multimode fiber links up to approximately 100 m
• High-bandwidth aggregation in data centers and campus networks
• Replacement or expansion in systems supporting 100GBASE-SR4 QSFP28 optics

How to use

Install the module into a compatible QSFP28 port on network equipment while the device is powered off or following the vendor’s hot-plug procedures. Connect an MPO/MTP multimode fiber patch cord matched to the transceiver and the receiving end. Ensure the link partner supports 100GBASE-SR4 or an equivalent QSFP28 optic and verify that device firmware or software does not block third-party modules. After insertion and cable connection, confirm the link status and, if available, read digital diagnostics to verify operating parameters.

Usage recommendations

Use high-quality multimode fiber (OM3/OM4) and MPO/MTP patch cords for optimal performance and reach. Verify support for Digital Diagnostics Monitoring (DDM/DOM) on your hardware to monitor supply voltage, laser bias current, optical transmit/receive power and temperature. Follow manufacturer guidelines for ESD protection during handling and ensure firmware compatibility to avoid interoperability issues.
