QSFP28 Transceiver BlueOptics QSFP28-100G-SR4-MT 100G 850nm

The BlueOptics QSFP28-100G-SR4-MT is a 100G fiber optic transceiver module designed for short-range, high-bandwidth connections in data centers and high-performance computing environments. Operating at an 850 nm wavelength and using the QSFP28 interface, this compact module supports 100 Gbit/s aggregate data throughput while remaining lightweight at approximately 40 g. Its form factor and electrical/optical compatibility make it suitable for QSFP28 ports in switches, routers and optical line cards where multimode fiber and MPO/MTP connectivity are used.

Advantages

The module provides reliable 100G transmission over multimode fiber at 850 nm and complies with QSFP28 form-factor expectations for hot-pluggable installation. Its small size and low weight simplify handling and installation in dense rack environments. The standardized interface ensures broad interoperability with networking equipment that supports QSFP28 transceivers, while the use of multimode optics reduces cost for short-reach links within campus and data center infrastructures.

Suitable for

• Short-reach 100G links in data centers
• Top-of-rack and spine switch connections

How to use

Install the transceiver into a compatible QSFP28 port on the network device while the device is powered according to the host equipment manual for hot-pluggable modules. Connect the multimode MPO/MTP fiber cable to the module’s connector, ensuring correct polarity and clean fiber endfaces to maintain signal integrity. Verify that the link is recognized by the host and monitor link status and error counters through the switch or router management interface.

Recommendations

Use multimode OM3/OM4 fiber for optimal 100G SR4 reach and performance, keep fiber connectors clean, and comply with the host equipment’s supported transceiver list when deploying the BlueOptics QSFP28-100G-SR4-MT.
