QSFP28 Transceiver BlueOptics QSFP28-850-SR4-BO 100000 Mbit/s

The BlueOptics QSFP28-850-SR4-BO is a 100GBASE-SR4 fiber optic transceiver module with a QSFP28 interface, designed for high-speed data transfer at up to 100000 Mbit/s over multimode fiber. Housed in a durable metal enclosure and weighing approximately 40 g, the module uses an MPO/MTP connector and operates at 850 nm for both transmitter and receiver. It supports short-reach links up to 100 m and is suitable for installation in compatible QSFP28 ports on switches, routers and storage systems that accept SR4 modules.

Advantages

The module conforms to common MSA QSFP28 mechanical and electrical specifications and is compatible with hardware platforms that support 100GBASE-SR4 optics. Its metal housing provides mechanical robustness and thermal conduction for stable operation. The MPO/MTP connector accommodates parallel multimode fiber links and enables simultaneous transmit and receive lanes. Built-in digital diagnostics (DDM/DOM) allow monitoring of supply voltage, laser bias current, transmit output power, receive input power and temperature for easier fault finding and remote maintenance.

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port until it latches, following the host device manufacturer’s installation procedure. Connect the MPO/MTP multimode fiber patch cord to the module and ensure correct polarity and fiber type (multimode, suitable for 850 nm). After installation, verify link status and diagnostics via the host system. Observe ESD precautions during handling and allow the device to operate in the temperature range and environment specified by the host hardware.

Recommendations

For optimal performance, use multimode fiber and MPO/MTP patch cords rated for 100GBASE-SR4, keep connectors and fiber endfaces clean, and confirm that the host equipment supports SR4 optics and DDM/DOM functions. When replacing modules in production environments, test links and, if possible, evaluate a sample in the target switch or router to confirm compatibility and expected link performance.
