## Summary description

The BlueOptics QSFP28-850-SR4-BO is a fiber optic transceiver module designed for high-speed data transfer at 100000 Mbit/s. It features a QSFP28 interface and is made of durable metal housing. Weighing only 40 g, it is lightweight and easy to install. Ideal for data centers and high-performance networking applications.

## Long description

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.
Suitable for
100 Gbit/s short-reach Ethernet links in data centers
High-performance switch-to-switch or switch-to-server interconnects
Fibre Channel over Ethernet (FCoE) or SDH/SONET applications up to 100 m
Multi-mode fiber backbone and patch panel connections using MPO/MTP cabling
Key specifications
Interface: QSFP28
Nominal data rate: 100000 Mbit/s
Optical wavelength: 850 nm (Tx/Rx)
Maximum link distance: 100 m on multimode fiber
Connector type: MPO/MTP
Module housing: metal, silver colour
Weight: approx. 0.04 kg
Supports digital diagnostics monitoring (DDM/DOM)
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.
Usage 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.
