## Summary description

The BlueOptics QSFP28-SR4-CI-BO is a fiber optic transceiver module designed for high-speed data transfer. It supports a maximum distance of 100 meters and features a QSFP28 interface. The module is lightweight at 40g and comes in an aluminum casing, ensuring durability and reliability in data communication applications.

## Long description

The BlueOptics QSFP28-SR4-CI-BO is a 100G QSFP28 multimode fiber optic transceiver designed for short-reach data transmission up to 100 meters over MPO/MTP connections. Encased in aluminium and weighing 40 g, the module follows MSA mechanical and electrical specifications for QSFP28 form factor and supports transmission and reception at 850 nm. It is intended for use in network equipment that accepts QSFP28 100GBASE-SR4 modules and supports high-speed Ethernet, Fibre Channel over Ethernet or SDH/SONET applications.
Advantages
The module provides 100G aggregate data throughput in a compact QSFP28 form factor and is compatible with MPO/MTP multimode fibre cabling. Aluminium housing offers mechanical protection and thermal conduction. Built to MSA standards, the transceiver includes digital diagnostic monitoring (DDM/DOM) for real-time reporting of supply voltage, laser bias current, optical transmit/receive power and temperature when supported by host hardware. The module is lightweight and suitable for dense data centre or enterprise installations that require short-range, high-bandwidth interconnects.
Suitable for
100G short-reach connections in data centre top-of-rack and spine switches
Interconnects between routers, storage systems and load balancers within a single building or campus
High-speed Ethernet and Fibre Channel over Ethernet links up to 100 meters on multimode fiber
Replacing or upgrading QSFP28 100GBASE-SR4 ports in compatible network platforms
Key specifications
Form factor: QSFP28 multimode transceiver
Max. reach: up to 100 meters on multimode fiber
Optical wavelength: 850 nm transmit and receive
Connector type: MPO/MTP multi-fiber connector
Supported protocols: 100GBASE-SR4 (Ethernet), Fibre Channel over Ethernet, SDH/SONET
Material: aluminium housing
Weight: 0.04 kg
Digital diagnostics: DDM/DOM support (if host supports feature)
How to use
Install the QSFP28-SR4-CI-BO into a compatible QSFP28 port following the host equipment manufacturer’s hot-plug and handling instructions. Connect an MPO/MTP multimode fiber patch cord to the module and ensure correct polarity and fiber type (multimode). Confirm that the network device firmware and transceiver settings accept third-party QSFP28 modules and enable digital diagnostics if monitoring is required. After insertion, verify link status and data rate through the host system management interface.
Usage recommendations
Use OM3/OM4 multimode fiber for the specified 100 m range and keep fiber connectors clean to maintain optical performance. Verify host compatibility and, when available, enable DDM/DOM for proactive monitoring of optical parameters. Follow ESD precautions and manufacturer instructions during handling and installation.
