## Summary description

The BlueOptics QSFP-100G-SR4-ET-BO is a fiber optic transceiver module designed for high-speed data transfer at 100000 Mbit/s. It operates at a wavelength of 850 nm and is compatible with QSFP28 interfaces. With a compact design and lightweight of 4 g, it is ideal for data centers and high-performance computing environments. The input voltage is 3.3 V, making it efficient for various applications.

## Long description

The BlueOptics QSFP-100G-SR4-ET-BO is a 100G QSFP28 fiber optic transceiver designed for short-reach multimode links. It supports a maximum data rate of 100000 Mbit/s using 850 nm transmit and receive lasers and connects via an MPO/MTP interface according to MSA QSFP28 standards. The compact, lightweight module (approx. 4 g) operates from a 3.3 V supply and is intended for integration into data center switches, routers and high-performance computing platforms that accept QSFP28 SR4 optics.
Advantages
The module provides high-bandwidth 100GBASE-SR4 connectivity over multimode fiber for distances up to the multimode limits specified by SR4 standards. Compliance with MSA pinout and MPO/MTP connector conventions ensures interoperability with major hardware platforms that support QSFP-100G-SR4 optics. Integrated digital diagnostics (DDM/DOM) supports real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature, aiding remote maintenance. The small form factor and low weight simplify port density planning and airflow considerations in densely populated racks.
Suitable for
Short-reach 100G Ethernet links in data center top-of-rack and spine architectures
High-performance computing and storage interconnects using multimode fiber
Upgrading switch or router ports to 100G in equipment that supports QSFP28 SR4 optics
Environments where digital diagnostics are required for link monitoring and troubleshooting
Key specifications

Optical wavelength: 850 nm (Tx and Rx)
Fiber type: Multimode fiber (MMF), SR4 optical standard
Power supply: 3.3 V input
Form factor weight: approximately 0.004 kg (4 g)
Product colour: silver
Digital Diagnostics Monitoring (DDM/DOM) support for real-time status
How to use
Install the QSFP-100G-SR4-ET-BO module into a compatible QSFP28 port following the host equipment manufacturer’s hot-plugging and ESD handling procedures. Terminate the module with an MPO/MTP multimode fiber patch cord and ensure fiber polarity and connector cleanliness before establishing the link. Confirm that the host device firmware and software accept SR4 optics and enable any DDM/DOM monitoring functions if required. After insertion, verify link status and transmit/receive counters via the switch or router management interface.
Usage recommendations
Use OM3 or OM4 multimode fiber for optimal reach and performance with SR4 optics, and clean connectors before mating. Verify host compatibility with QSFP-100G-SR4 modules and enable DDM/DOM monitoring to assist with diagnostics. Follow manufacturer guidelines for handling and insertion to avoid damage from ESD or improper force.
