## Summary description

The BlueOptics QSFP-100G-SR4-S is a fiber optic network transceiver module designed for high-speed data transfer at 100000 Mbit/s. It operates at a wavelength of 850 nm and utilizes the QSFP28 interface. Weighing only 40 g, it is compact and efficient, making it suitable for various networking applications.

## Long description

The BlueOptics QSFP-100G-SR4-S network transceiver module is a compact QSFP28-form factor device engineered for short-reach 100 Gbit/s fiber connections. Operating at an 850 nm wavelength, this module supports multimode fiber links and delivers a maximum data transfer rate of 100000 Mbit/s while maintaining a low weight of 40 g. Its QSFP28 interface provides a high-density, hot-pluggable solution for data center uplinks, switch-to-switch connections and high-performance computing networks.
Advantages
The module combines high throughput with a small physical footprint, enabling dense port deployment in switch and router chassis. Its standardized QSFP28 interface ensures broad compatibility with devices supporting QSFP+ and QSFP28 cages that accept SR4 modules. Low weight and compact dimensions simplify installation and reduce strain on equipment. The 850 nm wavelength optimized for multimode fiber supports reliable short-reach transmission and low-latency operation.
Suitable for
Data center aggregation and spine-leaf architectures
High-speed switch-to-switch connections within server rooms
Short-reach links over multimode fiber (intra-building)
High-performance computing clusters and storage networks
Key specifications
Interface type: QSFP28
Maximum data transfer rate: 100000 Mbit/s
Operating wavelength: 850 nm
Form factor: QSFP28 (QSFP-4 lane SR4 optics)
Weight: 0.04 kg
How to use
Install the BlueOptics QSFP-100G-SR4-S by inserting the module into a compatible QSFP28 port until it clicks into place. Use appropriate multimode fiber patch cords (typically OM3/OM4) with MPO/MTP connectors to connect to the remote module or breakout harness. Ensure the host device supports 100 Gbit/s SR4 optics and verify link status via the switch or router management interface. For hot-pluggable operation, attach or remove the transceiver while observing the host equipment vendor's hot-swap guidelines.
Usage recommendations
Use multimode fibers rated for short-reach 100 G transmissions (OM3/OM4) and keep connectors clean to maintain signal integrity. Confirm compatibility with the host device firmware and port optics support before installation. Follow ESD precautions during handling and avoid excessive bending of fiber cables to preserve performance.
