## Summary description

The BlueOptics R4G20A-BO is a fiber optic transceiver module designed for high-speed data transfer at 100 Mbit/s. It features a QSFP28 interface and is made of durable aluminum, weighing 40 g. This module is ideal for networking applications requiring reliable and efficient data transmission.

## Long description

The BlueOptics R4G20A-BO fiber optic transceiver module provides optical connectivity via a QSFP28 interface for network environments that require reliable, single-mode fiber transmission. Engineered in an aluminium housing and weighing approximately 40 g, this module supports a maximum data transfer rate of 100 Mbit/s and is intended for integration into compatible networking hardware that accepts QSFP28 transceivers.
Advantages
The transceiver is constructed with a durable aluminium enclosure for stable mechanical performance and reduced thermal sensitivity. Its QSFP28 interface offers a standardized physical connection for modular installation. The module’s single-mode fiber design supports simultaneous transmit and receive optical channels through duplex connectors, enabling point-to-point optical links with predictable performance. Lightweight design facilitates handling and installation in dense rack environments.
Suitable for
Point-to-point single-mode fiber links
Switches, routers and other QSFP28-compatible networking devices
Data center interconnects and uplinks
Environments requiring a compact, metal-encased transceiver
Key specifications

How to use
Install the BlueOptics R4G20A-BO into a compatible QSFP28 port following the host device manufacturer’s hot-plug or power-off procedures. Connect the LC duplex single-mode fiber patch cord to the module’s optical interface, observing transmit/receive orientation. Configure the host network device as required for the intended link speed and protocol. Ensure physical connectors are clean and that cable routing avoids excessive bend radius to maintain optical performance.
Usage recommendations
Verify host compatibility with QSFP28 modules and confirm support for the intended data rate and optical standards before deployment. Use certified single-mode LC duplex patch cords and keep connectors clean. If your platform supports digital diagnostics, enable diagnostics monitoring to observe parameters such as optical power and module temperature for proactive maintenance.
