## Summary description

The BlueOptics TN-QSFP-100G-LR4-BO is a fiber optic transceiver module designed for high-speed data transfer with a maximum rate of 100000 Mbit/s. It features a QSFP28 interface and is lightweight at 40 g, making it suitable for various networking applications. This module is ideal for enhancing network performance and ensuring reliable connectivity.

## Long description

The BlueOptics TN-QSFP-100G-LR4-BO is a fiber optic transceiver module designed for high-speed data transmission at up to 100000 Mbit/s. It implements a QSFP28 interface in a compact, lightweight metal housing with a silver finish and uses LC duplex connectors for single-mode fiber links. The module supports long-reach optical connections and is intended for integration into networking hardware that accepts QSFP28 100GBASE-LR4 transceivers.
Advantages
This QSFP28 transceiver provides a standardized mechanical and electrical interface for 100G optical links, enabling simultaneous send and receive operations over LC duplex single-mode fiber. The lightweight design (approx. 40 g) and compliance with MSA-compatible QSFP28 form factor simplify installation and replacement. Built to support long-reach connections, the module reduces susceptibility to electromagnetic interference inherent to copper links and enables stable high-bandwidth transmission for demanding network environments.
Suitable for
 100G Ethernet uplinks between switches and routers
 Data center interconnects and aggregation links
 High-performance storage networks and server connections
 Long-reach single-mode fiber links up to the module's supported distance
Key specifications
 Interface type: QSFP28
 Maximum data transfer rate: 100000 Mbit/s (100 Gbps)
 Optical connector: LC duplex (single-mode fiber)
 Application: 100GBASE-LR4 optical transmission
 Product colour: Silver
 Weight: approximately 0.04 kg
How to use
Insert the BlueOptics QSFP28 transceiver into a compatible QSFP28 port on a switch, router or other networking equipment while following the host manufacturer's hot-plugging guidelines. Connect LC duplex single-mode fiber patch cords to the transceiver's connectors, ensuring correct transmit/receive orientation. Verify link status and speed through the host device management interface. If supported by the host, enable or query Digital Diagnostics Monitoring (DDM/DOM) to monitor supply voltage, laser bias current, output power, received power and module temperature in real time.
Usage recommendations
Ensure host hardware explicitly supports 100GBASE-LR4 QSFP28 modules and that firmware does not restrict third-party transceivers. Use quality single-mode LC duplex patch cords and proper fiber management to achieve optimal range and signal integrity. If monitoring is required, confirm DDM/DOM compatibility in the host to access diagnostic parameters for maintenance and troubleshooting.
