## Summary description

The BlueOptics 100G-LR4-QSFP2KM-BO is a fiber optic network transceiver module designed for high-speed data transfer with a maximum rate of 100000 Mbit/s. It features a QSFP28 interface and a compact form factor, ensuring efficient performance in data centers and networking applications. With a mean time between failures (MTBF) of 1000000 hours, it offers reliability and longevity for critical network infrastructures.

## Long description

The BlueOptics 100G-LR4-QSFP2KM-BO network transceiver module is a fiber optic QSFP28 device engineered for 100000 Mbit/s links in data center and enterprise networks. Its compact QSFP28 form factor and silver housing support high-density port deployment while maintaining compatibility with equipment accepting QSFP28 interfaces. The module is specified for long-reach single-mode fiber operation and provides an MTBF of 1,000,000 hours to support continuous operation in critical infrastructure.
Advantages
The QSFP28 interface provides four 25 Gbit/s lanes aggregated to 100 Gbit/s throughput, allowing migration paths from 10/25 Gbit/s architectures to 100 Gbit/s. The small, lightweight silver module reduces space and thermal load in populated switch or router ports. High MTBF indicates lower expected failure rates and supports predictable maintenance planning. The design is suitable for hot-plug installation and straightforward replacement without network downtime when used according to vendor guidelines.
Suitable for
 100 Gbit/s uplinks between switches in data centers
 Long-reach single-mode fiber links up to certified distances for LR4 optics
 High-density aggregation in enterprise and carrier networks
 Hardware refresh and capacity upgrades in optical transport systems

How to use
Install the BlueOptics QSFP28 transceiver into a compatible QSFP28 port on your switch or router while the host device is powered according to the equipment vendor's instructions for hot-plug modules. Connect single-mode fiber optic cables with appropriate LC or MPO/MTP breakout assemblies as required by LR4 optics and ensure correct fiber polarity. Verify link state and transceiver recognition through the host device management interface. Follow standard electrostatic discharge (ESD) precautions when handling the module and keep dust caps on unused ports until connection.
Usage recommendations
Use the module in environments within the host equipment's specified temperature and humidity ranges and pair it with compatible single-mode fiber cabling and optical connectors. For optimal performance, verify firmware and driver compatibility of the network device and perform link tests after installation to confirm expected throughput and signal quality.
