## Summary description

The BlueOptics QSFP-100G-LR4-AL is a fiber optic transceiver module designed for high-speed data transfer up to 100Gbit/s. It features a QSFP28 interface, making it suitable for data center applications and high-performance networking. This module ensures reliable connectivity and is ideal for long-range communication.

## Long description

The BlueOptics QSFP-100G-LR4-AL is a fiber optic transceiver module designed for long-range, high-speed network links. With a QSFP28 interface and support for data rates up to 100Gbit/s, this module is intended for deployment in data centers, core switches and aggregation layers where reliable 100 Gigabit Ethernet connectivity is required. The LR4 variant uses wavelength division multiplexing to transmit over single-mode fiber, providing stable performance for extended distances.
Advantages
The module supports a standardized QSFP28 form factor for compact, hot-pluggable installation in compatible ports, enabling straightforward upgrades to 100G infrastructure. It offers high throughput at 100Gbit/s while maintaining low power consumption and a small footprint. Built for single-mode fiber long-reach links, the transceiver provides consistent signal integrity and interoperability with systems that follow common optical specifications.
Suitable for
 Data center uplinks and spine-to-leaf connections
 Carrier and metro long-distance 100G links over single-mode fiber
 High-performance switch and router interfaces requiring QSFP28 modules
 Network equipment upgrades from 10G/40G to 100G infrastructure
Key specifications
 Interface type: QSFP28
 Maximum data transfer rate: 100000 Mbit/s (100 Gbit/s)
 Optical type: single-mode fiber, LR4 wavelength multiplexing
 Form factor: QSFP28, hot-pluggable
 Typical use: long-range 100 Gigabit Ethernet links
How to use
Insert the transceiver into a compatible QSFP28 port on a switch or router while the host port is powered and follow the device manufacturer's hot-plug recommendations. Connect the single-mode fiber patch cables using appropriate MPO/MTP or LC breakout connections as required by the LR4 interface and ensure correct polarity and cleaning of fiber endfaces. Verify link status and speed through the network device management interface and monitor for alarms or signal degradation after installation.
Usage recommendations
Use certified single-mode fiber and follow optical power budget calculations appropriate for LR4 links. Keep fiber connectors clean, avoid excessive bending of fiber cables, and test the link with appropriate optical diagnostic tools after installation. Confirm compatibility with the host equipment's transceiver support list before deployment.
