BlueOptics QSFP-100GBASE-LR4 network transceiver module 100000 Mbit/s QSFP28

The BlueOptics QSFP-100GBASE-LR4 network transceiver module is a compact fiber-optic module designed for 100 Gbit/s long-reach connections. With a QSFP28 interface and a silver metal housing weighing just 20 g, this module supports high-speed data transmission over single-mode fiber for extended distances. It is engineered for integration into switches, routers and optical equipment that accept QSFP28 form-factor modules and is intended for data center and enterprise network environments that require reliable 100G links.

Advantages

The module provides a standardized QSFP28 interface for straightforward installation and hot-pluggable replacement. Its 100000 Mbit/s capacity enables aggregation of high-throughput traffic while preserving port density. The lightweight metal housing improves thermal performance and mechanical stability, and the long-reach optical design reduces the need for intermediate active devices on links between buildings or within campus networks.

Suitable for

• 100G uplinks between core switches in data centers
• Long-distance single-mode fiber connections within campuses or between sites
• High-throughput aggregation links for enterprise networks
• Optical equipment requiring QSFP28 form-factor transceivers

How to use

Install the BlueOptics QSFP-100GBASE-LR4 module into a QSFP28-compatible port on a switch or router while the device is powered according to the host equipment manual. Connect single-mode fiber LC duplex or MTP/MPO infrastructure as required by the host and fiber type; verify polarity and connector type match. After installation, monitor link status and signal parameters through the host equipment to confirm the module is operating at the expected 100 Gbit/s rate.

Recommendations

Ensure compatibility with the host device before installation and use appropriate single-mode fiber and connectors rated for long-reach 100G transmission. Maintain clean fiber connectors and observe manufacturer guidelines for electrostatic discharge (ESD) handling and ambient operating conditions to preserve optical performance and module longevity.
