Fiber optic transceiver module BlueOptics 100GQSFP-LR4-4= with QSFP28 interface

The BlueOptics 100GQSFP-LR4-4= is a 100GBASE-LR4 QSFP28 fiber optic transceiver module with a QSFP28 interface and LC Duplex connector. Designed for single-mode fiber links, it supports reliable high-speed data transmission up to 10,000 m. The module is built in an aluminium housing, weighs approximately 40 g and implements MSA-compliant electrical and optical interfaces for compatibility with major network equipment that supports 100GBASE-LR4 QSFP28 transceivers.

Advantages

The transceiver provides 100 Gbit/s transmission over long-reach single-mode fiber using CWDM channels and supports Ethernet, Fibre Channel over Ethernet and SDH/SONET protocols. It is compatible with a wide range of hardware platforms that accept 100GBASE-LR4 QSFP28 modules, and includes Digital Diagnostics Monitoring (DDM/DOM) compliant with MSA SFF-8472 for real-time monitoring of voltage, bias current, temperature and optical power. The aluminium housing and selected high-quality optical and electronic components contribute to long operational life and stable performance.

Suitable for

• Data centre uplinks and spine-leaf architectures
• High-performance campus and metro fiber links up to 10 km
• Switches, routers, storage systems and load balancers requiring 100GBASE-LR4 QSFP28
• High-bandwidth applications such as virtualization, storage replication and aggregation

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port on supported network hardware following the vendor’s hot-plugging guidelines. Connect LC Duplex single-mode fiber patch cords to the module’s LC receptacles, ensuring correct transmit/receive polarity. Verify link status in the host device and, if available, enable or query DDM/DOM to monitor optical power, temperature and supply voltage. Ensure that the connected device firmware and software support third-party or compatible 100GBASE-LR4 QSFP28 modules when required by the vendor.

Usage recommendations

Use single-mode LC Duplex patch cords of appropriate quality and route fibers to avoid sharp bends. Confirm compatibility with the target hardware platform and enable DDM/DOM monitoring where supported to assist with troubleshooting and preventive maintenance. Store and handle the module in clean, ESD-safe conditions and observe manufacturer instructions for insertion and removal to maintain connector and transceiver integrity.
