## Long description

The BlueOptics H-LR4-QSFP28-BO is a 100G fiber optic transceiver module designed for high-speed single-mode links. It uses a QSFP28 interface and LC duplex connector, is housed in a durable metal shell, and supports a maximum data rate of 100000 Mbit/s for long-reach transmission. The module is compact and lightweight (approx. 40 g) and meets CE, RoHS and FCC compliance requirements for networking deployments.
Advantages
The module supports 100GBASE-LR4 applications over single-mode fiber and implements CWDM-based transmit and receive channels for stable optical signalling. Its QSFP28 form factor enables high port density in switches and routers while the metal housing provides mechanical robustness and EMI protection. Compliance with common regulatory standards and adherence to MSA form-factor guidelines increase interoperability with compatible network equipment.
Suitable for
100G aggregation and core links in data centers
Connections between switches, routers and storage systems over single-mode fiber
Long-reach Ethernet or Fibre Channel over Ethernet links up to several kilometers
Key specifications
Interface type: QSFP28 with LC duplex optical connector
Maximum data transfer rate: 100000 Mbit/s (100 Gbit/s)
Optical medium: single-mode fiber, CWDM-based Tx/Rx
Housing: metal shell for mechanical and EMI protection
Weight: approximately 0.04 kg
How to use
Install the transceiver into a compatible QSFP28 slot on your switch, router or storage device following the host vendor’s insertion and hot-plug guidelines. Connect single-mode LC duplex patch cords to the transceiver’s LC interface, ensuring correct Tx/Rx orientation. Verify link status and speed in the host device management interface and confirm that any required DDM/DOM monitoring is enabled in the system BIOS or firmware when diagnostics are needed.
Usage recommendations
For reliable long-reach links, use high-quality single-mode fiber and LC duplex patch cords, keep optical connectors clean, and ensure that the host hardware supports 100GBASE-LR4 QSFP28 modules and DDM/DOM if monitoring is required.
