QSFP Transceiver Module BlueOptics QSFP-100G-LR4-D-BO Fiber Optic QSFP28

The BlueOptics QSFP-100G-LR4-D-BO is a QSFP28 fiber optic transceiver module designed for 100G high-speed data transmission over single‑mode fiber. It uses an LC duplex connector and follows MSA-compatible QSFP28 interface standards, providing long‑reach 100GBASE‑LR4 connectivity for data centers, enterprise networks and carrier links. The module is lightweight (0.04 kg) with an aluminium housing and supports simultaneous transmit and receive channels with CWDM wavelengths for distance transmission up to 10 kilometres when used with appropriate single‑mode fiber.

Advantages

The module implements 100GBASE‑LR4 optical signalling and is compatible with platforms that support the original LR4 QSFP28 transceivers. It includes both transmitter and receiver sections with CWDM channels, supports Digital Diagnostic Monitoring (DDM/DOM) for real‑time monitoring of supply voltage, laser bias current, optical output/input power and temperature, and is manufactured to MSA mechanical and electrical specifications. Components are selected to meet industry quality standards for extended operational lifetime and high mean time between failures.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on your switch, router or optical device while the host is powered according to the platform vendor guidelines. Connect the LC duplex single‑mode patch cord to the module and to the remote transceiver or patch panel. Ensure correct orientation and secure latching of the LC connector to avoid signal loss. Verify link negotiation and SFP/QSFP support in the device firmware so that the host recognizes the module and enables the DDM/DOM interface if supported.

Recommendations

Use single‑mode fiber certified for long‑reach applications and maintain clean connectors and patch cords to ensure optimal optical performance. Confirm hardware compatibility and firmware support for third‑party QSFP28 LR4 modules on your platform before deployment, and use DDM/DOM readings to monitor link health and to assist with troubleshooting.
