QSFP Transceiver Module BlueOptics QSFP-100G-4WDM40-I-BO 100G 40g

The BlueOptics QSFP-100G-4WDM40-I-BO is a compact QSFP28 fiber optic transceiver module engineered for 100G data transmission over single-mode fiber. Featuring an LC duplex connector and a QSFP28 interface, this module supports long-reach links up to 40,000 meters while maintaining a lightweight, aluminium housing of approximately 40 g. It implements 4-wavelength CWDM channels (4WDM) for 100GBASE-ER4 applications and uses industry MSA-compliant form factor and optical interfaces for broad interoperability with compatible network equipment.

Advantages

The module provides high-speed 100G connectivity with support for extended reach, making it suitable for data center interconnects and metro links. Built to MSA standards, it offers compatibility across a range of QSFP28-capable switches, routers and storage systems. The LC duplex connector and single-mode fiber operation reduce susceptibility to electromagnetic interference and deliver stable optical transmission. Its small, lightweight aluminium design simplifies handling and installation in dense equipment bays.

How to use

Install the QSFP-100G-4WDM40-I-BO into any compatible QSFP28 port following the host device vendor instructions. Connect an appropriate single-mode LC duplex patch cable between this transceiver and the remote transceiver or patch panel. Ensure the connected equipment is configured for 100G operation and supports the 100GBASE-ER4 optical standard and CWDM wavelengths. Verify link status and, if applicable, enable digital diagnostics monitoring (DDM/DOM) through the host system to monitor supply voltage, laser bias/current, optical transmit/receive power and temperature.

Recommendations

Use single-mode LC patch cords and adhere to manufacturer guidelines for ESD protection and cleanliness of connectors. Confirm host compatibility with QSFP28 100GBASE-ER4 modules and enable DDM/DOM on supported platforms to aid remote diagnostics and link monitoring.
