Module transceiver QSFP28 BlueOptics 02311MNN-BO 2000 m

The BlueOptics 02311MNN-BO QSFP28 Transceiver Module is a 100GBASE-CWDM4 compatible optical transceiver designed for high-speed single‑mode fiber links up to 2000 meters. Housed in an aluminium enclosure and weighing approximately 40 grams, the module uses a QSFP28 interface with LC duplex connectivity and follows MSA guidelines for mechanical and electrical compatibility. It supports simultaneous transmit and receive channels with CWDM wavelength multiplexing and is suitable for Ethernet, Fibre Channel over Ethernet and SDH/SONET applications up to 100 Gbps.

Advantages

The module offers the physical durability of an aluminium body combined with a lightweight design for easy handling and installation. Being built to MSA-compliant specifications ensures interoperability with major network platforms that support equivalent 100GBASE-CWDM4 QSFP28 modules. Integrated digital diagnostics (DDM/DOM) provide real‑time operational parameters such as supply voltage, laser bias current, transmit output power, receive input power and temperature for simplified monitoring and troubleshooting.

Suitable for

• 100 Gbps uplinks between data center switches and aggregation devices over single‑mode fiber
• High‑speed connections for routers, storage systems and load balancers
• Metro and campus links requiring up to 2 km reach with CWDM‑based channels
• Environments needing remote diagnostics and link monitoring via DDM/DOM

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on your switch, router or other network device following the host vendor’s hot‑swap and handling guidelines. Connect an LC duplex single‑mode fiber patch cord between transceivers or to a patch panel, ensuring correct transmit/receive orientation. Verify link negotiation and operational status via the switch or device management interface and use the digital diagnostics to monitor optical parameters and temperature. Observe ESD precautions when handling optical modules and avoid bending fiber beyond the recommended radius to maintain signal integrity.

Recommendations

For optimal performance, use single‑mode LC duplex fiber patch cords and maintain clean connector endfaces. Confirm that the host hardware supports 100GBASE‑CWDM4 QSFP28 modules and DDM/DOM if remote diagnostics are required. For long‑term reliability, schedule periodic inspection of connector cleanliness and monitor DDM parameters to detect degradations early.
