Fiber optic transceiver module BlueOptics ET7402-PSM4-2-BO QSFP28 MTP/MPO

The BlueOptics ET7402-PSM4-2-BO QSFP28 MTP/MPO is a fiber optic transceiver module engineered for 100G high-speed data transmission over single-mode fiber. The module uses a QSFP28 interface with an MTP/MPO connector and is housed in an aluminium enclosure weighing approximately 40 g. Designed according to MSA standards, it supports simultaneous transmit and receive channels and is compatible with systems that accept 100GBASE-PSM4 QSFP28 transceivers.

Advantages

The transceiver provides a compact QSFP28 form factor for high-density installations and uses single-mode optical transmission to enable long-reach links. Its aluminium housing offers mechanical durability while keeping weight low. Conformance to MSA standards and use of MTP/MPO connectivity simplify integration into existing optical infrastructures. Where supported by host hardware, the module provides digital diagnostic monitoring for real-time status of parameters such as supply voltage, laser bias current, optical output/input power and temperature.

Suitable for

• 100G Ethernet aggregation and spine links in data centers
• High-speed interconnects between switches, routers and storage systems
• Fiber backbone connections over single-mode fiber
• Environments requiring MPO/MTP cabling and QSFP28 modularity

Key specifications

• Interface type: QSFP28
• Connector type: MTP/MPO
• Optical medium: single-mode fiber
• Supported standard: 100GBASE-PSM4 (optical 100 Gbps)
• Housing material: aluminium (product colour: aluminium)
• Weight: ~0.04 kg
• Digital diagnostics: supported when host hardware provides DDM/DOM access

How to use

Install the BlueOptics ET7402-PSM4-2-BO into a compatible QSFP28 slot on your switch, router or other networking equipment that supports 100GBASE-PSM4 modules. Connect an appropriate MTP/MPO single-mode patch cord between the module and the matching patch panel or transceiver at the remote end, ensuring proper polarity and fiber alignment. Confirm that the host device firmware supports third‑party transceivers and, if required, enable digital diagnostic monitoring via the host management interface to read real-time module parameters.

Usage recommendations

Use factory‑terminated single-mode MTP/MPO patch cords and, where possible, route fibers via patch panels to protect connectors. Verify DDM/DOM availability in the host system before relying on diagnostic data. Ensure cleanliness of MPO/MTP ferrules and follow standard fiber handling procedures to maintain link performance and lifetime.
