Network transceiver module BlueOptics MA-QSFP-40G-SR4-BO Fiber optic QSFP MTP/MPO

The BlueOptics MA-QSFP-40G-SR4-BO is a 40GBASE-SR4 fiber optic QSFP transceiver module with an MTP/MPO connector designed for high-speed multimode fiber networks. It uses a QSFP interface to provide up to 40 Gbps aggregated bandwidth over multiple lanes and is supplied in a lightweight aluminium housing weighing 0.02 kg. The module is suitable for short-reach data center links and networking equipment that accept QSFP transceivers with MTP/MPO multimode connections.

Advantages

The transceiver follows MSA-compatible QSFP form-factor standards and supports simultaneous transmit and receive operation over multimode fibers using 850 nm optics. Its compact aluminium enclosure and 20 g weight simplify handling and installation in dense switch or router linecards. Designed and tested for interoperability, the module provides digital diagnostic monitoring (DDM/DOM) support when the host hardware exposes that functionality, enabling real-time monitoring of optical parameters for maintenance and troubleshooting.

Suitable for

• Short-reach 40 Gbps links in data centers
• High-density switch-to-switch and switch-to-server connectivity
• Multimode fiber backbone and patch-panel connections with MPO/MTP cabling

Key specifications

• Interface type: QSFP
• Connector: MTP/MPO multimode fiber connector
• Optical wavelength: 850 nm (multimode operation)
• Maximum aggregated data rate: 40 Gbps
• Typical reach: short-range multimode links (up to the multimode fiber specification limits)
• Housing colour/material: aluminium
• Weight: 0.02 kg
• Digital diagnostic monitoring (DDM/DOM): supported when host hardware provides support

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch, router or other network device following the device manufacturer’s hot-plug procedure. Connect an MPO/MTP multimode fiber patch cord to the transceiver connector and route the cable to the mating MPO/MTP connector or patch panel. Verify link status on the host device and, if available, read DDM/DOM parameters from the management interface to confirm optical power and operating conditions.

Recommendations

Use high-quality multimode MPO/MTP patch cords and ensure fiber polarity and breakout arrangements match your switch/router configuration. Confirm that the host hardware supports 40GBASE-SR4 QSFP transceivers and DDM if remote diagnostics are required. Follow ESD handling guidelines during installation and maintain clean connector endfaces to ensure optimal optical performance.
