BlueOptics 40G-QSFP-ESR4-INT-BO netwerk-transceivermodule glasvezel QSFP MPO MTP aluminium 40g

The BlueOptics 40G-QSFP-ESR4-INT-BO is a fiber optic network transceiver module designed for 40G high-speed data transmission. It uses a QSFP interface and an MPO/MTP connector for multi-mode fiber links, supports 850 nm transmit and receive wavelengths, and is compatible with MSA-standard QSFP ports. The module is lightweight (approximately 0.04 kg) and has an aluminium housing for reliable mechanical protection. It is intended for use in data centers and enterprise networking equipment that accept 40GBASE-ESR4 QSFP transceivers.

Advantages

The transceiver implements 40GBASE-ESR4 functionality with MPO/MTP connectivity and supports simultaneous transmit and receive over multi-mode fiber. It adheres to MSA standards for QSFP modules and includes digital diagnostic monitoring (DDM/DOM) capabilities to report parameters such as supply voltage, laser bias current, transmit power, receive power and temperature when supported by the host hardware. The aluminium housing and lightweight design simplify installation and handling in rack-mounted systems.

Suitable for

• 40 Gigabit Ethernet links in data centers
• High-speed interconnects between switches and routers
• Fibre Channel over Ethernet or SDH/SONET aggregation up to 40G
• Short to extended multi-mode fiber runs using MPO/MTP cabling

Key specifications

• Form factor: QSFP (quad small form-factor pluggable)
• Connector type: MPO/MTP
• Data rate: 40 Gbps (aggregate)
• Optical wavelength: 850 nm (Tx/Rx)
• Fiber type: Multi-mode fiber (MMF)
• Housing material/color: Aluminium
• Weight: ~0.04 kg
• Digital diagnostics: DDM/DOM support (host dependent)

How to use

Install the BlueOptics 40G-QSFP-ESR4-INT-BO by inserting the QSFP module into a compatible QSFP port on a switch, router or other networking device while the host device is powered according to the manufacturer’s instructions. Connect an MPO/MTP multi-mode fiber patch cord to the module’s MPO/MTP connector, ensuring correct polarity and secure seating of the connector. Verify link status in the host device and, if available, read DDM/DOM values through the device management interface to monitor optical parameters. Follow the host hardware vendor’s guidelines for hot-plugging and firmware compatibility.

Recommendations

Use pre-terminated MPO/MTP multimode patch cords matched to the host transceiver and the patch panel to achieve optimal range and signal quality. Ensure the receiving device supports 40GBASE-ESR4 and DDM/DOM if you plan to use diagnostic monitoring. Regularly inspect MPO/MTP connectors and clean endfaces before mating to avoid performance degradation.
