QSFP-lähetin-vastaanotinmoduuli BlueOptics QSFP-40G-ESR4-NK-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-NK-BO is a fiber optic QSFP transceiver module designed for 40 Gigabit Ethernet links over multimode fiber. It supports a maximum data transfer rate of 40 Mbit/s and operates at an 850 nm wavelength. The module uses an MTP/MPO fiber connector and is lightweight at approximately 40 g. With a specified mean time between failures (MTBF) of 1,000,000 hours, the transceiver is intended for continuous network use where long service life and interoperability with MSA-compliant QSFP ports are required.

Advantages

The transceiver combines multimode 850 nm optical transmission with an MPO/MTP connector to support parallel optical links. Its compact QSFP form factor and 40 Gigabit Ethernet interface type allow integration into standard QSFP-capable switches, routers and other networking equipment that accept MSA-compliant modules. A high MTBF rating and low weight make the module suitable for dense deployments with minimal impact on rack space and handling.

Suitable for

• 40 Gigabit Ethernet connections over multimode fiber
• Data center aggregation and spine-leaf topologies
• High-speed links between switches, routers and storage systems
• Environments requiring MTP/MPO connectorized parallel optics

Key specifications

• Maximum data transfer rate: 40 Mbit/s
• Wavelength: 850 nm
• Interface type: 40 Gigabit Ethernet (QSFP form factor)
• Fiber connector: MTP/MPO (parallel multimode fiber)
• Weight: 0.04 kg
• Mean Time Between Failures (MTBF): 1,000,000 hours

How to use

Install the QSFP transceiver into a compatible QSFP slot on a supported switch, router or other networking device following the vendor’s hot-plug and handling guidelines. Connect an MTP/MPO-terminated multimode fiber patch cord to the transceiver, ensuring correct alignment of the connector and that the link uses appropriate cabling and polarity for parallel optical lanes. Verify link status and speed on the host hardware and, if available, enable digital diagnostics monitoring in the management interface to observe supply voltage, optical power and temperature metrics supported by the device.

Recommendations

Use industry-standard multimode fiber and MPO/MTP patch cords rated for the intended distance and bandwidth. Confirm hardware compatibility with the host device and ensure network firmware supports QSFP modules and any available diagnostic functions. Handle the transceiver by its housing, keep connector endfaces clean, and follow ESD precautions during installation and removal.
