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

The BlueOptics QSFP-40G-ESR4-PT-BO is a QSFP transceiver module designed for multimode fiber links and high-speed networking. It supports a maximum data transfer rate of 40 Mbit/s at an operating wavelength of 850 nm, uses an MTP/MPO fiber connector and is specified for link distances up to 300 m. With a lightweight 40 g housing and an MTBF of 1,000,000 hours, the module is intended for installation in compatible 40 Gigabit Ethernet ports where MSA-compliant QSFP modules are supported.

Advantages

The transceiver provides a compact, MSA-compliant form factor that facilitates interoperability with hardware that accepts QSFP modules and MPO/MTP connections. It integrates receive and transmit functions at 850 nm for multimode deployments and offers a low-weight design for easy handling and installation. The module's long MTBF value indicates extended operational life, which supports reduced maintenance cycles and predictable replacement planning in network environments.

Suitable for (tasks / use cases)

• 40 Gigabit Ethernet uplinks and aggregation links in data centers
• High-speed connections between switches, routers and storage systems over multimode fiber
• Short- to medium-range fiber backbones up to 300 m
• Environments requiring MPO/MTP multi-fiber connectivity

• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the QSFP-40G-ESR4-PT-BO into a compatible QSFP slot following the host system vendor's hot-plug guidance. Connect a suitable MPO/MTP multimode patch cable to the module and route the other end to the matching MPO/MTP port or patch panel. Ensure the host device supports QSFP modules and the required 40 Gigabit Ethernet protocol. If supported by the hardware, enable and monitor the module's digital diagnostic (DDM/DOM) features via the host management interface to check supply voltage, laser bias, optical power levels and temperature for ongoing link health verification.

Recommendations

Use high-quality multimode MPO/MTP patch cords and maintain proper fiber handling to preserve optical performance. Verify host compatibility with MSA-compliant QSFP modules and confirm any required firmware or software settings for 40G operation. For reliable operation over the specified distance, choose multimode fiber with appropriate attenuation and follow recommended link design practices.
