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

The BlueOptics QSFP-40G-ESR4-NG-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s high-speed links over multimode fiber. It uses an 850 nm wavelength and an MTP/MPO connector to support parallel optical lanes. The module is lightweight (approx. 40 g) and is specified with a mean time between failures (MTBF) of 1,000,000 hours, providing a component option for 40 Gigabit Ethernet ports and similar high-speed networking equipment.

Advantages

This QSFP transceiver follows MSA-compliant mechanical and electrical specifications for interoperable use in a range of systems and features MPO/MTP connectivity for parallel multimode links. It supports simultaneous transmit and receive operation on optical lanes at 850 nm and is tested for compatibility with major hardware platforms that accept equivalent 40GBASE-ESR4 QSFP modules. The design emphasizes long operational lifetime, compact form factor, and support for digital diagnostics where supported by host hardware.

Suitable for

• 40 Gigabit Ethernet uplinks and switch interconnects in data centers
• High-speed storage area networks and server aggregation
• Short-reach multimode fiber connections up to 300 m
• Environments requiring MPO/MTP trunking or parallel optics

Key specifications

• Maximum data transfer rate: 40 Mbit/s
• Wavelength: 850 nm
• Maximum transfer distance over multimode fiber: 300 m
• Interface type: QSFP (40 Gigabit Ethernet)
• Fiber connector: MTP/MPO
• Weight: approximately 0.04 kg
• Diagnostic capability: Digital Diagnostics Monitoring (DDM/DOM) when supported by host
• MSA-compliant form factor for interoperability

How to use

Install the QSFP module into a compatible QSFP port on a switch, router or other networking device that supports 40GBASE-ESR4 optics. Connect an appropriate MPO/MTP multimode fiber cable or patch cord between transceivers or to a compatible patch panel. Ensure the host device firmware and configuration allow use of third-party MSA-compliant modules and enable digital diagnostics if available. Observe ESD precautions and follow manufacturer guidance for insertion/removal to avoid damage to fiber endfaces and the transceiver.

Recommendations

For best performance, use high-quality OM3/OM4 multimode fiber and MPO/MTP cabling rated for 40G parallel optics, verify link support in the host hardware, and keep fiber connectors clean. If digital diagnostics are required, confirm the host supports DDM/DOM to monitor supply voltage, laser bias current, transmit/receive power and temperature in real time.
