QSFP Transceiver Module BlueOptics QSFP-40G-ESR4-CP-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-CP-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s optical links. It operates at an 850 nm wavelength over multimode fiber and uses an MTP/MPO connector for parallel fiber connections. The module supports up to 300 m transmission distance, fits 40 Gigabit Ethernet interfaces and is lightweight at approximately 0.04 kg. Its documented mean time between failures (MTBF) of 1,000,000 hours indicates suitability for continuous operation in network environments that require stable, long-lived optics.

Advantages

The transceiver provides QSFP form-factor compatibility for systems that accept 40 Gigabit Ethernet optics and uses standardized MSA mechanical and electrical interfaces to promote interoperability. With support for an 850 nm transmitter and receiver and MPO/MTP connectivity, the module enables parallel multimode links for high-throughput short-reach applications. The product’s low weight and compact QSFP package make it easy to install into compatible switch, router, or storage hardware. The listed MTBF reflects a design emphasis on reliability and reduced maintenance intervals.

Suitable for

• Short-reach multimode fiber links within data centers (up to 300 m)
• 40 Gigabit Ethernet uplinks and aggregation ports
• Interconnection between switches, routers and storage arrays that accept QSFP optics

How to use

Install the QSFP-40G-ESR4-CP-BO into a compatible QSFP slot on a switch, router or other network device that supports 40 Gigabit Ethernet optics. Ensure the host device supports the module’s digital diagnostic and MSA-compatible QSFP interface if you plan to use monitoring features. Connect an appropriate MPO/MTP multimode patch cord between transceivers or to a patch panel, observing proper fiber handling and bend radius guidelines. Verify link status and negotiated speed on the host device after installation.

Recommendations

Use multimode fiber rated for the intended distance and verify that connected hardware officially supports QSFP optics for 40 Gigabit Ethernet. If digital diagnostics are required for remote monitoring, confirm that the host platform exposes the DDM/DOM data. Handle the MPO/MTP connector with dust caps installed until mating and follow standard ESD precautions during installation.
