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

The BlueOptics QSFP-40G-ESR4-VA-BO is a QSFP fiber optic 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 a wavelength of 850 nm. The module uses an MTP/MPO fiber connector, is specified for link distances up to 300 m, and has an MTBF of 1,000,000 hours. The compact pluggable form factor and a weight of 40 g make this transceiver suitable for integration into switches, routers and other high-density network equipment that accept QSFP modules.

Advantages

The transceiver follows QSFP form-factor conventions and MSA-aligned connector standards to provide electrical and mechanical interoperability in compatible systems. Built for multimode fiber transmission at 850 nm, it supports simultaneous transmit and receive operation through an MPO/MTP interface. High MTBF and a lightweight design contribute to reliable, low-maintenance operation in data center and enterprise networking environments.

Suitable for

• 40 Gigabit Ethernet uplinks and inter-switch connections over multimode fiber

How to use

Install the QSFP transceiver into a compatible QSFP port on network equipment according to the host vendor's instructions, ensuring the device supports the specified QSFP module type. Connect an appropriate MPO/MTP multimode fiber patch cord to the module and route it to the corresponding transceiver or patch panel. Power up the equipment and verify link light and interface status in the host system. If the host platform supports digital diagnostics, monitor module parameters via the management interface as available.

Recommendations

Use OM3/OM4 multimode fiber and certified MPO/MTP patch cords to achieve the specified up-to-300 m reach. Verify compatibility with the host hardware and enable any required firmware or software support for QSFP modules before deployment to ensure proper operation and access to diagnostic information.
