QSFP transceiver modul BlueOptics QSFP-40G-ESR4-SS-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-ESR4-SS-BO is a QSFP fiber optic transceiver module designed for 40 Gigabit Ethernet links over multimode fiber. It operates at 850 nm with a maximum data transfer rate of 40 Mbit/s and supports a maximum transfer distance of up to 300 m using an MTP/MPO connector. The module is lightweight (approximately 0.04 kg) and specifies an MTBF of 1,000,000 hours for reliable continuous operation in network equipment that accepts QSFP form-factor optics.

Advantages

The module provides a compact QSFP interface compatible with 40 Gigabit Ethernet deployments and uses MTP/MPO connectivity for parallel multimode fiber links. With a specified MTBF of 1,000,000 hours and a weight of just 40 g, it is easy to handle and integrate into switches, routers or other optical network hardware. The transceiver supports simultaneous transmit and receive operation on the defined wavelength, enabling point-to-point high-speed multimode links up to the stated distance.

Suitable for

• 40 Gigabit Ethernet uplinks and aggregation links
• Data center short-range multimode fiber connections (up to 300 m)
• High-density switch and router QSFP ports requiring MTP/MPO connectivity
• Network installations needing compact, low-weight transceiver modules

How to use

Install the transceiver into a compatible QSFP port on switch, router or other network hardware following the host vendor's insertion and hot-swap procedures. Connect an appropriate multimode MTP/MPO patch cord to the module and route the other end to the corresponding MTP/MPO port or patch panel. Verify link status and speed on the host device; ensure the host platform supports QSFP modules at the specified wavelength and data rate. Observe ESD precautions and handle the optical interfaces with protective caps when not connected.

Recommendations

Use high-quality multimode MTP/MPO patch cords and ensure fiber polarity and MPO cassette wiring match the link requirements. Confirm that the network equipment supports this QSFP module and that any digital diagnostic features are supported by the host for monitoring supply voltage, temperature and optical power if required.
