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

The BlueOptics QSFP-40G-ESR4-ZY-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s data transfer over 850 nm multimode fiber. It is a compact, lightweight (0.04 kg) module that fits QSFP interfaces and provides optical transmission and reception using MPO/MTP connectivity according to MSA QSFP standards. The module supports digital diagnostics monitoring (DDM/DOM) for real-time reporting of key optical and electrical parameters and is intended for use in network devices that accept compatible QSFP transceivers.

Advantages

This QSFP transceiver offers standardized QSFP electrical and mechanical compatibility and a multimode optical interface at 850 nm, enabling interoperable operation in systems that support 40 Mbit/s QSFP optics. The module includes DDM/DOM capability for remote monitoring of supply voltage, laser bias current, optical output and input power, and temperature. With an MTBF of 1,000,000 hours and a lightweight form factor, it is designed for long-term operation and simple installation in suitable network equipment.

Suitable for

• High-speed Ethernet and fiber channel connections in switches and routers that accept QSFP modules
• Server and storage interconnects requiring multimode fiber links
• Short-range data center links using MPO/MTP multimode patching

Key specifications

• Interface type: QSFP
• Maximum data transfer rate: 40 Mbit/s
• Wavelength: 850 nm (multimode)
• Connector: MPO/MTP (MSA-compliant)
• Weight: 0.04 kg
• Digital diagnostics monitoring (DDM/DOM) supported
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the BlueOptics QSFP-40G-ESR4-ZY-BO into a compatible QSFP slot on switches, routers or other network devices while the host device is powered according to the hardware vendor's instructions. Connect multimode MPO/MTP fiber patch cords to the module and to the corresponding patch panel or transceiver at the remote end. Verify link status through the host device and, if available, read DDM/DOM values via the device management interface to confirm optical power, laser bias, voltage and temperature parameters.

Recommendations

Ensure the host hardware explicitly supports third-party QSFP transceivers and the DDM/DOM feature if remote diagnostics are required. Use appropriate multimode MPO/MTP patch cords and maintain clean fiber connections to preserve signal quality. Follow the network equipment vendor’s hot-swap and ESD handling procedures when installing or removing the module.
