Product information

Description

The BlueOptics QSFP-40G-ESR4-DE-BO is a QSFP form-factor transceiver module engineered for 40 Gbit/s optical data transmission over multimode fiber at an 850 nm wavelength. Designed to meet MSA-compatible QSFP interfaces, this silver-coloured module is lightweight (approximately 40 g) and intended for use in common network hardware that accepts QSFP transceivers. With a high MTBF rating, the module targets long service life and stable operation in data centre and enterprise environments.

Advantages

The module supports 40 Gbit/s line rates and uses standardized QSFP connectivity to simplify integration into switches, routers and other networking platforms. It is produced to MSA standards and is tested for compatibility with relevant vendor platforms, ensuring interoperability when used with matching MPO/MTP multimode cabling. Integrated digital diagnostic monitoring (DDM/DOM) enables real-time monitoring of key optical and electrical parameters. The construction uses proven optical and electronic components to deliver extended operating life and reduced maintenance frequency.

Suitable for

  • 40 Gigabit aggregation links in data centres and campus networks
  • High-capacity switch-to-switch or switch-to-direct-attach transceivers
  • Upgrading network uplinks and stacking connections that accept QSFP modules
  • Environments requiring DDM/DOM monitoring for link diagnostics

Key specifications

  • Form factor: QSFP
  • Maximum data transfer rate: 40,000 Mbit/s (40 Gbit/s)
  • Operating wavelength: 850 nm
  • Cable interface: MPO/MTP multimode fiber (compliant with MPO/MTP connections)
  • Colour: Silver
  • Weight: approximately 0.04 kg
  • Digital Diagnostic Monitoring (DDM/DOM): supported (MSA SFF-8472 compliant)
  • Intended for use with standard 40GBASE-ESR4 optical links

How to use

Install the QSFP transceiver into a compatible QSFP port on the target switch, router or other network equipment following the host vendor’s hot-plug instructions. Use MPO/MTP multimode fiber patch cables that match the module’s MPO/MTP connector and the supported multimode fibre type. Verify link status via the host device and, if available, monitor DDM/DOM values through the management interface to confirm correct optical power levels and operating temperature. When removing the transceiver, follow the device vendor’s guidance to avoid electrostatic discharge and mechanical damage.

Usage recommendations

For reliable performance, pair the module with MPO/MTP multimode patch cables and QSFP-compatible ports that support 40GBASE-ESR4. Ensure the host device firmware supports third-party QSFP modules and DDM/DOM reporting if remote diagnostics are required. Maintain clean fiber connectors and observe proper insertion/removal procedures to extend service life.
