Product information

Description

The BlueOptics QSFP-40G-ESR4-MR-BO is a 40 Gigabit Ethernet QSFP transceiver module designed for multimode fiber systems. Featuring an MTP/MPO connector and a lightweight aluminium housing, this module supports 40GBASE-ESR4 links up to 300 m and provides simultaneous transmit and receive channels using 850 nm optics. The module is suitable for data center uplinks, aggregation links and other high-speed fiber runs where compact QSFP form-factor and MTP/MPO connectivity are required.

Advantages

This QSFP transceiver offers compatibility with hardware platforms that support 40GBASE-ESR4 optics, tested to MSA standards. The MTP/MPO connector enables parallel multimode connections and simplified cabling for high-density environments. With a small 40 g weight and aluminium color housing, the module is easy to install and integrates cleanly into switch and router ports. Support for digital diagnostics (DDM/DOM) allows remote monitoring of voltage, temperature, laser bias and optical power for easier maintenance and fault analysis.

Suitable for

  • Data center server-to-switch uplinks and spine/leaf aggregation
  • High-speed multimode fiber links within enterprise networks
  • Switches, routers and storage systems that accept 40G QSFP modules
  • Environments requiring MTP/MPO parallel optical connections

Key specifications

  • Interface type: 40 Gigabit Ethernet (QSFP)
  • Optical standard: 40GBASE-ESR4
  • Wavelength: 850 nm transmit and receive
  • Connector: MTP/MPO
  • Maximum transfer distance: up to 300 m over multimode fiber
  • Housing colour: aluminium
  • Weight: 0.04 kg
  • Digital diagnostics monitoring: supported (DDM/DOM)

How to use

Insert the BlueOptics QSFP-40G-ESR4-MR-BO into a compatible QSFP port following the host device manufacturer’s hot-swap and handling instructions. Use appropriate MTP/MPO multimode patch cords and verify fiber polarity and connector cleanliness before insertion. After installation, confirm the link status on the host device and, if available, enable DDM/DOM to monitor real-time parameters such as temperature and optical power. Ensure the host platform supports 40GBASE-ESR4 optics to guarantee interoperability.

Usage recommendations

For optimal performance, pair the transceiver with OM3/OM4 multimode fiber and MTP/MPO patch cords rated for 40G parallel links, keep connectors clean using approved cleaning tools, and verify compatibility with the target switch or router model. Use the DDM/DOM interface for proactive monitoring and troubleshooting.

Specifications

Maximum transfer distance: The greatest distance over which the data/signal can be transferred.
300 m
Fiber optic connector: This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.
