QSFP-lähetin-vastaanotinmoduuli BlueOptics QSFP-40G-ESR4-MR-BO kuitu

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

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.

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.
