## Long description

The BlueOptics E40GQSFPSR-BO is a fiber optic transceiver module designed for 40 Gbit/s optical links. It uses a QSFP interface and operates at an 850 nm wavelength for multimode fiber connections. Compact and lightweight at approximately 20 g, the module is built to meet RoHS requirements and is intended for use in data center and enterprise network equipment that supports QSFP 40G optics.
Advantages
The module delivers a 40000 Mbit/s maximum data transfer rate over multimode fiber using an 850 nm transmitter and receiver. Its QSFP form factor provides high port density and hot-pluggable convenience for switch and router ports. The transceiver’s silver housing and low weight simplify handling and installation. Compliance with RoHS and common industrial standards ensures environmental and regulatory compatibility.
Suitable for
Short-reach 40G Ethernet links in data centers
High-speed interconnects between switches and routers
Server-to-switch uplinks and aggregation ports
Multimode fiber installations requiring QSFP modules
Key specifications
Interface type: QSFP
Maximum data transfer rate: 40000 Mbit/s
Operating wavelength: 850 nm
Weight: 0.02 kg
Product colour: Silver
How to use
Insert the QSFP transceiver into a compatible QSFP port on a switch, router, or other network device while the host port is powered and supported by the device firmware. Connect an appropriate MPO/MTP-compatible multimode fiber cable to the module’s optical interface, ensuring correct polarity and connector seating. Verify link status through the host device management interface and, if available, use digital diagnostics monitoring features provided by the system to check optical parameters and health.
Usage recommendations
Use multimode fiber cables rated for 40G short-reach applications and follow the equipment vendor’s compatibility list to ensure full interoperability. Handle the transceiver by its housing, avoid touching optical ferrules, and keep protective caps on when not in use. Confirm that the host device supports 40G QSFP modules and any digital diagnostic features you intend to use.
