40G QSFP transceiver BlueOptics 40G-QSFP-LSR-MM850-BO 40000 Mbit/s

The BlueOptics 40G-QSFP-LSR-MM850-BO is a QSFP transceiver module for 40 Gigabit Ethernet links, engineered for short-reach multimode fiber connections. Designed to support data rates up to 40,000 Mbit/s and a maximum transmission distance of 300 m over OM3/OM4 multimode fiber with MTP/MPO termination, this silver-coloured module offers a compact form factor and a lightweight design of approximately 40 g. With an MTBF rating of 1,000,000 hours, it is intended for use in data center switches, servers and high-density network equipment that require reliable short-range 40G connectivity.

Advantages

The transceiver provides a standardized QSFP form factor for straightforward insertion into compatible 40 Gigabit Ethernet ports and supports high aggregate throughput for server-to-switch and switch-to-switch links. Its MTP/MPO fiber connector enables multi-fiber parallel transmission which simplifies cabling for short-range multimode deployments. The module’s low weight and compact dimensions reduce port density constraints, and the high MTBF value indicates long-term operational reliability under normal network conditions.

Suitable for

• Data center uplinks and leaf-spine topologies
• Short-reach server interconnects over multimode fiber
• High-density switch ports requiring QSFP optics
• Environments using MTP/MPO trunk cabling

How to use

Install the module by inserting the QSFP connector into a compatible 40 Gigabit Ethernet port on a switch or network device while following the host device’s hot-plug and handling guidelines. Connect the MTP/MPO multi-fiber cable to the transceiver ensuring correct polarity and connector orientation. Verify link status through the network device’s management interface and confirm that transceiver parameters such as speed and duplex are negotiated correctly. Handle the module with electrostatic discharge precautions and keep protective caps on the connector when not in use to avoid contamination or damage.

Recommendations

For reliable performance, use the transceiver with compatible switches and certified OM3/OM4 multimode fiber cabling and MTP/MPO connectors. Maintain clean connector endfaces with proper inspection and cleaning tools, respect the specified maximum distance of 300 m for 40G links, and follow vendor compatibility guidelines to ensure interoperability and stable link operation.
