## Summary description

The BlueOptics QSFP-40G-SR4-CO is a fiber optic transceiver module designed for high-speed data transfer. It supports a maximum data rate of 40000 Mbit/s and operates at a wavelength of 850 nm. This module is ideal for data center applications and high-performance networking, providing reliable connectivity and efficient data transmission.

## Long description

The BlueOptics QSFP-40G-SR4-CO is a high-density fiber optic transceiver module designed for 40 Gbit/s short-reach links in data centre and enterprise networks. Compatible with QSFP interfaces, this module uses an 850 nm wavelength and supports a maximum data transfer rate of 40000 Mbit/s. It provides multi-channel optical connectivity for switch-to-switch, server-to-switch or aggregation links where reliable, low-latency transmission and compact form factor are required.
Advantages
The transceiver delivers standard-compliant 40G optical performance in a compact QSFP form factor, enabling high port density in network equipment. Operating at 850 nm, it is suitable for multimode fiber runs and supports high aggregate throughput without active components beyond the module itself. The product is designed for interoperability with QSFP ports and offers stable data transfer at the specified maximum rate.
Suitable for
 40G short-reach links in data centres and server rooms
 Top-of-rack and spine leaf switch connections
 High-performance networking and aggregation links
 Replacement or upgrade of QSFP-based optical ports
Key specifications
 Interface type: QSFP
 Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
 Operating wavelength: 850 nm
 Form factor: QSFP (quad small form-factor pluggable)
 Application range: short-reach multimode fibre links
How to use
Install the module into a compatible QSFP port on network equipment while the device is powered down or following the manufacturer’s hot‑swap guidelines. Connect appropriate multimode fiber cabling terminated with the correct MPO/MTP or breakout connector as required by the port and system design. Verify link status through the switch or transceiver monitoring tools, and ensure optical budgets and fibre type meet the short-reach specifications for 850 nm operation.
Usage recommendations
Use multimode OM3/OM4 fibre for optimal reach and performance at 850 nm, maintain clean connector end faces, and follow ESD handling procedures when fitting or removing the QSFP module to preserve reliability and signal integrity.
