## Summary description

The BlueOptics FN-TRAN-QSFP+SR 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 QSFP type module is ideal for data centers and high-performance networking applications, providing reliable connectivity with a lightweight design of only 20 g.

## Long description

The BlueOptics FN-TRAN-QSFP+SR network transceiver module is a compact QSFP optical module designed for short-range, high-speed data links. Supporting an aggregate data rate of up to 40000 Mbit/s and using an 850 nm wavelength, this module is intended for use in data centre and enterprise networking environments where high throughput and low-latency optical connections are required. The module's silver housing and 20 g lightweight construction simplify handling and installation in compatible QSFP ports.
Advantages
This transceiver provides 40 Gbps connectivity in a single QSFP form factor, enabling dense port deployments and reduced cabling complexity. The use of an 850 nm wavelength makes it suitable for multimode fiber links over short distances, and the standardized QSFP interface ensures broad compatibility with switches, routers and network interface cards that accept QSFP modules. Its compact size and low weight ease hot-swap installation and minimize mechanical stress on chassis ports.
Suitable for
 Short-range multimode fiber links in data centers
 Aggregation and spine-leaf connections in high-performance networks
 High-bandwidth server uplinks and switch-to-switch links
Key specifications

How to use
Install the BlueOptics FN-TRAN-QSFP+SR by inserting it into a compatible QSFP port on a switch, router or network interface card until it seats securely. Connect appropriate multimode fiber patch cords to the module's optical interface following the transceiver and equipment guidelines for polarity and connector type. Ensure device firmware and port settings match the module's 40 Gbit/s operation and enable the port in the network device configuration. Handle the transceiver by its housing and use dust caps when the module is not connected.
Usage recommendations
Use this QSFP+SR transceiver with multimode fiber (MMF) cabling that meets industry standards for short-range 850 nm operation. Verify compatibility with your network equipment vendor's supported transceiver list and keep firmware and drivers updated. Store and transport the module in anti-static packaging and avoid touching optical interfaces to maintain signal quality.
