## Summary description

The BlueOptics 40G-QSFP-SR4 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. Ideal for data centers and high-performance networks, it ensures reliable connectivity and efficient data transmission.

## Long description

The BlueOptics 40G-QSFP-SR4 is a fiber optic transceiver module designed for short-reach, high-speed links in data center and enterprise networking environments. Supporting a 40 Gbit/s aggregate data rate and operating at an 850 nm wavelength, this QSFP SR4 module provides four parallel lanes for multi-mode fiber connections and is intended for use in switches, routers and servers that accept QSFP form-factor optics.
Advantages
This transceiver delivers 40 Gbit/s performance with a compact QSFP package suited for dense installations. Using 850 nm optics and SR4 parallel transmission, it supports reliable short-distance links over multi-mode fiber while maintaining low power consumption and predictable thermal characteristics. The module’s standard QSFP interface ensures compatibility with equipment that supports QSFP optics and simplifies upgrades to higher port densities.
Suitable for
40 Gbit/s uplinks between switches in data centers
High-performance server interconnects within racks
Short-range fiber aggregation and distribution links over multi-mode fiber
Network equipment requiring QSFP SR4 form-factor optics
Key specifications
Form factor: QSFP (Quad Small Form-factor Pluggable)
Data rate: up to 40 Gbit/s aggregate
Wavelength: 850 nm
Transmission type: SR4 parallel multimode fiber
Typical reach: short-reach links over multimode fiber (dependent on fiber type and channel conditions)
Compatibility: designed for QSFP ports in networking equipment
How to use
Install the transceiver into a compatible QSFP port following the equipment manufacturer’s hot-plug guidelines. Connect appropriate multi-mode fiber cables with the correct MPO/MTP connectors for SR4 parallel lanes, ensuring proper fiber polarity and connector cleanliness. Verify link status and speed on the host device management interface and monitor for any alarms or signal degradation. For safety, handle the optical interfaces with dust caps when not in use and avoid touching the fiber endfaces.
Usage recommendations
Use high-quality OM3 or OM4 multimode fiber and factory-terminated MPO/MTP trunk cables to achieve expected short-reach performance. Ensure firmware and compatibility lists on switches or servers are checked before deployment to confirm interoperability with QSFP SR4 optics.
