BlueOptics QSFP-40G-SR4 network transceiver module 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4 network transceiver module is a hot-pluggable optical module engineered for short-range 40 Gigabit Ethernet links. It supports a maximum data transfer rate of 40000 Mbit/s and transmits using an 850 nm VCSEL-based optical interface. Designed for rack environments, the QSFP form factor consolidates four lanes into a single pluggable unit to enable high-density aggregation and straightforward integration into compatible switches, routers and network interface cards.

Advantages

The module provides compact, high-bandwidth connectivity in a QSFP form factor that reduces port density and cable complexity compared with multiple SFP modules. Operation at 850 nm enables established multimode fiber compatibility for short-reach links. The transceiver supports standardized electrical and optical interfaces for interoperability with equipment that accepts QSFP short-range modules, delivering predictable performance and stable throughput at the specified 40 Gbit/s class.

Key specifications

How to use

Install the transceiver into a compatible QSFP port on a switch, router or network interface card while the host device is powered on if the equipment supports hot-plugging. Ensure you use appropriate multimode fiber patch cords and correct polarity when connecting. Verify link status and negotiated speed via the host device management interface or CLI after insertion. Follow any vendor-specific provisioning steps required by the network equipment, such as enabling the port or configuring VLANs and link aggregation if needed.

Recommendations

Use high-quality OM3 or OM4 multimode fiber for optimal short-reach performance and maintain clean fiber connectors to minimise insertion loss. Confirm compatibility with the host equipment's supported QSFP short-range modules and keep firmware or driver software up to date for reliable operation.
