40G QSFP+ Transceiver Module
The 40G QSFP+ Transceiver Module is designed for high-performance data center, enterprise backbone, and cloud networking applications, delivering reliable 40Gbps aggregated bandwidth for high-density environments.
Built according to IEEE 802.3ba and QSFP+ MSA standards, this module ensures full interoperability with major networking platforms while maintaining stable performance and low latency.
It supports multiple transmission types including SR4 (short range multimode fiber), LR4/ER4 (long range single-mode fiber), DAC (direct attach copper cable), and AOC (active optical cable), providing flexible deployment options for different network architectures.
With hot-pluggable QSFP+ form factor and low power consumption design, it is ideal for scalable network upgrades from 10G/25G to 40G infrastructure.
Key Features
- Supports 40Gbps high-speed transmission
- QSFP+ hot-pluggable form factor
- SR4 / LR4 / ER4 / DAC / AOC options available
- MPO-12 (SR4) and LC (LR4/ER4) interfaces
- Transmission distance up to 100m–150m (MMF)
- Transmission distance up to 10km–40km (SMF)
- Low power consumption (<3.5W typical)
- Digital Diagnostic Monitoring (DDM/DOM) support
- Fully compliant with IEEE 802.3ba and QSFP+ MSA standards
- Compatible with major networking vendors
Technical Overview
The QSFP+ 40G transceiver integrates four independent 10Gbps channels into a single module, enabling high-density 40G Ethernet connectivity.
SR4 versions use VCSEL laser technology operating at 850nm over multimode fiber, while LR4 and ER4 versions utilize 1310nm or 1550nm wavelengths over single-mode fiber for long-distance transmission.
DAC and AOC variants provide cost-effective, low-latency direct interconnect solutions for short-range rack-to-rack connections.
