The QSFP-40G-PLR4 is a high-performance 40GbE QSFP+ optical transceiver designed for long-reach data center and enterprise network deployments. Operating over single-mode fiber (SMF) at a 1310nm wavelength, it supports distances up to 10km and enables high-density connectivity. A key feature of this module is its ability to operate in breakout mode, allowing a single 40G port to be split into four independent 10G-LR connections for flexible network scaling.
Core Specifications
- Form Factor: QSFP+
- Data Rate: 40Gbps (4 x 10.3125Gbps lanes)
- Wavelength: 1310nm
- Max Distance: Up to 10km
- Fiber Type: Single-Mode Fiber (SMF)
- Connector: MTP/MPO-12 (APC required)
- Hot-Pluggable: Yes
Performance & Features
- Supports 40GBASE-PLR4 standard
- Breakout Capability: 4x10G-LR over SMF
- Digital Optical Monitoring (DOM/DDM) support
- Low power consumption: <2.5W typical
- High port density for data center environments
Compatibility & Standards
- Compliant with QSFP+ MSA and SFF-8436 standards
- Designed for Arista Networks switches (QSFP-40G-PLR4)
- Compatible equivalents available for Cisco (QSFP-4X10G-LR-S) and other platforms
- Multi-vendor compatibility with systems supporting QSFP+ ports
Applications
- 40GbE data center interconnects
- Long-distance SMF links up to 10km
- 4x10G breakout to SFP+ LR ports
- Enterprise core, aggregation, and spine-leaf architectures
Fiber & Cabling Requirements
- Requires Single-Mode Fiber (SMF) only
- Uses MPO/MTP-12 APC connector
- For breakout: MPO-to-4xLC SMF cable required
- Utilizes 8 fibers (4 Tx / 4 Rx) within MPO-12
Important Notes
- Not compatible with multimode fiber (OM3/OM4)
- APC MPO cables are required to avoid signal reflection issues
- Breakout functionality requires compatible switch configuration and cables
- Ensure proper polarity and fiber type when deploying
This QSFP-40G-PLR4 transceiver is a reliable and scalable solution for high-speed networking, offering long-range connectivity and flexible 4x10G breakout capability for modern data center environments.
