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.
