Product Description

Arista Networks 40GBASE-PLR4L QSFP+ 1310nm 2km Module

Struggling with unstable 40G links or signal loss across long fiber runs? The Arista Networks 40GBASE-PLR4L QSFP+ 1310nm 2km Module addresses that exact network bottleneck in modern data environments.

High-speed switching infrastructure depends on stable optical connectivity. In enterprise networks, campus backbones, and high-density data racks, unreliable fiber links create packet loss, jitter, and operational downtime. This QSFP+ optical module provides reliable 40G connectivity designed for demanding fiber deployments.

Network engineers, system integrators, and data center operators in Bangladesh frequently deploy this module in aggregation layers, leaf-spine fabrics, and enterprise backbones. At PCB Store, it’s a trusted choice in the Network And Router category, particularly within Sfp Module And Fiber solutions.

Arista Networks 40GBASE-PLR4L QSFP+ Module Overview for 40G Fiber Networks

Modern infrastructure requires scalable bandwidth between switches, storage systems, and compute nodes. The Arista Networks 40GBASE-PLR4L QSFP+ 1310nm 2km Module provides stable long-reach optical connectivity using single-mode fiber.

Its architecture supports four parallel optical channels over a CWDM transmission scheme. That configuration helps maintain consistent signal integrity across medium-distance fiber deployments often found in enterprise campuses and distributed server environments.

Data center operators benefit from:

• Stable 40GbE optical communication across racks and network segments
• Reliable long-distance connectivity between switches
• Low power optical transceiver design suitable for dense networking hardware
• Compatibility with Arista infrastructure and similar enterprise networking equipment

The result is predictable network performance even under high traffic conditions.

Optical Transmission Technology Behind the Arista 40GBASE-PLR4L QSFP+

Network stability depends heavily on optical signaling quality. This module uses distributed feedback CWDM transmitters paired with PIN receiver technology to maintain strong optical signals across fiber links.

The optical architecture supports parallel transmission channels over single-mode fiber, which improves reliability for long-distance connections inside enterprise networks.

Key technical highlights include:

• CWDM optical transmission operating at 1310nm wavelength
• Multi-channel optical lanes supporting high aggregate throughput
• MPO-12 connector designed for structured fiber deployments
• Strong signal tolerance with balanced transmit and receive parameters

These optical characteristics allow network architects to deploy reliable high-speed links between data center zones, aggregation switches, and distribution layers.

Efficient Power Design for High-Density Network Hardware

Data centers prioritize thermal efficiency and power stability. Optical modules installed in high-density switches must maintain reliable performance without adding unnecessary thermal load.

This module operates with controlled power consumption levels that suit modern switching platforms. It helps maintain stable thermal conditions even in rack environments where dozens of optical modules operate simultaneously.

Benefits for infrastructure teams include:

• Reduced power draw in high-port networking switches
• Stable optical output across operational temperature ranges
• Reliable performance during sustained network workloads

For operators managing dense switch deployments in Bangladesh data centers, these characteristics matter for long-term reliability.

Real Deployment Scenarios for the Arista 40GBASE-PLR4L QSFP+ Module

High-capacity optical links are common across many professional network environments. The Arista Networks 40GBASE-PLR4L QSFP+ 1310nm 2km Module fits multiple practical deployment scenarios.

Enterprise Data Center Interconnects

Large organizations often run multiple server racks across different rooms or floors. This module supports stable optical communication between top-of-rack switches and aggregation switches.

ISP and Network Backbone Infrastructure

Internet service providers frequently deploy single-mode fiber links across building infrastructure. The module supports long-distance transmission across those backbone segments.

University and Campus Networks

Educational campuses connect multiple buildings through fiber backbone networks. The module provides reliable connectivity between core switches across these distributed environments.

Virtualization and Storage Networks

Virtual machine clusters and storage arrays generate heavy east-west traffic. High-capacity optical connectivity prevents network congestion in these workloads.

Across Bangladesh, integrators often source these optical modules from PCB Store Dhaka for enterprise and infrastructure projects.

Compatibility and Integration within Arista Networking Ecosystems

Optical transceiver compatibility determines whether a network module operates reliably with switch hardware. This QSFP+ module is designed for Arista networking platforms and compatible enterprise switch systems supporting 40G QSFP+ optics.

Its protocol support aligns with industry optical standards used in high-speed networking equipment. That compatibility allows straightforward integration into existing fiber infrastructures.

System administrators benefit from:

• Easy installation in QSFP+ switch ports
• Stable interoperability with supported networking platforms
• Reliable optical communication in enterprise fiber topologies

Proper compatibility reduces deployment complexity during network expansion.
