Question 1

What devices support the Arista Networks 40GBASE-PLR4L QSFP+ module?

Accepted Answer

The module works with networking switches and routers that support QSFP+ optical transceivers. It is commonly deployed in Arista switches and other enterprise networking equipment supporting 40GbE optical connectivity.

Question 2

Is the Arista 40GBASE-PLR4L QSFP+ compatible with single-mode fiber?

Accepted Answer

Yes. This module operates over single-mode fiber infrastructure using an MPO-12 optical connector. It is commonly used in enterprise fiber backbones and structured data center cabling environments.

Question 3

What is the maximum transmission distance of this module?

Accepted Answer

The optical design supports reliable signal transmission up to 2 kilometers over single-mode fiber. This makes it suitable for campus networks, building interconnects, and medium-distance data center links.

Question 4

Does the Arista 40GBASE-PLR4L QSFP+ module generate significant heat?

Accepted Answer

No. The module operates with controlled power consumption, allowing stable thermal behavior even inside high-density switch environments where multiple QSFP+ modules are installed.

Question 5

Can this module be used in data center spine-leaf networks?

Accepted Answer

Yes. Many network architects deploy this module for spine-leaf topologies, especially when connecting leaf switches to aggregation or spine switches across medium-distance fiber links.

Question 6

Arista 40GBASE-PLR4L vs LR4 QSFP+ module — what is the difference?

Accepted Answer

PLR4 modules typically use parallel CWDM optical channels and MPO connectors, while LR4 modules operate using duplex LC fiber connections. PLR4 modules are common in structured fiber infrastructure within large data centers.

Question 7

What is the power consumption of the Arista 40GBASE-PLR4L QSFP+ module?

Accepted Answer

The module is designed with efficient optical components and operates with relatively low power usage for high-speed QSFP+ optics. This makes it suitable for switches with many active transceivers.

Question 8

What is the price of Arista Networks 40GBASE-PLR4L QSFP+ module in Bangladesh?

Accepted Answer

Pricing may vary depending on supply and enterprise deployment quantities. For the latest Arista Networks 40GBASE-PLR4L QSFP+ price in Bangladesh, check availability directly at PCB Store Dhaka.

Question 9

Is the Arista 40GBASE-PLR4L QSFP+ module available at PCB Store?

Accepted Answer

Yes. The module is available through PCB Store, a trusted supplier of networking hardware in Bangladesh. Businesses can purchase it with warranty support and technical assistance.
