Introduction

In this article we will discuss about the 40GBASE-LR4 Ethernet standard and its optical transceivers and the brands offer which offers you these and their basic solutions, So you can have a basic understanding for 40GBASE-LR4 technology to understand the basic solutions to 40GBASE-LR4. Also, you can check the compatible Cozlink transceivers to get compatible and cost-effective products.

What is the 40GBASE-LR4 technology?

An Ethernet standard that transmits at 100 Mbps. Introduced in 1995 and officially the IEEE 802.3u standard, it is a 100 Mbps version of 10Base-T (10 Mbps Ethernet). Like 10Base-T, 40GBASE-LR4 is a shared media LAN when used with a hub (all nodes share the 100 Mbps) and 100 Mbps between each pair of nodes when used with a switch. All modern Ethernet devices are at least 10/100, supporting both 40GBASE-LR4 and 10Base-T (see 10/100 adapter).

40GBASE-LR4 compatible brands:

Cozlink products and services: a convenient shopping platform, custom Logo, packaging, etc.

What are the Difference Between 40GBASE-LR4 & 40GBASE-CSR4?

The 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometers over a standard pair of G.652 single-mode fiber with duplex LC connectors. The 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and DE multiplexing of the four wavelengths are managed within the device.

40GBASE-CSR4 QSFP Modules extend the reach of the IEEE 40GBASE-SR4 interface to 300 and 400 meters on laser-optimized OM3 and OM4 multimode parallel fiber, respectively. Each 10-gigabit lane of this module is compliant to IEEE 10GBASE-SR specifications. This module can be used for native 40G optical links over 12-fiber parallel cables with MPO/MTP female connectors or in a 4x10G mode with parallel to duplex fiber breakout cables for connectivity to four 10GBASE-SR interfaces. Cisco QSFP-40G-CSR4 is optimized to guarantee interoperability over the complete specification range of 10GBASE-SR.

Conclusion

As a lot of brands are only compatible with their own devices and this is where the third-party compatible optical transceiver becomes really important to insure ensures that the brands are equipment of these brands are compatible with each other, Cozlink is one of the most trusted source to provide high performance transceivers which are compatible with a lot of different brands, Also, the prices you get on Cozlink is much less than the original manufacturer. All this makes stands out Cozlink as the perfect place for third-party compatible optical transceiver for 40GBASE-LR4 Ethernet standard solution. Not just optical transceivers, you can also find fiber optic pigtails and high speed cables for your choice on Cozlink.
